3B Kinesiology Tapes are made from cotton rayon fiber and are latex-free and hypoallergenic. 3B Tapes are for kinesiology taping, acu taping and sports taping. 3B Kinesiology Tapes have a skin-friendly, thermoplastic wave-like acrylic adhesive on one side. The wave like adhesive is used to push sweat and moisture away from the kinesiology tape. This means that 3B Tapes are water resistance, air-permeable and do not come off in the shower, pool, or sauna. They can be stretched lengthways by approximately 130 to 140 percent. 3B Tapes are used in kinesiology taping treatments of muscle fascia, tendonitis symptoms and performance enhancement by the natural process of improving circulation and lymphatic drainage.
