Please refer to the instruction sheet included with your mat. The microfiber is intended for a hot and sweaty practice. If you find your find slippery at first use, we advise a quick spritz with water. If you prefer a drier practice, flip your mat. Our mats are reversible. This makes them uniquely perfect for all types of practice. We're running out of ways to let customers know that our mats are reversible but we've managed to find another way, we're now even putting this key feature in the product title :-)
