Designed for visibility and added buoyancy while you swim-and doubles as a dry bag for water sports adventures. Whether you&';re taking a lap around the lake, training for your next triathlon, or heading out for an open-water ocean swim, this inflatable swim buoy adds an extra layer of safety with visibility and buoyancy right there when you need it. Getting started is simple: fasten the belt around your hips, inflate the air chamber using the mouth valve, and let the buoy trail behind you as you swim. It creates almost no resistance in the water, so you can stay focused on your pace. There&';s also a separate storage compartment for essentials like an energy bar or your keys-kept apart from the air chamber-so your must-haves stay with you every stroke of the way.
