This Wrist and Hand Heat or Ice Wrap is made of a tough, flexible gel covered with a four-way stretch material, which allows maximum conformity, heat transfer, and comfort.

The cold wrap will usually numb the treated area within 5 minutes without the severe shock and pain experienced with ice or ice water treatments. The wraps will remain cold for 20 to 40 minutes. Hot: Moist heat quickly penetrates muscles and joints when a warm wrap is applied. The wrap will continue to provide moist heat for 20 to 30 minutes before it will need to be reheated.
