ROCKTAPE has been designed and developed in California to create a Kinesiology tape which is stronger, more adhesive and stretchier than traditional Kinesio Tape. It has been manufactured with a tighter weave with the aim of increasing the support provided to the muscles and joints. It is also a bit more elastic than other kinesiology tapes on the market with 180% stretch, a similar elasticity as skin which helps to promote full range of motion. Rocktape is manufactured with a mixture of 97% organic cotton and 3% nylon .
