4ft Yoga Belt is made of 100% natural cotton, woven tightly with an adjustable buckle at one end and is durable. The smooth texture of the belt prevents injury to hands and feet, which may be caused by the rubbing of the belt against the skin during yoga practice. The Yoga Belt allows you to expand your range while achieving more challenging positions and sustaining poses for longer periods of time, hence deepening your stretches and extending your reach. The easy-release cinch buckle holds the belt securely in place.
