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%.
