Our 100% Cotton Yoga Diamond Pattern Rugs are an eco-conscious yoga mat because they are made of a natural material, biodegradable and PVC-free. Cotton yoga rugs have been used for centuries for Hatha Yoga and are considered to be the first mats ever used for Yoga practice in Mysore, India. These yoga mat rugs are excellent for hot yoga because the tightly woven, thick weave cotton fibers soak that up moisture and help you maintain your poses without slipping. When laying your cotton rug on a wood floor, we recommend lightly misting the entire rug surface to reduce slipping. This classic cotton diamond pattern rug can also be used on top of your favorite yoga mat for extra padding. Wash your yoga rug in cold water and hang it to dry. Please do NOT put it in the dryer, as the heat of the dryer will cause the rug to shrink. Your rug may tighten up after air-drying but it won't shrink. Your cotton yoga diamond pattern rug will maintain its beauty and soften with repeated use.
