The Topcooper Dry Bag Swimming Tow Float is designed to increase the visibility of open water swimmers. The Hi Vis colour scheme makes this buoy visible from a long distance.The float has an adjustable waist strap and is easy to inflate and deflate via the wide mouth inflation valve. It attaches around your waist via the adjustable webbing strap, which can be set to the desired length for swimming.This tow float has air chamber to keep the bag afloat in case of accidental puncture. Inside there is a dry chamber, which closes like a regular roll top dry bag and has enough space to store your essential items while you swim. This float is constructed using high quality materials and RF-welded seams for strength and durability, however, we recommend 'double bagging' electronic items before placing them inside.Ideal for triathlon training and open water swim training.
