The YOGAaccessories™ Pure Jute Yoga Mat is made from jute -- a natural plant fiber grown primarily in South East Asia. Jute is a highly versatile fiber, combining breathability with high tensile strength. This mat is created by combining jute fibers with PER, a phthalate and heavy metal free rubber-like substance that gives the mat the same great performance and ''stickiness'' of our conventional yoga mats. The result is a mat that looks distinctive, is highly functional, and yet has an eco-friendly footprint. With this mat, you will not be compromising on the sticky, cushioned texture you count on for your most strenuous yoga routines. These mats are 4mm in thickness which provides extra cushioning, and are 72'' long by 24'' wide.
