3B Scientific green kinesiology tape is used for treating muscle fascia and tendonitis symptoms, and provides performance enhancement by improving circulation and lymphatic drainage. The tape is made of latex-free, hypoallergenic cotton-rayon fiber for comfortable wear, and has a thermoplastic, wave-like acrylic adhesive that pushes sweat and moisture away. The tape is water resistant and air-permeable for staying on in the shower, pool, or sauna, and stretches lengthways by approximately 130 to 140 percent for firm wrapping. The tape measures 16' x 2" (L x W). (L is length, the horizontal distance from left to right; W is width, the horizontal distance from front to back.)
