Measuring 4X the length of other cold packs, this is the reusable cold wrap that covers the entire back. Chilled in a home freezer for 30 minutes, the oversized wrap is filled with a proprietary gel that becomes as cold as ice yet remains pliable, dry, and mess-free. Helping to heal sore muscles and tame spasms with soothing cryotherapy, it comfortably molds to the body’s contours and can be draped around the shoulders or wrapped around the quadriceps or knees for a targeted 45 minutes of cryotherapy that helps numb pain and reduce inflammation after an injury or speed recovery from a workout. The large wrap is encased in durable nylon that wipes clean after use, with bonded seams to prevent leakage. 21 1/2" L x 13" W x 1/2" D. (4 3/4 lbs.)
