Best Open Water Swim Accessories 2026
What to Look For
Open water swimming accessories serve two critical purposes: keeping you visible and safe, and improving your performance. As open water season picks up across the UK, the right kit will give you confidence, extend your training range, and make every session safer. We’ve rounded up the best options available in 2026.
Key Features to Consider
- Visibility — In open water, being seen matters. Bright-coloured tow floats and swim caps are your first line of defence against boat traffic and rescue teams looking for you.
- Buoyancy and storage — Many tow floats double as dry bags, letting you carry keys, a phone, and nutrition on longer swims. Inflation method matters — look for valves you can operate with wet hands.
- Weight and drag — A heavy or wide tow float can add noticeable drag at race pace. For training use this matters less, but for racing, opt for slim or ultralight options.
- Goggle fit and tinting — Open water goggles should seal well in all conditions. Tinted or mirrored lenses help in bright sunlight; clear lenses work better in low-light or overcast conditions.
Our Top Picks
Best Overall: Zone3 28L Swim Safety Buoy / Tow Float
Zone3’s 28-litre safety buoy is a staple of UK open water swimmers for good reason. It’s made from 100% recycled polyester, highly visible in hi-vis orange, and doubles as a dry bag with a waterproof roll-top closure. The tow leash is comfortable at the waist, and drag is minimal even at race pace. Perfect for all levels from beginners to elite open water swimmers.
Best Budget: Zone3 Ultralight Swim Bubble
If you just want a lightweight safety float without the dry bag functionality, Zone3’s Swim Bubble is an excellent lightweight choice. It inflates quickly, clips securely at the waist, and stays out of your way during hard efforts. At a fraction of the price of larger buoys, it’s a solid first open water accessory for new swimmers or those who don’t need the storage capacity.
Best Premium: DORSLL POD High-Visibility Swim Buoy
The DORSLL POD is a premium open water safety buoy designed for maximum visibility. Its bright high-visibility design makes it easy to spot in all conditions, and the durable construction handles regular open water training well. The secure clip system keeps it in place at pace, and its waterproof interior can hold essentials for longer training swims.
Buying Tips
- Always check whether your open water swim venue requires a tow float — many UK lakes now mandate them for solo swimmers.
- For triathlon racing, check the race rules — some events permit tow floats and some don’t. Buy based on your training needs first.
- Pair your tow float with a bright silicone swim cap (rather than the latex one supplied at most events) for better visibility in open water.
Care and Maintenance
Rinse your tow float with fresh water after every open water swim, especially after salt water or lake sessions. Allow it to air-dry fully before storing. Avoid leaving inflated floats in direct sunlight for extended periods as UV exposure can degrade the material over time. Check the inflation valve seal regularly — a slow leak in open water is a safety risk.
