Circuit Tape is a cohesive tape specifically designed for skin protection. Cohesive indicates that the tape does not contain an adhesive, rather it sticks only to itself. This makes Circuit Tape ideal for use in situations where chalk or perspiration could compromise the bond of an adhesive tape.
For training scenarios or projecting on sharp holds, Circuit Tape can act as a preventative measure for skin preservation, and won't leave your skin soft and vulnerable like many adhesive tapes will.
