The external part of floats is made of nylon textile with a PVC coating. The internal part is made of micro neoprene with an antiskid layer (this prevents the float from rotating around the leg during work). The carrying element is polyethylene foam. The fastening band is elastic and gives a more comfortable feeling for fastening the float around your leg. Watsu floats are not life rescue equipment, but are used for Watsu aqua therapies.
This new size expands the possibilities of working with the body in the water. The XS float has half the buoyancy of the red S float and, thanks to its greater length (the length is the same as the yellow M float), it can also be used on the thighs.
