6 Best Tow Floats For Carrying Water Bottles For Swimmers

There is nothing quite like the freedom of an open-water swim, but staying hydrated while miles from the shore presents a unique logistical challenge. A tow float is no longer just a safety tether; it has evolved into a vital floating locker for your water bottle and nutrition. Choosing the right vessel ensures you can push your distance limits without sacrificing your health or safety.

Essential Gear: Safety Benefits of Tow Floats

A tow float serves as your primary beacon in the water, making you highly visible to boaters, jet skis, and fellow water users. By tethering a brightly colored, inflatable buoy to your waist, you significantly reduce the risk of accidental collisions, especially in choppy or low-light conditions. It is the single most effective piece of gear for passive safety in open water.

Beyond visibility, these floats provide an immediate point of buoyancy should you experience a cramp or sudden fatigue. If you need a moment to catch your breath, you can simply lean on the float to stay afloat without expending extra energy. It acts as a reliable safety net that allows you to focus on your stroke mechanics rather than worrying about the unexpected.

Choosing the Right Tow Float for Hydration Needs

When selecting a float for hydration, prioritize accessibility and volume. You need a design that allows you to reach your bottle without having to deflate the unit or struggle with complicated clips while treading water. A dedicated dry bag compartment or an external mesh sleeve are the gold standards for keeping your water secure yet reachable.

Consider the buoyancy-to-weight ratio of your gear. If you are carrying a large water bottle, ensure the float has enough displacement to stay high on the water surface rather than dragging behind you like an anchor. A well-balanced float should feel like an extension of your body, creating minimal drag while keeping your supplies bone-dry and organized.

New Wave Swim Buoy: Best for Long Distance Swims

The New Wave Swim Buoy is the gold standard for marathon swimmers who need a reliable, high-visibility companion. Its dual-chamber design provides excellent buoyancy, and the generous dry bag compartment easily accommodates a large water bottle alongside extra nutrition. It is built to withstand hours in the water without losing air pressure.

If you are training for long-distance events where you cannot afford gear failure, this is your go-to choice. Its streamlined shape cuts through the water efficiently, ensuring it doesn’t interfere with your kick rhythm. For the serious distance swimmer, this buoy is the most dependable investment you can make.

Phelps Dry Bag Buoy: Top Choice for Gear Storage

The Phelps Dry Bag Buoy excels in versatility, offering a robust storage solution for those who carry more than just a water bottle. Its construction is exceptionally durable, capable of protecting sensitive items like keys, phones, and hydration packs from moisture. The secure roll-top closure ensures that even in rough surf, your gear remains perfectly sealed.

This buoy is ideal for the swimmer who treats their swim as an excursion rather than just a workout. If you need to transport extra gear to a secluded beach or island, the storage capacity here is unmatched. Choose this if you prioritize security and storage volume over ultra-lightweight performance.

ISHOOT Swim Tow Float: Best for Hydration Access

The ISHOOT Swim Tow Float stands out for its clever design that prioritizes rapid hydration. Unlike standard dry bags that require you to stop and fumble with clips, this model often features external configurations that keep your bottle ready for a quick sip. It is designed specifically for the swimmer who needs to stay hydrated without breaking their flow.

This float is perfect for interval training or shorter, high-intensity sessions where you want to grab a drink and get back to your pace immediately. The build is lightweight and unobtrusive, making it feel almost invisible during your swim. If your primary goal is seamless hydration access, this is the most practical tool on the market.

The Friendly Swede Buoy: Best Durable Option

The Friendly Swede is widely recognized for its heavy-duty construction, utilizing high-quality PVC that resists abrasions from rocks and sand. This is a "set it and forget it" piece of equipment that handles the wear and tear of frequent lake or ocean use with ease. It is a fantastic option for those who swim in unpredictable or rugged environments.

While it is slightly heavier than minimalist options, the trade-off in durability is well worth it. You won’t have to worry about pinhole leaks or strap failures after a few months of heavy use. For swimmers who frequent rocky entry points or rough coastal waters, this is the most resilient choice available.

Cressi Swim Safety Buoy: Best Lightweight Pick

If you prefer a minimalist approach, the Cressi Swim Safety Buoy is an excellent, low-profile option. It is incredibly lightweight and creates almost zero drag, making it perfect for competitive swimmers who want safety without the bulk. It provides just enough space for a small, slim water bottle or a hydration soft-flask.

This buoy is best suited for pool-to-open-water transitions or calm lake swims where you don’t need to carry a significant amount of gear. It keeps you visible and safe without feeling like you are towing a piece of luggage. This is the clear winner for the swimmer who wants maximum speed and minimal equipment interference.

Wild Swim Dry Bag: Best for Bulkier Accessories

The Wild Swim Dry Bag is designed for the adventurer who needs to carry a bit more, such as larger water bladders, goggles, or even a dry towel for post-swim comfort. The internal capacity is spacious, and the robust strap system keeps the bag centered behind you to prevent side-to-side swaying. It is a workhorse of a float.

Because of its size, it is slightly more noticeable in the water, but it provides unmatched utility for longer outings. If your swim involves a destination—like swimming to a café or a distant bay—the ability to carry extra gear is invaluable. This is the best choice for the "adventure swimmer" who needs a mobile locker.

Proper Packing Tips for Your Hydration Supplies

Always pack your water bottle in the center of the dry bag to maintain a balanced center of gravity. If the weight is off-center, the float will tilt, increasing drag and potentially causing the strap to chafe against your hip. Use a soft, reusable flask if possible, as it conforms to the shape of the bag better than a rigid plastic bottle.

Ensure that your hydration container is completely sealed before placing it inside the float. Even in a waterproof bag, a leaky bottle can compromise your other gear, like electronics or dry clothes. Always double-check your roll-top closure, ensuring at least three full folds to create a watertight seal.

Maintenance and Care for Your Tow Float Gear

After every swim, rinse your tow float thoroughly with fresh water to remove salt, chlorine, or lake sediment. These substances can degrade the PVC material and weaken the straps over time. Once rinsed, allow the float to air dry completely in a shaded area, as prolonged exposure to direct sunlight can cause the material to become brittle.

Store your float in a cool, dry place, ideally partially inflated or laid flat to prevent creases from forming in the material. Check the tether and buckle system before every session for signs of fraying or stress. Taking these small steps will ensure your float remains a reliable safety partner for many seasons to come.

Investing in a quality tow float is the smartest way to balance your performance goals with essential safety requirements. By selecting the right model for your specific hydration needs, you can swim with confidence and comfort in any body of water. Stay visible, stay hydrated, and enjoy every stroke of your open-water journey.
