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 resistant, air-permeable and do not come off in the shower, pool, or sauna. They can be stretched lengthways by approximately 130 -140%. 3BTAPE is used in kinesiology taping treatments of muscle fascia and performance enhancement. Kinesiology taping and Acu taping techniques can be used for many different applications.
