The Zone3 Swim Safety Buoy / Dry Bag Donut is a tow float and dry bag for your valuables combined. The donut shaped buoy features a double lined central dry bag which means you can assess a drink, nutrition, spare goggles, Go Pro etc whilst on the move. The adjustable dual belt design attaches securely around the swimmer's waist and the leash ensures that the product remains out of stroke-range whilst swimming.

Use as a normal tow float when you don't have valuables to pack. When the buoy is lying flat it measures 45cm x 34cm.
