The Flo-Babe PU Yoga Mat has an innovative moisture-absorbing design, designed to increase the grip with increased moisture. The mat features double-sided technology, the top side of the mat, the “sticky” side, is made of an Eco-polyurethane (PU) material which absorbs moisture (hence the grip). The bottom side is made from natural rubber which provides more cushion and unparalleled grip on the floor.
