Our Cotton 8 Foot Yoga Strap is made from natural 100% cotton. Imitators use nylon which causes frequent rug burn, rashes, and is hard on the skin. Our cotton straps are woven tightly to form a textured yet soft non slip surface. The cinch buckle is lightweight and extremely durable under pressure. It's easy to adjust and the perfect width that makes it easy to hold without cutting off circulation. Yoga straps are essential for perfecting alignment and increasing flexibility, and 8 feet is more than enough length for most people.
