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%.
