The open water is wild, unpredictable, and shared with powerful motorized watercraft. If you are swimming in a dark lake or the ocean wearing a black wetsuit and a dark swim cap, you are practically invisible. To a speeding jet ski or a motorboat, a swimmer’s head bobbing in the chop looks exactly like a small piece of floating debris.
According to organizations like the Outdoor Swimming Society, visibility is the single most important factor in open water survival. This is why investing in an Open Water Swim Buoy (often called a tow float) is absolutely non-negotiable. It acts as a blazing neon beacon, alerting everyone on the water to your exact location.
Beyond safety, modern swim buoys serve as incredible multi-tools. They allow you to safely store your car keys while you swim, carry hydration and swimming nutrition for long marathon efforts, and provide a convenient place to rest if you get a calf cramp. At OpenWaterGoggles.com, we have tested the top-rated buoys on the market to ensure they don’t cause drag or leak. Here are the 5 best open water swim buoys of 2026.
1. Best Overall & Most Trusted: New Wave Swim Buoy
If you attend any major triathlon or local open water swimming club, you will see a sea of New Wave Swim Buoys. They are the undisputed gold standard in the industry.
Why It Dominates:
The New Wave Swim Buoy is incredibly durable, constructed from high-quality PVC that resists punctures from sharp rocks on the beach. It provides a massive amount of buoyancy—more than enough to support a full-grown adult who needs to take a 60-second break to clear their mirrored swim goggles or adjust their cap.
The Dry Bag Feature:
It features an excellent roll-top dry bag compartment. You can easily fit a small towel, your smartphone, and your car keys inside. It rolls down tightly, creating a 100% waterproof seal before you inflate the dual air chambers.

2. Best for Long-Distance Swimmers: Zone3 Hydration Swim Buoy
If you are training for a 10k or an Ironman, you cannot survive without hydration. But stopping to tread water and dig through a standard dry bag is exhausting and breaks your rhythm.
Why It Dominates:
The Zone3 Hydration Swim Buoy is an engineering marvel. It features a specialized external slot specifically designed to hold a standard cycling water bottle or hydration flask. The bottle sits on the outside of the buoy, meaning you don’t have to open the waterproof compartment to get a drink. You simply roll onto your back, grab the bottle, take a swig, and keep swimming.
This simple feature drastically improves your efficiency and ensures you never skip your mid-race electrolytes.

3. Best Budget/Minimalist: XTERRA High-Vis Tow Float
Not everyone needs to carry their shoes and a towel across a lake. If you just want maximum visibility with zero extra bulk, the XTERRA Tow Float is the perfect minimalist weapon.
Why It Dominates:
This is a pure tow float—meaning it does not have a dry bag compartment. Because it doesn’t have the extra heavy-duty roll-top fabric, it is incredibly lightweight and packs down to the size of a pair of socks. Once inflated, it floats high above your legs, creating absolutely zero hydrodynamic drag.
It is the perfect, budget-friendly addition to your triathlon wetsuit setup.

4. Best for Phone GPS Tracking: Naturehike Waterproof Swim Buoy
If you use top swim apps like Strava or MySwimPro on your smartphone to track your GPS route, you need a way to bring your phone with you safely.
Why It Dominates:
The Naturehike buoy features an external, transparent, waterproof window. You can slide your smartphone into this clear pocket, allowing the GPS signal to connect directly to the satellites without being muffled by the water or thick PVC layers. You can even check your distance or tap the screen through the plastic window while treading water.

5. Best for Rough Ocean Swims: BUDDY SWIM Ultimate Safety Buoy
When you are tackling heavy surf, strong cross-currents, or massive swells, you need a buoy that won’t flip over or get ripped off your waist.
Why It Dominates:
The BUDDY SWIM features an ultra-heavy-duty nylon-coated PVC construction and a dual-airbag system. If one chamber accidentally punctures, the second chamber ensures the buoy stays afloat. The waist belt is significantly wider and more robust than standard models, ensuring it won’t chafe your hips during a grueling two-hour ocean battle.

The Final Verdict: Don’t Be a Statistic
There is absolutely no excuse to swim in the open water without a safety buoy. It does not slow you down, it does not interfere with your stroke, and it could quite literally save your life by making you visible to a passing boat.
If you want the best all-around dry bag, pick up the New Wave Swim Buoy. If you are going long, grab the Zone3 Hydration Buoy. Strap it to your waist, pull down your open water goggles, and swim with total peace of mind.
Is a swim buoy a life-saving device (PFD)?
No. A swim buoy is designed to make you visible to boaters and provide a small amount of buoyancy if you need to briefly rest or fix your goggles. It is NOT a certified Personal Flotation Device (PFD) and will not save you if you fall unconscious.
Does a swim buoy slow you down or create drag?
Surprisingly, no. Premium swim buoys are designed to float directly above your thighs, resting entirely on the surface wake created by your body. You will barely feel it towing behind you, and it will not interfere with your flutter kick.
Can I store my car keys and phone in a swim buoy?
Yes! Many high-quality swim buoys feature a roll-top ‘dry bag’ compartment. However, we always recommend placing electronic devices inside an additional waterproof Ziploc bag or phone pouch before putting them into the buoy, just to be safe.
What color swim buoy is the most visible?
Neon orange, bright pink, and high-visibility yellow are the best colors. They sharply contrast with the dark blues and greens of lakes and oceans, making you highly visible to jet skis, paddleboarders, and rescue boats.
