A yoga strap extends your reach in stretching and mobility exercises, allowing you to hold positions that would otherwise require more flexibility than you currently have. The Manduka Align strap is made from unbleached natural cotton with a zinc alloy interlocking buckle that holds securely without slipping during sustained holds. At 10 feet long and 1.75 inches wide, it provides enough length for most lower extremity and shoulder stretches. For climbers, it is useful for hamstring and hip flexor stretching, shoulder and thoracic mobility work, and assisted flexibility exercises during rehabilitation.
