Our Gaia Eco Friendly Yoga Mats are made from a newly developed environmentally friendly closed-cell Nitrile/Buna N Rubber (NBR) foam, and are free from any toxic materials.  Their low apparent density reduces weight without performance loss.  This foam does not contribute to greenhouse emissions.  Resistant to most chemicals and petroleum products, our mats won't break down when they become wet.  The super soft high resilient foam offers great support and gives cushion for kneeling, poses and jump-backs, while providing a fantastic comfortble feel, slip resistance, and resistnace to cold and heat.  The mats are easy to clean and have great shock absorption.  Can be used for Bellydance warming up, Yoga, Pilates, exercise aerobics, redhibilitation and hydrotherpy.  The mat is blue with Black Bellydance print, has rounded corners and is soft and flexible.
