Yoga’s great for the soul and all, but when it comes to yoga mat design, it seems like all the soul is sucked out. At least we think that’s what Terra Breese, the creative who launched Devi Mats in 2006, thought. To solve the monotone problem, her line of yoga mats — each 1/4″ thick and printed so that they retain their grip — have organic designs like plants, the Aurora Borealis, and fire. Because nothing is more relaxing than envisioning yourself about to be engulfed by an erupting volcano.
