Underwrap or Pre-Wrap is a lightweight foam wrap designed to protect the skin from tape adhesives during taping techniques using sports tapes. This light veil like foam film tape, is used to protect the skin from the glue used in zinc oxide style tapes. It is simply wrapped around the area to be taped and the tape applied over it.
