The SP yoga mat was designed with one goal in mind; to create a beautiful eco-friendly yoga mat which eliminates the need to bring both a towel and mat to class. The SP mat is infused with a unique luxurious & absorbent microfiber layer which is as absorbent as a towel on top, so the more you sweat the better the grip. made from 100% natural tree rubber, they're also extremely eco-friendly, biodegradable, recyclable and only made with water based inks. The mat has zero odour and No toxic smell. We include a free carry strap with every yoga mat.
