The guard is held firmly in place with especially designed cover with two front panels made of Hi Tech, two way stretch Polycotton/Lycra which is up to 30% cooler than the original cover.

This fabric allows movement of moisture, to speed evaporation, which is the body's natural cooling method. (If a bra is worn under the Guard, we recommend it be of a synthetic fabric type for the same reason.)

The Guard cover has plenty of stretch so the cover is fitted first, then the guard is inserted between the front layers of fabric, and removed after competition or training, to further aid cooling.
