HIGHLY VISIBLE - In open water, swimmers in black wetsuits are practically invisible. This colorful floating buoy is particularly notable for boaters, jet skis and paddlers. If you are beheaded by a jet ski or a speedboat, the orange floating buoy can also be an effective means of preventing a shark attack. GOOD HELP FOR SWIMMERS - For swim coaches attached to the waist by a tether belt, you can leave it behind when you don't need it. In the event that you tense up or just need rest, you can grab the float. EASY CARRY & STURDY AND DURABLE - Use environmentally friendly PVC material, not easy to cut, sturdy and durable. When you're ready to use it, just blow the air through the new blower nozzle, quickly release the air and roll it up in a small bag when you're done using it. STORAGE OF PERSONAL ITEMS - This new floating buoy has a waterproof storage compartment that is separate from the inflatable air chamber. You can put your things in your pocket, e.g. B. Cell phone, sunglasses, sunscreen, clothes and socks and so on. The triathlon training buoys series will make you a safer swimmer by combining utility and visibility. This buoy is essentially a lifeguard that allows you to track or record your swimming behavior with a trainer, lifeguard or swimming partner.
