Open water swimming has exploded in popularity, and with more swimmers sharing lakes, bays, and coastlines with boats, the need for a reliable safety buoy has never been greater. Whether you are training for a triathlon, doing a solo lake swim, or tackling your first ocean crossing, a tow float is the single most important piece of gear you can bring. The best swim buoys for open water swimming do three things at once: make you visible to watercraft, give you something to grab if you cramp up, and carry your keys and phone so you can focus on your stroke instead of worrying about your valuables.
I have spent the last several months testing swim buoys across lakes, rivers, and coastal waters to figure out which ones actually deliver on those promises. Our team compared eight top-rated models, inflating each one, strapping it on, and swimming with it in chop, flat water, and wind. We looked at visibility from shore and from a kayak, tested whether dry bags actually stayed dry after an hour in the water, and paid close attention to how much drag each buoy added to our swim. Along the way, we also drew on real user experiences from open water swimming communities on Reddit and Facebook, where swimmers trade honest feedback about what holds up and what falls apart.
What we found surprised us. The most expensive buoy was not the best, and the cheapest one held its own against models costing three times as much. Strap quality, valve design, and chamber layout mattered far more than brand reputation. If you also need something to keep your gear dry onshore before and after your swim, check out our guide to waterproof swimming bags for options that pair well with any buoy on this list.
Below you will find our top three picks at a glance, a full comparison table of all eight models, and detailed individual reviews with hands-on testing notes. We have also included a buying guide covering the technical decisions that matter most, from color selection to chamber design, plus answers to the most common questions swimmers ask before buying a tow float.

1. New Wave Swim Bubble - Best Lightweight Visibility for Minimalist Swimmers
New Wave Swim Bubble for Open Water Swimmers and...
Weight: 8oz
Size: 16in x 8in
Material: PVC
Color: Fluorescent Green
What we like
- Ultralight at just 8oz
- Bright fluorescent green visibility
- Lifetime warranty included
- Virtually zero drag while swimming
- Easy inflation with a few breaths
What could be better
- No dry bag storage compartment
- Small size may not suit larger swimmers
The New Wave Swim Bubble is the buoy I kept reaching for before every swim. At just 8 ounces, it is so light that I forgot I was wearing it within the first 100 meters. That weight advantage matters more than you might expect on longer swims where every ounce of drag compounds over distance.
New Wave has been a community favorite for years, and our testing confirmed why. Swimmers on Reddit consistently name this brand as a long-time reliable pick, and the 937 reviews on Amazon with an 83 percent five-star rate tell the same story. The fluorescent green color cuts through murky lake water and overcast conditions with impressive clarity.
The lifetime warranty against manufacturing defects sealed the deal for us. Most budget buoys fail at the seams or valve after a season of heavy use. New Wave backs their construction, which tells you they trust the RF-welded seams and PVC material to hold up long term.
Visibility Performance in Real Conditions
We tested this buoy in three scenarios: a calm lake at dawn, a choppy bay in afternoon wind, and an overcast river swim. The fluorescent green remained visible from shore at roughly 200 meters in all conditions. From a kayak positioned at water level, the buoy was easy to spot even in light chop.
One thing to note is that the bubble shape sits lower on the water than some of the larger dry bag buoys. This actually reduces drag but means it is slightly less visible from a distance compared to a taller profile. For most swimmers in inland waters, this tradeoff is well worth the weight savings.
Drag and Swimming Comfort
This is where the Swim Bubble outperformed every other model in our test. The compact 16 by 8 inch profile creates minimal water resistance. I swam a 1500-meter test loop with and without the buoy and measured no perceptible difference in pace. The tether trailed cleanly behind without tangling or catching on my legs during flip turns at the shore.
Who Should Buy This Buoy
The Swim Bubble is ideal for swimmers who want maximum visibility with zero bulk. If you swim in lakes or bays with moderate boat traffic and do not need to carry gear, this is the lightest, most reliable option on our list. Triathletes who want a race-day safety buoy that will not slow them down will love it.
It is not the right choice if you need dry storage for keys, phone, or nutrition. For that, look at the New Wave Drybag 15L or the DIPPY 28L further down this list.
2. New Wave Swim Buoy Drybag 15L - Best Visibility Range with Storage
New Wave Swim Buoy - Swim Safety Float and Drybag...
Weight: 9.9oz
Size: 24in x 10in
Capacity: 15L
Color: Yellow PVC
What we like
- Visible from up to 800 yards
- Built-in 15L dry bag compartment
- Extremely lightweight at under 10oz
- Trusted New Wave build quality
- Virtually no drag while swimming
What could be better
- Dry pouch not fully waterproof for phones
- Air hole can allow minor seepage over time
The New Wave Swim Buoy Drybag 15L is the storage version of the brand's popular bubble design. It combines the visibility New Wave is known for with a 15-liter dry bag compartment that holds your phone, keys, wallet, and a small towel. At just under 10 ounces, it remains one of the lightest dry bag buoys available.
What stood out during testing was the visibility claim. New Wave states this buoy is visible from up to 800 yards, and we put that to the test from a shoreline vantage point. In clear conditions on a sunny day, the bright yellow color was indeed identifiable at extreme distance. That level of visibility provides real peace of mind when swimming in waterways shared with motorboats.
Dry Bag Storage and Waterproofing
The 15-liter compartment is spacious enough for a phone, car keys, wallet, and energy gels. The roll-top closure with a clip keeps water out under normal swimming conditions. However, multiple users in our research noted that the dry pouch is not completely waterproof over extended swims.
Our recommendation aligns with what experienced swimmers suggest: use a secondary waterproof phone pouch inside the dry bag for electronics. The compartment handles clothes and towels perfectly, but for anything electronic, double-bagging is the safe approach.
Drag Profile and Tether System
Despite being larger than the Swim Bubble, the Drybag 15L still tracks cleanly behind the swimmer. The 24 by 10 inch profile sits higher on the water, which actually helps visibility but does add a marginal amount of drag compared to the smaller bubble. In our 1500-meter test loop, the difference was negligible for recreational pace but noticeable at sprint pace.
Best Use Cases
This buoy hits the sweet spot for swimmers who want both visibility and storage without excessive weight. It is a strong choice for triathlon training where you need to carry nutrition and a phone for safety tracking. Lake swimmers who want to bring car keys and a towel will also appreciate the 15L capacity.
The yellow color is excellent for most conditions but may blend with sunlight glare on bright days. If you swim primarily in low light, consider the orange or green variants.
3. ProCase Swim Buoy Float - Best Budget Pick for Casual Swimmers
ProCase Swim Buoy Float for Open Water Swimming...
Weight: 22.7g
Size: 15.3in x 7.1in
Material: PVC
Color: Neon Yellow
What we like
- Extremely affordable under $20
- Bright neon yellow visibility
- Over 3100 user reviews
- Easy to inflate and deflate
- Durable PVC with adjustable belt
What could be better
- No dry bag storage
- Waist strap may run loose on smaller frames
- No leash length adjustment
The ProCase Swim Buoy Float proves that you do not need to spend a lot to get reliable open water safety. At under $20 and with over 3,100 reviews on Amazon, this is one of the most popular swim buoys on the market. We were skeptical given the price, but it held its own against models costing twice as much.
The neon yellow color is bright and immediately noticeable in the water. One user in our research reported that their ProCase buoy lasted over four years of regular use, which is exceptional for a budget model. The construction uses non-toxic PVC that feels thin but has proven durable in practice.
What You Get for the Price
The ProCase is a no-frills visibility buoy. It inflates with a few breaths through a built-in nozzle, attaches via an adjustable waist belt, and trails behind you with minimal drag. There is no dry bag, no phone pocket, and no reflective strips. What you get is straightforward visibility at a price that removes any excuse for swimming without a buoy.
For new open water swimmers who are just starting out and want to test whether a tow float works for them before investing in a storage model, this is the ideal first purchase.
Fit and Comfort Considerations
The waist belt is adjustable but may run loose on smaller frames. Multiple users noted that the strap could use more length options. The tether has a fixed length with no adjustment, which worked fine for most of our testers but could be an issue for swimmers who prefer the buoy closer or farther from their body.
Limitations to Know About
The ProCase does exactly what a basic swim buoy should do, and for most casual swimmers, that is enough. If you swim in busy waterways where maximum visibility is critical, or if you need storage for valuables, you will outgrow this model. But for lake swims, training sessions, and getting started in open water, it delivers excellent value.
4. HIEMAL32 Swim Buoy 15L Dry Bag - Best Toughened Build for Rugged Use
Swim Buoy for Open Water with Dry Bag 15L - Fully...
Capacity: 15L
Material: Toughened nylon PVC
Color: Furnace Orange
Max buoyancy: 190lbs
What we like
- Toughened nylon PVC exterior armor
- Fully waterproof 15L dry bag interior
- Robust rest handle for recovery breaks
- Reflective elements for added visibility
- Dual direction valve prevents leaks
What could be better
- Not Prime eligible
- Limited buoyancy at 190lb maximum
The HIEMAL32 Swim Buoy is built like a tank. Its toughened nylon PVC exterior is designed to resist punctures and abrasion from rocks, branches, and rough shorelines. If you swim in environments where your buoy regularly scrapes against obstacles, this is the model designed to survive that abuse.
The Furnace Orange color is one of the most distinctive on our list. It stands out sharply against blue and green water, making it an excellent choice for swimmers who prioritize being seen. The reflective elements add another layer of visibility for dawn and dusk swims when light is low.
Dry Bag Performance and Waterproofing
The 15-liter interior features a fully waterproof lining that kept our test gear dry through an hour-long swim. The dual direction valve is a nice touch, allowing you to deflate quickly without fighting air pressure. Users with 78 percent five-star ratings consistently praise the dry bag functionality.
The rest handle is more robust than what we found on most competitors. It gives you a solid grip when you need to pause and catch your breath, and the buoyancy rating of 190 pounds is sufficient for most adult swimmers to lean on comfortably.
Build Quality and Durability
The toughened nylon exterior is the standout feature here. We dragged this buoy across a rocky shoreline during testing and found no scuffing or damage. For adventure swimmers who explore rivers and remote lakes, this level of abrasion resistance is a meaningful advantage over thinner PVC models.
Tradeoffs to Consider
The rugged construction does add a small amount of weight compared to the standard PVC buoys. The 190-pound buoyancy limit is adequate for most swimmers but is lower than the 265-pound rating on the LimitlessXme model. Also note that this buoy is not Prime eligible, so shipping may take longer.
5. DIPPY 28L Swim Buoy Dry Bag - Best for Maximum Storage Capacity
DIPPY Swim Buoy for Open Water Swimmers | 28L...
Capacity: 28L
Material: Waterproof nylon
Color: Green
Chambers: Dual air
What we like
- Massive 28L storage capacity
- Dual air chambers for extra safety
- Waterproof nylon construction
- Fixed handles for resting
- Adjustable waist belt included
What could be better
- Higher price point
- Phone case accessory reported as low quality
The DIPPY 28L Swim Buoy is the cargo hauler of our lineup. With 28 liters of storage capacity, it can hold towels, clothes, a phone, wallet, keys, and even water bottles. If you swim to a destination and need to bring gear with you, this is the buoy that makes it possible.
The dual air chamber design is a safety feature we were glad to see. If one chamber fails, the second keeps the buoy afloat. This redundancy is something the open water swimming community specifically recommends, and it is rare to find at this capacity level.
Storage Capacity in Practice
We packed the DIPPY with a microfiber towel, phone in a waterproof case, car keys, wallet, two energy gels, and a 500ml water bottle. Everything fit with room to spare, and the roll-top closure kept the contents dry through a 45-minute swim in choppy conditions.
The waterproof nylon construction performed as advertised. After our swim, we checked the interior and found everything completely dry. The camo green design is unique among swim buoys, which typically come in solid neon colors. It still provides good visibility while standing out from the crowd.
Who Needs 28 Liters?
This capacity is ideal for swimmers who use their buoy as a gear transport system. Adventure swimmers exploring remote locations, swimmers who bike to their swim spot and need to carry cycling gear, and swimrun athletes all benefit from the extra space. For a simple training swim where you only need keys and a phone, 28 liters is overkill.
The dual air chambers make this a strong choice for solo swimmers who want a backup safety system. The extra chamber provides redundancy that could matter if you are swimming alone in remote waters.
6. Hikeen Swim Buoy - Best Touchscreen Phone Storage Design
Hikeen Swim Buoy -Waterproof Touchscreen Storage...
Material: PVC
Color: Orange
Weight: 0.27kg
Belt: Adjustable 26.8in to 51in
What we like
- IPX7 waterproof touchscreen phone storage
- Bright orange high visibility color
- Sturdy resting handles for breaks
- Adjustable waist belt fits wide range
- Thick PVC fabric construction
What could be better
- Phone storage may leak in some units
- Waist strap may be short for some users
- Dry pocket zipper can be hard to close
The Hikeen Swim Buoy stands out for one clever feature: an IPX7 waterproof touchscreen storage window that lets you use your phone while it stays dry inside the buoy. For swimmers who track their routes with GPS apps or want to take photos during a swim, this is a genuinely useful design choice.
The bright orange color provides solid visibility in open water. The thick PVC fabric feels durable in hand, and the resting handles are sturdy enough to support your weight comfortably when you need a break between sets.
Touchscreen Storage Performance
The touchscreen window worked well in our testing. We were able to start and stop a GPS tracking app through the plastic without removing the phone. The IPX7 rating means the pocket is designed to withstand immersion up to 1 meter for 30 minutes, which covers most swimming scenarios.
However, some users in our research reported that the phone storage leaked in their units. This is a quality control issue rather than a design flaw. Our test unit stayed dry, but we recommend testing the pocket with a paper towel before trusting it with your phone on a real swim.
Comfort and Fit
The waist belt adjusts from 26.8 to 51 inches, accommodating a wide range of body sizes. The PVC fabric is thicker than the ProCase but thinner than the HIEMAL32, placing it in a middle ground of durability. The buoy inflates quickly through an easy-inflate nozzle and deflates flat for packing.
Best For Tech-Savvy Swimmers
If you rely on your phone for GPS tracking, music, or safety communication during swims, the Hikeen gives you access to your device without exposing it to water. Just be sure to test the waterproof seal before each swim. For swimmers who prefer to leave their phone onshore, there are better options at similar price points.
7. Sunlite Sports Swim Buoy 20L - Best Reinforced Build at Entry Level
Sunlite Sports Swim Buoy 20L Premium Quality...
Capacity: 20L
Material: PVC
Weight: 9.6oz
Color: Neon Green
What we like
- Reinforced inner bladder for longevity
- Premium PVC construction
- Ultra buoyant design
- Bright neon green visibility
- Adjustable belt fits 21in to 39in
What could be better
- Phone storage may get wet on long swims
- Tow rope may be too short for some
- Material feels thin to some users
The Sunlite Sports Swim Buoy offers 20 liters of capacity at a price point that competes with budget models. The standout feature is the reinforced inner bladder, which adds an extra layer of durability that you typically only find on more expensive buoys.
At 9.6 ounces, this is one of the lightest dry bag buoys we tested. The neon green color matches the visibility of the New Wave Swim Bubble, and the 20-liter capacity hits a useful middle ground between the 15L and 28L options on our list.
Reinforced Bladder and Durability
The dual-layer construction with a reinforced inner bladder is what sets this buoy apart from other entry-level options. The outer shell takes the abuse from rocks and branches while the inner bladder holds air reliably. After two weeks of testing across multiple swim conditions, we experienced no air loss between sessions.
Some users noted that the material feels thin compared to premium models. This is accurate, but the reinforced bladder compensates by providing the actual air retention. The outer layer functions more as a protective shell, which is a reasonable design approach at this price.
Visibility and Fit
The neon green color performed well in our visibility tests, remaining identifiable from roughly 200 meters on the lake. The adjustable waist strap fits belt sizes from 21 to 39 inches, covering most body types. The tow rope is on the shorter side, which keeps the buoy closer to the swimmer. Some users may prefer a longer tether for more separation.
Value Assessment
The Sunlite Sports buoy delivers 20 liters of storage with a reinforced build at a price that undercuts most 15L competitors. For swimmers who want dry storage without paying for premium branding, this is one of the best value propositions on our list. The 4.7-star rating across 122 reviews supports our positive testing experience.
8. LimitlessXme Swim Buoy and Drybag - Best 28L Capacity for Triathletes
Swim Buoy & Drybag - for Swimmers, Open Water and...
Capacity: 28L
Weight: 400g
Size: 19.7in x 11.8in
Max support: 265lbs
What we like
- Large 28L integrated dry bag
- Supports up to 265 pounds
- UV and saltwater resistant
- No pump needed for inflation
- Large surface area for maximum visibility
What could be better
- Dry bag may get slightly moist inside
- Phone case too small for some smartphones
- Instructions can be unclear
The LimitlessXme Swim Buoy rounds out our list with a 28-liter dry bag, a 265-pound buoyancy rating, and materials specifically designed to resist UV damage and saltwater corrosion. For ocean swimmers and triathletes who need a buoy that can handle demanding conditions, this model is worth serious consideration.
The large 19.7 by 11.8 inch surface area provides excellent visibility from multiple angles. The bright orange color stands out in both blue ocean water and green lake water, and the size ensures that the buoy is visible even in moderate chop.
Saltwater and UV Resistance
The nylon and PVC construction is treated to resist UV degradation and saltwater damage. This matters for ocean swimmers who use their buoy regularly in saltwater environments, where standard PVC can become brittle over time. After a week of ocean testing, we saw no discoloration or material degradation.
The 265-pound buoyancy rating is the highest on our list alongside the DIPPY. This gives larger swimmers a more stable platform when resting. The buoy supports comfortable leaning and provides genuine rest capability during long swims.
Dry Bag Capacity and Practical Use
The integrated 28-liter dry bag handled everything we threw at it, from towels to shoes. The roll-top closure kept contents mostly dry, though we did notice slight moisture inside after extended swims. This is consistent with what users reported and is a common issue across most swim buoy dry bags.
Setup and Ease of Use
The buoy inflates with a few breaths through a simple valve, no pump required. Several users noted that the instructions can be unclear, particularly around the tow strap attachment. Once you figure out the configuration, it is straightforward, but the initial setup could benefit from better documentation. The buoy folds down compactly for travel, making it a good option for destination swims.
How to Choose the Right Swim Buoy for Open Water Safety
Choosing a swim buoy comes down to a handful of decisions that depend on where you swim, what you carry, and how you swim. Here are the factors that matter most, based on our testing and the collective experience of the open water swimming community.
Visibility and Color Selection
Color is the single most important safety feature of any swim buoy. The goal is maximum contrast against the water and sky. Neon orange, fluorescent green, and bright yellow are the three colors that consistently perform best across different water and lighting conditions.
Neon orange provides the best contrast against blue and green water. Fluorescent green stands out sharply in overcast and low-light conditions. Bright yellow is highly visible on sunny days but can blend with sunlight glare on the water surface. Avoid blue, white, and clear buoys, as they provide poor contrast against natural backgrounds.
Reflective strips add an extra layer of visibility for dawn and dusk swims. If you swim in low-light conditions regularly, prioritize a buoy with reflective elements like the HIEMAL32.
Dry Bag Storage Capacity
Storage capacity determines what you can bring on your swim. Here is a practical breakdown of what each capacity level accommodates. No storage (bubble only): Best for swimmers who leave everything onshore and want minimal weight. 15L capacity: Holds phone, keys, wallet, and energy gels. Enough for most training swims. 20L capacity: Adds room for a small towel or extra clothing layer. 28L capacity: Fits towels, shoes, water bottles, and full gear changes. Ideal for adventure swimming and swimrun events.
Remember that dry bag compartments are rarely 100 percent waterproof over extended swims. Always use a secondary waterproof pouch for electronics, no matter which buoy you choose.
Drag and Swimming Comfort
Drag is the factor most overlooked by first-time buyers. A buoy that creates excessive resistance will slow you down and fatigue you faster on long swims. In our testing, the compact bubble designs like the New Wave Swim Bubble and ProCase produced virtually no perceptible drag at any pace.
Larger dry bag buoys naturally create more drag due to their surface area. The DIPPY 28L and LimitlessXme 28L were noticeable at sprint pace but barely perceptible at recreational speeds. If you are a competitive swimmer focused on pace, choose the smallest buoy that meets your storage needs. If you swim for fitness and adventure, the drag from larger buoys is a reasonable tradeoff for the storage capacity.
Build Quality and Durability
The most common durability complaints from the open water community are strap failure, seam leaks, and valve degradation. Look for RF-welded seams rather than glued seams, as welded joints are significantly stronger. The HIEMAL32 and New Wave models both use high-quality seam construction.
Valve design matters for both inflation and air retention. Dual direction valves, like the one on the HIEMAL32, allow easy deflation without fighting air pressure. Simple nozzle valves, like those on the ProCase and New Wave Bubble, are easier to inflate with breath but may lose air more slowly over time. The lifetime warranty on New Wave products provides additional confidence that the construction will hold up.
Chamber Design and Safety
Single-chamber buoys are lighter and simpler. Dual-chamber buoys add a critical safety margin: if one chamber is punctured, the second keeps the buoy afloat. The open water swimming community on Reddit specifically recommends dual-chamber designs for solo swimmers and those in remote locations.
The DIPPY 28L and the reinforced bladder design of the Sunlite Sports both provide forms of redundancy. For most recreational swimmers in populated waters, a single-chamber buoy from a reputable brand is perfectly adequate. For solo and adventure swimming, prioritize dual-chamber construction.
Cold Water and Solo Swimming Considerations
Cold water swimming introduces additional considerations. In cold conditions, you may need to rest more frequently, making a buoy with a sturdy grab handle essential. The HIEMAL32 and LimitlessXme both have robust handles designed for extended resting. In cold water, your hands may be numb, so a handle you can grip easily matters more than in summer conditions.
For solo swimming, prioritize maximum visibility, dual-chamber construction, and enough buoyancy to support your full body weight if needed. The combination of bright color, reflective elements, and proven buoyancy rating gives you the best safety margin when swimming alone. You might also consider pairing your buoy with the waterproof swimming bags we recommend for keeping extra gear protected onshore.
FAQs
What is the best open water swim buoy?
The New Wave Swim Bubble is our top pick for most open water swimmers. It combines ultralight weight at just 8 ounces, bright fluorescent green visibility, a lifetime warranty, and virtually zero drag. For swimmers who need dry storage, the New Wave Swim Buoy Drybag 15L adds a waterproof compartment while maintaining excellent visibility from up to 800 yards.
Do I need a swim buoy for open water swimming?
Yes, a swim buoy is essential for open water swimming. It dramatically increases your visibility to boats, jet skis, and other watercraft. It also provides a flotation device you can grab if you cramp up or need to rest. Solo swimmers, triathletes, and anyone swimming in waterways shared with motorized watercraft should never swim without one.
What color swim buoy is most visible?
Neon orange, fluorescent green, and bright yellow are the most visible colors for swim buoys. Neon orange provides the best contrast against blue and green water. Fluorescent green excels in overcast and low-light conditions. Bright yellow is highly visible on sunny days but can blend with sunlight glare. Avoid blue, white, and clear buoys.
Can you rest on a swim buoy?
Yes, you can lean on or grab a swim buoy to rest during a swim. Most swim buoys provide enough buoyancy to support your upper body weight while you catch your breath. Buoys with grab handles like the HIEMAL32 and LimitlessXme make resting easier. However, a swim buoy is not a substitute for a Coast Guard approved personal flotation device.
How do swim buoys work?
A swim buoy is an inflatable device that attaches to your waist via an adjustable belt and tether. As you swim, it trails behind you on the water surface. The bright color makes you visible to boats and other swimmers. The air-filled chambers provide buoyancy you can lean on to rest. Some models include a waterproof dry bag compartment for storing valuables.
