NATURAL AND SUSTAINABLE - Gurus best-selling Roots Natural Yoga Mat is 5 mm thick and is made from sturdy and supportive layer of sustainably sourced rubber. It is topped with a thin and flexible layer of natural cork. The cork material keeps your mat odor-free without using cleaners. NON-SLIP AND WATERPROOF - Cork naturally displaces moisture and get grippier when wet, so you don’t have the same slipping issue you have with other mats. Cork yoga mats are grippier and have a better non-slip effect when wet. Even during your sweatiest practices, this mat works perfectly without a towel. IMPROVES YOGA PRACTICE - Our 72x25 inches yoga mat gives you the option to use either the cork or rubber side depending on your practice, location, or mood. Both sides offer traction that helps improve your yoga practice. Men, women, and yogis alike love taking advantage of both non-slip surfaces. GREAT FOR INDOORS & OUTDOORS - The cork layer of the Roots Yoga Mat does not absorb heat the way rubber and foam mats do, making this mat ideal for outdoor practice. The natural rubber backing grips almost any surface so you can practice even outside the studio. GURUS GIVES BACK - We have teamed up with Trees For The Future, a non-profit that plants trees with rural communities in the developing world, to plant a tree for every Gurus product purchased. This ensures that every product made gives back to the natural resources that helped create it.
