In Hot Yoga (or Bikram Yoga), the room is often heated to up to 40 degrees, causing participants to sweat quite a bit. In this case, it is important that the yoga mat absorbs moisture. Depending on personal preference, it can be used with or without an additional yoga mat and is reversible. The mat is washable and can be compactly rolled up for transport. Naturally, most yogis value environmental friendliness. The Adidas Hot Yoga mat is made of 43% eco-friendly and biodegradable natural resin.
