Kinesiology tape is a thin, light and stretchy blend of cotton and nylon. It's designed to mimic the skin's elasticity so that you can use your full range of motion. The tape's medical-grade adhesive is also water-resistant and strong enough to stay on for 3 to 5 days. Kinesiology tape has been used by world-class and professional athletes in their sports. It allows them to perform even with minor pain, soreness and injuries.
