The classic inflatable tow float includes a leash and waist strap which is adjustable. This float is perfect to make the swimmer more visible to other water users and from shore. If you need a rest you can hold onto the float and it will easily support an adult's weight. Use the back of the valve cap to deflate.
Please note, this is not a buoyancy aid, it does not give any buoyancy whilst swimming. The tow-float floats behind the swimmer on a short leash.
