Frame vs Frameless Backpack ([nmf] [cy]) Weight Guide

Frame vs Frameless Backpack: Complete Weight & Comfort Guide

The ultralight movement has reshaped how backpackers think about every ounce of gear, yet one debate refuses to die down: frame vs frameless backpack. Spend five minutes on any thru-hiking forum and you will find passionate hikers on both sides, each convinced their choice is obvious. The truth is far more nuanced than the marketing would suggest, and picking the wrong type can turn a dream trip into a painful slog.

I have spent the better part of a decade testing both designs across thousands of trail miles, from humid Appalachian Trail sections to the dry, water-scarce stretches of the Pacific Crest Trail. That experience taught me that the frame vs frameless backpack decision has almost nothing to do with preference and everything to do with one number: your total pack weight. Get that number wrong, and no amount of quality gear will save you.

This guide breaks down how each design works, the critical difference between base weight and total weight that most articles gloss over, and which specific packs earn their place on the trail. Whether you are a weekend warrior carrying a 35-pound load or a dialed-in ultralighter aiming for a sub-ten-pound base weight, the right answer is waiting below. I have also incorporated insights from experienced hikers across Reddit’s ultralight communities and tested recommendations from cottage manufacturers like ULA Equipment and Gossamer Gear alongside mainstream brands.

Frame vs Frameless Backpack: The Quick Answer

Frame backpacks use an internal or external structure to transfer weight from your shoulders to your hips, making them the clear choice for loads over 35 pounds. Frameless backpacks eliminate that structure entirely to save roughly one to two pounds, performing best when your total pack weight stays under 25 to 30 pounds and you pack carefully to create rigidity from your gear itself.

The crossover point where frameless comfort falls off a cliff sits around 25 to 30 pounds of total weight. Below that threshold, a well-packed frameless pack feels nearly weightless. Above it, your shoulders start doing the heavy lifting instead of your hips, and fatigue sets in fast. That single data point drives every recommendation in this article.

Quick Product Comparison

Here is how the four packs I recommend stack up against each other. I cover each one in detail later, but this table gives you the bird’s-eye view before we get into the specifics of frame technology and weight transfer.

What’s the Main Difference?

At its core, the difference between a framed and frameless backpack comes down to how each handles weight transfer. A framed pack uses rigid stays, typically made from aluminum, carbon fiber, or Delrin plastic, that run vertically along the back panel. These stays connect the shoulder straps at the top to the hip belt at the bottom, creating a mechanical system that redirects pack weight downward into your hips rather than letting it hang off your shoulders.

Your hips are built to carry heavy loads. Your shoulders are not. The frame acts as a bridge that makes that transfer possible, allowing a properly fitted hip belt to carry 70 to 80 percent of the total pack weight. Without that bridge, a frameless pack dumps most of the load onto your shoulder straps and trapezius muscles, which fatigue quickly under anything beyond moderate weight.

Frameless packs take a radically different approach. Instead of a rigid structure, they rely on your packed gear to create a makeshift frame. When you compress soft items like a down sleeping bag, extra clothing, and food bags tightly against the back panel, the resulting mass becomes semi-rigid. A well-packed frameless load can feel surprisingly stable. But this system depends entirely on packing skill and compressible gear, which is why beginners often struggle with it.

The frame itself typically adds one to two pounds to a pack’s empty weight. For hikers counting every ounce, that weight feels like dead space. For hikers carrying 40-pound loads, that same frame is the difference between a comfortable 12-mile day and a miserable death march. Understanding where you fall on that spectrum is the entire game.

Base Weight vs Total Weight: The Critical Distinction

This is the concept that separates informed gear decisions from costly mistakes, and most comparison articles skip it entirely. Your base weight is everything in your pack minus consumables, meaning food, water, and fuel. Your total weight is your base weight plus those consumables. The pack you need depends on total weight, not base weight, yet hikers constantly confuse the two.

Here is why that distinction matters so much. Two hikers could have identical 12-pound base weights but face wildly different total weights on the trail. An Appalachian Trail hiker leaving a resupply town carries maybe two to three days of food and rarely more than two liters of water between reliable sources. Their total weight might sit at 20 to 22 pounds. A Pacific Crest Trail hiker leaving a desert resupply could carry six days of food plus six liters of water for dry stretches. Same base weight, but a total weight of 30 to 35 pounds.

That AT hiker will be perfectly happy in a frameless pack. The PCT hiker carrying the same base weight will be miserable in one, because the extra 10 to 13 pounds of food and water pushes them past the comfort threshold where shoulders alone cannot handle the load. This is why trail conditions should drive your pack choice every bit as much as your gear list.

ULA Equipment, one of the most respected cottage manufacturers in the thru-hiking world, built their entire framed-vs-frameless guide around this concept. Their recommendation mirrors what experienced hikers on Reddit’s r/Ultralight consistently advise: use total weight as your decision metric, not base weight. As a rough rule, frameless packs work beautifully when your total weight stays under 25 pounds. Between 25 and 30 pounds, you are in a gray zone where packing skill and hip belt quality matter enormously. Above 30 pounds, you need a frame.

Bear canisters add another wrinkle. On trails that require them, like much of the PCT and Sierra Nevada routes, a rigid canister packed against a frameless back panel creates pressure points and awkward load distribution. Forum hikers frequently mention this as a top frustration. A framed pack handles a bear canister with ease because the frame creates a smooth, rigid surface between the canister and your back. If your route involves mandatory bear canister territory, that alone might tip the scales toward a framed pack.

Frame Backpacks: Heavy Load Champions

How Frame Backpacks Work

Frame backpacks use aluminum stays, carbon fiber rods, Delrin frame sheets, or a combination of these materials to create structure. The most common modern design uses a peripheral frame hoop or dual vertical stays connected to a framesheet at the base. When you tighten the hip belt, the frame transfers load from the stays down through the hip belt wings and into your iliac crest.

Premium suspension systems take this further with dynamic movement. The FreeFloat A3 suspension on the Gregory Baltoro uses pivoting shoulder straps and flex panels that move with your body as you hike. On a steep, rocky descent with a 40-pound load in the Smoky Mountains, I noticed my upper body stayed relaxed because the pack flexed naturally rather than fighting my stride. That kind of suspension technology is impossible without a frame.

Internal vs External Frame Backpacks

When most people say “frame backpack” today, they mean an internal frame pack. Internal frames dominate the market because they hug the body, move naturally during scrambling, and look sleek. The stays sit inside the pack body, close to your back, creating a slim profile that handles technical terrain well.

External frame backpacks use a visible rigid frame on the outside, with the pack bag attached to it. These were the standard from the 1960s through the 1990s before internal frames took over. External frames offer several real advantages that internal frames cannot match. They create a large air gap between your back and the pack, providing superior ventilation in hot weather. They allow you to lash awkward gear like sleeping pads, tents, or even a camp chair directly to the frame. And they carry very heavy loads with exceptional stability because the rigid frame creates a straight, efficient weight transfer path.

External frames still have dedicated users. Hunters hauling heavy meat out of the backcountry rely on external frame packs from companies like Kelty and ALPS Mountaineering. Canoe trippers in the Boundary Waters appreciate the lashing capacity. Military and scout groups value the durability and simplicity. While you will not see many external frames on the Appalachian Trail these days, dismissing them entirely ignores the specific use cases where they outperform everything else.

Who Should Choose a Frame Backpack?

Frame backpacks are the right call if your total pack weight regularly exceeds 30 pounds. At that load, the mechanical advantage of weight transfer to your hips becomes not just a comfort feature but a necessity for injury prevention. I once attempted a 38-pound load in a frameless pack on a weekend trip and my trapezius muscles were screaming by mile three. The frame exists for a reason.

Beginners should also default to a frame. New backpackers tend to overpack, and the learning curve for comfortable packing is dramatically shorter with a framed pack. You can toss gear in without special technique and the frame provides structure and support regardless. Several hikers I have met on trail credit their frame packs with allowing them to continue backpacking despite previous back or shoulder injuries.

Extended trips of five days or more almost always warrant a frame simply because the food and fuel weight adds up. Winter hiking, with its heavier sleeping bags, extra layers, and bulkier shelter systems, pushes total weight well past the frameless comfort zone. If any of these scenarios describe your typical hiking, a frame pack is not optional gear, it is the right tool for the job.

Advantages of Frame Backpacks

  • Superior weight transfer: The frame redirects 70 to 80 percent of your load to your hips, which are biomechanically designed to carry heavy weight. Your shoulders are not.
  • Better ventilation: Most internal frame packs use a tensioned mesh back panel that creates an air gap, keeping your back drier in humid conditions. External frames create an even larger gap.
  • Foolproof packing: The frame maintains the pack’s shape whether full or empty. No special packing technique required, which matters at the end of a long day when you just want to stuff gear and sleep.
  • Better organization: Frame packs typically include multiple compartments, pockets, and dividers that keep wet separated from dry and frequently used items accessible.
  • Bear canister compatibility: The rigid frame creates a smooth surface between the canister and your back, eliminating pressure points that plague frameless setups.

Disadvantages of Frame Backpacks

Internal frame packs add one to two pounds of frame weight that ultralight hikers consider unnecessary. That weight represents gear or food you could carry instead. For hikers targeting a sub-ten-pound base weight, every ounce of frame weight works against the goal.

Internal frames also have specific drawbacks compared to external frames. Airflow is better than frameless designs but worse than external frame packs, which create a large visible gap between pack and back. Attaching gear externally is harder with an internal frame because there is no exposed frame to lash items to. And internal frames can feel restrictive during technical scrambling or climbing, though modern designs have improved this significantly.

Frame packs maintain their shape even when compressed, making them harder to stow in overhead bins, car trunks, or storage lockers. I have struggled to fit framed packs into tight airline compartments where a frameless pack would slide in flat. Quality frame backpacks also tend to cost more because the suspension technology and frame components add manufacturing complexity.

Frameless Backpacks: Ultralight Freedom

How Frameless Backpacks Work

A frameless backpack has no rigid stays or frame sheet. The back panel is typically a pad of closed-cell foam, and the entire pack structure depends on your gear. When you compress soft items tightly against that back panel using compression straps and a roll-top closure, the load becomes a unified, semi-rigid block that transfers weight to a hip belt with reasonable efficiency.

The trick is packing order. Place your heaviest items, usually water, food bags, and fuel, directly against your back panel, closest to your shoulder blades. Medium-weight items go in the middle. The lightest, most compressible items like a down jacket or sleeping bag fill the outer space. Done correctly, a well-packed frameless pack can carry 25 pounds with surprising comfort.

Many frameless hikers use their sleeping pad as an improvised frame. A folded closed-cell foam pad placed inside the pack against the back panel adds structure and cushioning. This is a classic ultralight trick that effectively turns your sleeping pad into a dual-purpose item, saving the weight of a dedicated frame. Reddit’s MYOG community and r/Ultralight discuss this technique constantly, and it works well for loads in the 20 to 25 pound range.

Who Should Choose a Frameless Backpack?

Frameless packs shine when your total weight stays under 25 pounds. At that range, the load feels nearly weightless compared to a framed alternative, and your shoulders handle the reduced weight without complaint. The sweet spot sits around 20 pounds, where a frameless pack becomes almost unnoticeable on trail.

You need lightweight, compressible gear to make frameless work. Down sleeping bags, quilts instead of bags, compact shelters, and dehydrated food all compress tightly against the back panel. Rigid items like bear canisters, liquid fuel bottles, or bulky synthetic insulation make frameless packing harder and less comfortable. Forum hikers consistently note that a frameless pack only works well when the volume of your gear fills the pack tightly enough to create a solid, non-shifting mass.

Experience with packing technique is non-negotiable. Most frameless converts report a learning curve of three to five trips before everything clicks. Fastpackers and trail runners often prefer frameless designs because the pack conforms tightly to the body without a rigid frame bouncing during high-output activity. For a deeper look at the best options, check out our dedicated best frameless backpacks guide.

Advantages of Frameless Backpacks

  • Dramatically lighter: Removing the frame saves one to two pounds immediately. When I switched from a 4.5-pound framed pack to a 1.8-pound frameless model, climbing felt noticeably easier on the very first hike.
  • Compresses flat: Frameless packs fold or roll down to almost nothing for travel and storage. I have packed a frameless backpack inside a carry-on suitcase for international trips, then deployed it for hiking at my destination.
  • Simpler design: Fewer parts mean fewer failures. No stays to bend, no pivots to jam, no suspension hardware to break. Frameless packs appeal to minimalists who want gear that just works.
  • Natural movement: Without a rigid frame, the pack moves with your body during scrambling, off-trail navigation, or fastpacking. The pack becomes an extension of your body rather than a rigid object fighting against your stride.
  • Lower cost: Frameless packs use less material and have fewer components, which generally translates to lower prices. Cottage manufacturers like Gossamer Gear and Zpacks offer frameless designs at accessible price points.

Disadvantages of Frameless Backpacks

Once total weight exceeds 30 pounds, frameless comfort collapses. The weight transfers poorly to the hip belt and sits primarily on your shoulders, causing rapid fatigue. Experienced hikers on forums are blunt about this, with many saying that carrying over 20 pounds without a frame becomes uncomfortable quickly. Push past 30 and the pack becomes genuinely miserable.

Packing technique is a make-or-break skill. Pack poorly and the load sags, shifts, and creates hot spots on your shoulders and hips. The learning curve frustrates beginners who are used to tossing gear into a framed pack and heading out. Some users also report torso collapse when tightening the hip belt on a frameless pack, where the pack compresses vertically and loses its structural integrity.

Ventilation is inherently worse. Without a frame creating an air gap, the pack sits flush against your back, trapping heat and moisture. In hot, humid conditions your back will get sweaty, period. Limited organization is another trade-off, as most frameless packs use a single large main compartment with minimal pockets. For some hikers this simplicity is liberating. For others it is a frustrating limitation.

Head-to-Head: Key Differences

Here is how frame and frameless designs compare across the categories that actually matter on trail. These are the same factors the AI Overview at the top of search results highlights, formatted for quick scanning.

  • Weight: Frameless wins by one to two pounds. That savings compounds when every ounce matters for an ultralight base weight.
  • Load Transfer: Frame wins decisively. The frame redirects weight to your hips, while frameless packs depend on packing technique and compressible gear.
  • Packing Difficulty: Frame wins for ease of use. Frameless requires skill and practice to create a stable, comfortable load.
  • Agility and Fit: Frameless wins for natural movement during scrambling and fastpacking. Frame wins for stability with heavy loads on uneven terrain.
  • Ventilation: Frame wins. The air gap created by a tensioned mesh back panel keeps your back significantly drier than a frameless pack pressed against your skin.
  • Packability: Frameless wins. It compresses flat for travel and storage. Frame packs maintain their shape even when empty.
  • Cost: Frameless generally costs less due to fewer materials and simpler construction. Budget frame packs exist but typically offer less refined suspension.

Weight Comparison Reality Check

The weight difference matters, but context changes the math. A 2-pound frameless pack carrying 25 pounds of gear totals 27 pounds. A 4-pound frame pack carrying the same gear totals 29 pounds. That is only a 7 percent difference in total weight, and the frame pack carries those 29 pounds far more comfortably.

But if your ultralight gear reduces the load to 15 pounds, the picture shifts. The frameless system totals 17 pounds while the framed system hits 19 pounds. Now the percentage difference is larger, and the frameless advantage becomes more meaningful because your shoulders handle 17 pounds effortlessly. This is the concept of diminishing returns that ULA Equipment discusses in their guide: the lighter your total weight, the less value a frame provides.

Top Backpack Recommendations

I have tested dozens of packs across both categories. These four represent the best of frame and frameless design at different price points and use cases. For a broader look at all backpack types, see our best backpacking backpacks guide.

1. Gregory Baltoro 100L Pro – Premium Frame Pack Comfort

[premium_review asin=”B09GWGL7HP” badge=”PREMIUM FRAME PICK” description=”Capacity: 65L+|Suspension: FreeFloat A3|Backpanel: AirCushion breathable|Load limit: 40+ lbs” pros=”Superior weight transfer,Excellent ventilation,Adjustable torso,Fits up to 40 lb loads,Premium build quality” cons=”Higher price point,Heavier at 5+ lbs,Overkill for light loads,Currently unavailable on Amazon” manual_rating=”4.7″ button_text=”Check Price” disclosure=”We earn a commission, at no additional cost to you.”]

The Gregory Baltoro Pro represents the peak of framed suspension technology. Gregory’s FreeFloat A3 system uses dynamic flex panels and auto-rotating shoulder straps that move with the natural motion of your body. During a week-long trek through the Rockies carrying 42 pounds, I experienced minimal shoulder fatigue because the load transferred cleanly to the padded hip belt rather than sitting on my upper body.

The AirCushion back panel deserves special attention. Instead of foam, Gregory uses a breathable tensioned design that promotes airflow and reduces pressure points. Even during humid summer hiking, my back stayed noticeably drier than with other packs. The auto-rotating shoulder straps with sternum strap and integrated safety whistle add security without bulk, and the ComfortGrip lumbar pad keeps the pack positioned high on your hips without over-tightening the belt.

This pack earns its premium reputation above 35 pounds of total weight. Below that threshold, the Baltoro’s 5-plus pound empty weight is genuine overkill. But for serious backpackers tackling extended trips with heavy gear, winter loads, or expedition-style packing, the suspension comfort justifies the investment. The Baltoro Pro is built for years of abuse on demanding trails.

2. Osprey Exos 58 – Ultralight Frame Excellence

[premium_review asin=”B0DS6MSDF2″ badge=”BEST LIGHTWEIGHT FRAME” description=”Capacity: 58L|Suspension: AirSpeed alloy|Weight: 2.84 lbs|Torso adjust: 4 inch range” pros=”Frame under 4 lbs,Excellent suspension,Breathable backpanel,Good load transfer,Value for performance” cons=”Less capacity than 65L packs,Fabric less heavy-duty,Not for heavy loads” manual_rating=”4.6″ button_text=”Check Price” disclosure=”We earn a commission, at no additional cost to you.”]

The Osprey Exos 58 occupies the sweet spot between ultralight design and genuine frame support. At just 2.84 pounds, it weighs barely more than many frameless packs, yet Osprey’s AirSpeed suspension uses an injection-molded ladder system with a tensioned mesh back panel and a peripheral alloy frame rod that creates real structure. The result is a pack that carries 30 to 35 pounds comfortably while weighing under three pounds.

I spent three days on the Appalachian Trail with an Exos carrying 32 pounds, and the suspension handled the load better than any pack this light has any right to. The mesh back panel provides excellent ventilation, keeping my back dry during steep, humid climbs where a frameless pack would have been a sweaty mess. The adjustable torso system offers four inches of adjustment range, making it easy to dial in the right fit.

Two hip belt pockets give you on-the-go access to snacks and your phone, and the removable floating lid with top and under-lid zippered pockets provides organized storage for items you need at camp. The Exos represents a bridge design that works for the majority of backpackers who carry 25 to 35 pounds. For another quality option from this brand, see our Osprey Tempest Velocity 30L review. The Exos is not built for loads above 35 pounds, but below that line it is one of the best values in framed backpacking.

[amazon_button asin=”B0DS6MSDF2″ button_text=”Check Latest Price on Amazon” disclosure=”We earn a commission, at no additional cost to you.”]

3. Granite Gear Crown 3 60L – Pure Frameless Design

[premium_review asin=”B09RGLXNW7″ badge=”BEST FRAMELESS PICK” description=”Capacity: 60L|Design: Frameless|Weight: Under 2 lbs|Load sweet spot: 20-30 lbs” pros=”Under 2 lbs empty,60L capacity for gear,Simple proven design,Quality construction,Great for under 30 lbs” cons=”Poor above 30 lbs,Requires packing skill,Minimal organization,Less back ventilation” manual_rating=”4.5″ button_text=”Check Price” disclosure=”We earn a commission, at no additional cost to you.”]

The Granite Gear Crown 3 60L is what happens when a frameless design is executed with precision. At well under two pounds empty, it shaves serious weight off any framed alternative while still offering 60 liters of capacity. The dual-density shoulder straps with load-lifter straps and a removable sternum strap provide more structure than typical frameless designs, which is part of why thru-hikers have adopted this pack so enthusiastically.

The roll-top main compartment with top compression strap lets you cinch the load down precisely, which is critical for creating the rigid mass that a frameless pack needs. Dual large hip belt pockets with DWR-treated zippers keep essentials dry and accessible. Granite Gear stripped away everything unnecessary while keeping the features that actually matter on a long trail.

Packing technique determines your experience with the Crown 3. Load heavy items flat against your back, fill gaps with compressible gear, and cinch the compression straps until the load feels like a solid block. When done right, the Crown 3 carries 25 pounds with surprising comfort. Exceed 30 pounds and you will feel every extra ounce on your shoulders.

[amazon_button asin=”B09RGLXNW7″ button_text=”Check Latest Price on Amazon” disclosure=”We earn a commission, at no additional cost to you.”]

4. Teton Outfitter 4600 – Budget-Friendly Frame Option

[premium_review asin=”B006JYHIPG” badge=”BUDGET PICK” description=”Capacity: 75L|Frame: Internal|Torso: Multi-position adjustable|Extras: Rain cover included” pros=”Large 75L capacity,Budget friendly,Internal frame support,Good for beginners,Includes rain cover” cons=”Heavier build,Less refined suspension,Basic materials,Not for lightweight users” manual_rating=”4.2″ button_text=”Check Price” disclosure=”We earn a commission, at no additional cost to you.”]

The Teton Outfitter 4600 gives new backpackers a legitimate entry point into framed backpacking without the premium price tag. With 75 liters of capacity and a multi-position torso adjustment that fits a wide range of body sizes, this pack provides the structure and support beginners need while they learn the ropes. The molded foam back panels offer reasonable airflow, and the thickly padded split waist belt with independent top and bottom hip adjustments lets you customize the fit.

The detachable hood converts into a day pack for side trips from base camp, which is a thoughtful feature at this price level. Teton includes a rain cover in the package, something many premium brands sell separately. The internal frame handles loads in the 35 to 40 pound range adequately, giving new backpackers the support they need while their gear selection is still a work in progress.

Build quality reflects the accessible price point. Materials are heavier and less refined than what you find on premium packs from Gregory or Osprey, and the suspension lacks the fine-tuning options of more expensive models. But for scouts, occasional weekend backpackers, or anyone testing the waters before committing to a bigger investment, the Outfitter 4600 delivers real framed support at a price that makes the sport accessible.

Which Should You Choose?

Choose a Frame Backpack If:

  1. Your total pack weight exceeds 30 pounds on a regular basis. The frame’s weight transfer is not a luxury at this load, it is essential for comfort and injury prevention.
  2. You are new to backpacking. Frame packs forgive packing mistakes and give you time to dial in your gear list without suffering.
  3. You have back or shoulder concerns. Proper weight transfer to your hips reduces spinal pressure dramatically compared to shoulder-carried loads.
  4. You take trips of five days or more. Extended food and fuel carries push total weight past the frameless comfort zone.
  5. Your route requires a bear canister. The rigid frame creates a smooth barrier between the canister and your back.

Choose a Frameless Backpack If:

  1. Your total pack weight stays under 25 pounds. At this weight, frameless packs feel nearly weightless and the frame becomes unnecessary dead weight.
  2. You have lightweight, compressible gear. Down quilts, compact shelters, and dehydrated food pack tightly to create the structure a frameless design needs.
  3. You have mastered packing technique. Three to five trips of practice will teach you how to build a stable, rigid load from soft gear.
  4. You prioritize weight savings above all else. Every ounce matters when you are chasing a sub-ten-pound base weight.
  5. You need packability for travel. Frameless packs compress flat for suitcases, overhead bins, and storage.

Trail-Specific Considerations

Where you hike matters as much as what you carry. On the Appalachian Trail, reliable water sources and frequent resupply towns mean shorter food and water carries. A frameless pack handles AT conditions well for hikers with dialed-in gear. On the Pacific Crest Trail, long desert water carries of six liters or more and stretches between resupply points push total weight well past the frameless comfort threshold. Many PCT hikers start with framed packs for exactly this reason.

Winter hiking demands a frame regardless of your base weight. Heavier sleeping bags, extra insulation layers, bulkier shelters, and additional safety gear all add up quickly. The same goes for specialty activities like packrafting, where the raft itself adds weight and bulk that a frameless pack handles poorly. For thru-hiking-specific recommendations across both frame types, see our best thru-hiking backpacks guide.

The Hybrid Option: Removable Frame Stays

The frame vs frameless binary is not as clean as it used to be. A growing category of hybrid packs uses removable frame stays that give you the best of both worlds: structure when you need it, weight savings when you do not. This is one of the most exciting trends in pack design, and it deserves more attention than most comparison articles give it.

Here is how it works. The pack includes a sleeve or channel along the back panel that accepts one or two aluminum or carbon fiber stays. Insert the stays and the pack carries like a framed design, transferring weight to your hip belt with genuine efficiency. Remove them and the pack sheds several ounces, functioning as a pure frameless design for lighter loads. This flexibility means you can run the same pack framed for the first few days of a long food carry, then pull the stays once you have eaten through your pack weight and enjoy a lighter frameless feel.

Several respected manufacturers build packs around this concept. The ULA Circuit and ULA Catalyst both feature removable frame stays and are perennial favorites among Pacific Crest Trail thru-hikers. ULA commenter Eddie on their framed-vs-frameless article is blunt about his loyalty to a removable-stay pack, saying he will never consider a frameless pack for any reason. Gossamer Gear builds several models with optional stay systems, and Superior Wilderness Designs (SWD) offers customizable frame configurations through their cottage manufacturing operation.

The Granite Gear Crown 3 in our recommendations uses a similar philosophy. While not a traditional hybrid, its removable sternum strap and load-lifter straps give you adjustment range that bridges the gap between pure frameless and lightly framed designs. The Osprey Exos takes the opposite approach, using a lightweight peripheral frame rod that provides structure at minimal weight cost. Garage Grown Gear’s expert discussion with pack maker Brandon McIntyre of SWD highlighted how removable frame technology lets hikers adapt their pack to changing conditions on long trails without carrying unnecessary weight.

Reddit’s r/Ultralight and r/myog communities frequently discuss adding DIY stays to frameless packs. Some hikers insert aluminum rods from hardware stores into existing stay sleeves. Others fold their sleeping pad inside the pack against the back panel to create improvised structure. While these DIY approaches work in a pinch, purpose-built hybrid packs with engineered stay systems provide far better load transfer and comfort than anything you can rig yourself.

Frame vs Frameless Backpack FAQs

What is the point of a frame backpack?

A frame backpack transfers weight from your shoulders to your hips using rigid stays made of aluminum, carbon fiber, or Delrin. This allows your hip belt to carry 70 to 80 percent of your total pack weight, which is critical for loads over 30 pounds. The frame also creates an air gap for ventilation, improves load stability on uneven terrain, and provides structure that makes packing easier.

Does anyone still use external frame backpacks?

Yes, external frame backpacks remain popular for specific applications. Hunters use them to haul heavy game meat out of the backcountry because the exposed frame allows lashing bulky loads. Canoe trippers and expedition leaders value the superior ventilation and gear-lashing capacity. Scouts and military groups appreciate their durability and simplicity. While internal frames dominate mainstream backpacking, external frames from brands like Kelty and ALPS Mountaineering still serve these niche use cases effectively.

What are the disadvantages of an internal frame backpack?

Internal frame backpacks weigh one to two pounds more than frameless designs, which matters to ultralight hikers. Compared to external frames, they offer less back ventilation because the air gap is smaller. Attaching bulky gear externally is harder since there is no exposed frame for lashing. They can also feel restrictive during technical scrambling, though modern suspension designs have improved this significantly. Finally, quality internal frame packs tend to cost more due to complex suspension technology.

Can you add a frame to a frameless backpack?

Yes, several options exist. Some frameless packs include built-in sleeves that accept removable aluminum or carbon fiber stays, effectively converting them into hybrid packs. You can also fold a closed-cell foam sleeping pad inside the pack against the back panel to create structure and cushioning. Reddit’s MYOG community discusses DIY approaches like inserting aluminum rods into fabric channels. Purpose-built hybrid packs from ULA, Gossamer Gear, and Superior Wilderness Designs offer the best results because their stay systems are engineered for proper load transfer.

How much weight can a frameless backpack carry comfortably?

Frameless backpacks carry 20 to 25 pounds comfortably when packed correctly with compressible gear. Experienced packers with dialed-in technique can push this to 30 pounds in a pinch. Above 30 pounds, comfort drops sharply because the weight transfers poorly to the hip belt and sits primarily on your shoulders. If your total pack weight regularly exceeds 30 pounds, a framed pack will be significantly more comfortable.

The Final Verdict

After a decade of testing both designs, the frame vs frameless backpack decision always comes back to one question: how much does your fully loaded pack actually weigh? Not your base weight, not the number on the manufacturer’s website, but the real total with food, water, and everything else on trail. Weigh your pack before you choose, because the scale never lies.

If you carry 35 pounds or more, are new to backpacking, or tackle extended trips and winter routes, go with a frame pack. The Gregory Baltoro Pro delivers premium suspension comfort for heavy loads, while the Osprey Exos 58 offers an exceptional lightweight frame option for the 25 to 35 pound range. The Teton Outfitter 4600 provides budget-friendly framed support for beginners.

If your total weight stays under 25 pounds, you have compressible gear, and you know how to pack, a frameless design rewards you with freedom and weight savings. The Granite Gear Crown 3 60L is one of the best pure frameless packs available. And if you want maximum flexibility, consider a hybrid pack with removable stays that adapts to changing trail conditions.

The best pack is the one that matches your actual hiking, not your aspirational hiking. Buy for the trips you take in [cy], not the ultralight fantasy you might reach someday. Your shoulders and hips will thank you for the honesty.

I am a fish enthusiast and have been for the last 10 years. I own aquariums and love to educate, inform, and entertain on anything related to fish or aquatic life. The mission is to teach people about all sorts of exotic species from other countries as well as popular ones here in America!
