Product Description Made with natural rubber, the Jade Fusion is Jade’s thickest, most comfortable mat. At 5/16- inch thick, the Fusion mat is great for your yoga/Pilates/core fitness practice. 68 inches is the standard length. Amazon.com Jade mats are made by combining natural rubber from the Far East with Western technology to form a mat that is perfect for your yoga practice. The Jade Fusion mat is extra thick at 5/16-inches for extra cushion, and is great for yoga, Pilates and core fitness practices. As Jade mats are made with open cell, natural rubber, you can say goodbye to slipping on your practice mat–even if it gets wet with perspiration. Natural rubber’s superior slip resistance properties ensure a solid grip every time, and additionally provide resilience, compression set resistance and cushioning, resulting in a solid blend of comfort and performance. The natural rubber used to create Jade mats is a renewable resource containing no PVC or ozone depleting substances, and the mats are made in the U.S.A. in compliance with all U.S. environmental and labor laws. Jade believes in being good to your body and good to the Earth, and–through a partnership with Trees for the Future–when you buy a mat, Jade plants a tree.
