Leather Yoga Sling with Optional Yoloha Cork Yoga MatA yoga sling that is as flexible and strong as your poses. Gravity and friction are harnessed in the design to hold your mat rolled and ready. A single piece of thick bison leather wraps around the mat and through itself, synching tight and clipping to a leather shoulder strap. Cork yoga mat is available through our friends at Yoloha Yoga, purveyors of fine cork yoga mats.
