Simple: grab the pull-through handle to turn inside-out and reconfigure.
Tough: built in PVC-free TPU with welded seams for lightweight longevity.
Visible: neon swim buoy side, with reflective strips and accessory attachment points.
Secure: adjustable fit with extra-long waistband to suit all body shapes and sizes.
Low drag: adjustable tether to optimise tow position and reduce kicking interference.
Dry storage: waterproof internal compartment protects essentials while you swim.
Quick access: exterior mesh pocket keeps wet-use items close at hand.
Emergency-ready: integrated whistles on both tow-float and backpack sides.

Reverse backpack so blue is inside, with yellow swim buoy exterior.
Place essential items within blue internal chamber.
Roll top down tightly to marked ‘roll area’, before clipping ends together at front.
Blow to inflate both chambers, then tighten valves.

This is not a lifesaving device and should only be used by competent swimmers.
Do not lean on the swim buoy as a resting aid to prolong your swim – doing so makes you less visible in the water. If you are tired, head back in.
Ensure you roll the swim buoy closure tightly before entering the water.
To guarantee waterproof protection, place valuables inside a secondary dry bag.

2-in-1 Reversible Tow Float Backpack

One smart solution, from shore to swim and back again

Reversible Tow Float Backpack: TPU Construction

TPU (thermoplastic polyurethane) is a major step up from the standard PVC used for traditional swim floats. It’s lighter, more flexible and more abrasion-resistant, so our 2-in-1 Reversible Tow Float Backpack handles frequent use in the water and rough treatment on the shore without failing. Welded seams keep the dry compartment secure, while the soft-touch finish feels smooth and tactile. Plus PVC-free TPU avoids the harmful plasticisers used in PVC and releases fewer toxic chemicals during production and disposal. The result is a much tougher, longer-lasting product with a more responsible material at its core.

Reversible Tow Float Backpack: Reversible Design

Our innovative flip-through configuration is what makes the 2-in-1 Reversible Tow Float Backpack unique. It’s a refined waterproof backpack to carry what you need to the swim spot. Then pull it inside-out to reverse the compartments, and inflate both chambers to turn it into a high-vis tow float with dry storage inside. After your swim, it reverts back to a dry backpack to carry wet kit home again. The pull-through handle makes the whole process quick and easy. This dual-purpose design solves some familiar swimmer frustrations: too many bags, extra hassle, and nowhere to keep essentials while you swim.

Reversible Tow Float Backpack: Adjustable Tow System

A good tow float must stay visible without compromising your swim. Our 2-in-1 Reversible Tow Float Backpack uses an adjustable tether to help reduce drag and kicking interference, so it tows comfortably behind you instead of constantly disrupting your stroke. The extra-long adjustable waistbelt is designed to securely fit a broad range of body shapes and sizes, so it’s easy to personalise, ensuring every swimmer can achieve a secure attachment. Together, the tether and waistband create a more comfortable, confidence-boosting tow set-up that feels completely dependable yet as unobtrusive as possible.

FAQ - Reversible Swim Buoy Backpack

A swim buoy backpack is a dual-purpose swimming accessory that combines a waterproof backpack with an inflatable swim buoy. It allows open-water swimmers to carry kit to the shore, then convert the bag into a high-visibility swim float with dry storage for essentials while swimming.

The swim buoy backpack uses an innovative pull-through reversible design. Before your swim, simply turn the backpack inside-out so the high-vis swim buoy side faces outward, place essentials inside the waterproof chamber, roll and secure the closure, then inflate both chambers. After swimming, it reverses back into a comfortable backpack for carrying wet kit home.

For a step-by-step guide, including tips on packing, inflating and switching between backpack and swim buoy modes, read our blog: How To Use The 2-in-1 Reversible Swim Buoy Backpack

Yes. The internal dry compartment is designed to keep essentials protected while you swim, including items like footwear, a towel, keys, snacks, and spare layers. For valuables such as phones or wallets, we recommend using an additional dry pouch for complete protection.

The dry storage compartment is highly water-resistant thanks to welded seams and a roll-top closure. When sealed correctly, it protects your kit from splashes, rain, and water exposure during swims. As with any dry bag, electronics and valuables should be placed inside a secondary waterproof pouch for maximum protection.

A properly designed swim buoy should create minimal drag in the water. The Reversible Swim Buoy Backpack uses an adjustable tether system that helps optimise tow position and reduce interference while swimming, allowing the float to track comfortably behind you.

Tow floats help improve visibility in the water, making swimmers easier to spot by boats, paddleboarders, lifeguards, and other water users. They also provide convenient waterproof storage for essentials during point-to-point swims, training sessions, and adventure swims.

Yes. The dual-purpose design is particularly useful for adventure swimming, point-to-point routes, and longer open-water sessions where you may need to carry extra kit, nutrition, footwear, or layers with you while swimming.

Unlike standard swim buoys, which are designed primarily for visibility in the water, the Reversible Swim Buoy Backpack is an innovative 2-in-1 solution that combines a waterproof backpack with a high-vis swim buoy dry bag. Its unique reversible design allows you to carry your kit comfortably to the water, then transform it into a swim buoy with 19L of waterproof storage for essentials while you swim. After your session, it reverses back into a backpack to carry wet gear home, reducing the need for multiple bags and making adventure swimming simpler and more convenient.

Want to know how the idea came to life? Read our Meet the Designer blog to discover the thinking behind the Reversible Swim Buoy Backpack and the features that make it unique.

Standard dry bags are not designed to function safely as swim buoys. The Reversible Swim Buoy Backpack is specifically engineered for swimming, with dual inflation chambers, high-visibility materials, reflective detailing, an adjustable tow system, and secure waist attachment.

Yes. The tow system includes an extra-long adjustable waistband designed to comfortably fit a wide range of body shapes, sizes, and layering choices. The tether is also adjustable so you can have it as long or short as you would like to depend on leg length or swimming style.

Yes. It’s suitable for year-round open-water swimming, including cold-water sessions, training swims, and outdoor adventures. The waterproof storage is useful for carrying warm layers, footwear, and post-swim essentials.

No. Swim buoys are designed to improve visibility and carry essentials, not as lifesaving or flotation devices. Swimmers should not rely on the float for resting or buoyancy support in the water.

The Reversible Swim Buoy Backpack offers an ample 19L of waterproof storage in swim buoy mode and 28L in backpack mode. This is perfect for holding essentials for your time both in and out of the water, such as footwear, layers, a towel, and nutrition.

The Reversible Swim Buoy Backpack features an adjustable waistband and tether system which fits a range of body shapes and sizes. You can also customise the fit to ensure the backpack is comfortable when worn with clothing, a swimsuit, a wetsuit, or additional layers.

A swim buoy is not mandatory for open water swimming, but it is highly advisable that you do use one. A swim buoy ensures that you are visible to other water users, and the backpack element of the Reversible Swim Buoy Backpack also offers convenient dry storage.

"Having one piece of equipment that works as both a backpack and a tow float means there's no need to carry multiple bags or extra weight."

Great bag

Really great pack. I had 2 flimsy bags that both got holes in them. This one is very sturdy and I think it would take a lot to puncture it. I only with the straps were removable because they take up a lot of room inside the buoy option and make it hard to find what you're looking for. I've started putting my items in a plastic bag and then into the buoy so I can just pull everything out at once. It does fit a lot of stuff i take a towel, sunglasses, sunscreen, phone, water, book and a snack. I kike to swim out to a little island near my place to read and tan alone and this is a perfect bag to do that!

Tow float bag

This bag is great for taking stuff to swims - wide straps to prevent chaffing when using on bike on a hot day with no sleeves on. Lots of room for kit and the mesh pocket on the float side is great for my waterproof camera.

Top bag

So I bought this bag because it serves 2 purposes. 1 a dry bag to stash my stuff with me and 2. It identifies where I am. The bag is fairly easy to reverse, easy to inflate and has enough room to store the valuables. I have a Red phone cover which I attach to the loops and store in the mesh pocket so I can easily use it out in the water.

Practical, creative and convenient.

Great tow float. So nice not to have to worry about leaving your stuff on the beach, and being able to turn it into a back pack makes it easy to carry after. Hopefully intend to do some swim/walks in the future.

Tip- put everything in a plastic bag so you can take everything out in one go and put on any surface to reverse the float/backpack is easier than putting individual items on the sand.

Also comforting to know you can exit the water at any point if conditions change and not have to walk back to a bag.
