Developed by a physical therapist, these wraps retain heat or cold and inflate to provide personalized compression therapy. The wraps have flexible high-glycerin gel inserts that can be warmed in a microwave to soothe sore muscles or joints, or chilled in a freezer to reduce painful swelling. A removable hand pump inflates air chambers inside the wraps, providing circumferential compression and personalized support that can mitigate inflammation and promote faster recovery. The wraps can be worn under clothing and conform to the body without inhibiting movement, Velcro fasteners ensure they remain in place, and they remain hot or cold for up to 40 minutes. Specify Ankle or Wrist Wrap.
