Extra Large Cork Yoga If you are looking for a natural, eco-friendly all-around mat that can handle a vigorous Vinyasa class but still comfortable enough for a Yin practice, this Cork mat is for you. Its surface is made from the bark of a tree and provides an antibacterial surface for your yoga practice. Due to cork's amazing qualities, the grip increases when you sweat which makes it also perfect for Hot Yoga. This mat feels great under your hands and feet and gives you a soft, but supportive, earthy feeling. Perfect for taller yogis, broad, tight shoulders and for anyone that appreciates a little more space on and off the mat. TIP: Splash some water on the mat for a better grip right before use!
