It's all about touch.We call it Hands to Hearts. Our mats are hand-woven and a card with the weaver’s signature is attached to the mat. We believe handweaving lends a unique quality to our mats that can’t be replicated by the machinemade variety. It’s intrinsic, it’s inherent. There's a different feel and energy experience on a product made by hand. Cotton will last longer than synthetic PVC substitutes (PER,TPE) or rubber. They can be used indoors and outdoors. They work well for most types of yoga.
