The Harmony™ Fusion Yoga Mat by Jade combines the best of both worlds: eco friendly materials with professional-grade performance design. At 5/16'''' thick (thicker than our deluxe 1/4''''), this mat will cushion and protect your joints, while providing a non-stick, durable, and stable open cell surface. Perfect for Bikram or hot yoga, Jade's Fushion Mat is eco conscious: containing no PVC, synthetic rubber or plastics, and is phthalate-free. Plus, through the charity Trees for the Future, Jade plants one tree for every yoga mat sold!
