This lightweight travel yoga mat is a generous 5mm thick and as a result is a cushioned, comfortable mat on which to practice. It is a great sturdy surface, providing a warm connection to the earth beneath you. At the same time - at only 670 grams it is so light you can carry it with ease - where ever your practice may take you! This mat is made of TPE under high temperatures which creates a closed cell finish to the material which makes it anti-microbial and easy to clean. It is non-PVC and not toxic to the environment.
