Many mats are made of harmful chemicals – NO THANKS, but thinksport’s yoga mats are not – YES PLEASE! I personally don’t like to think of myself rubbing, laying, or sweating against a mat that is seeping chemicals into my skin. Now, I don’t have to worry about unnecessary chemicals while I am trying to relax and make my body healthier while doing yoga or pilates. This mat is thicker than any of my previous yoga mats, and I won’t be going back to those flimsy, chemical smelling mats. The mats are even biodegradable WOW. Thinksport really went above and beyond in designing this mat for yoga and Pilate enthusiasts.
