The ICE20 Single Knee Compression Wrap uses real ice instead of gel packs, allowing it to stay colder longer to more effectively reach deep tissue pain and soreness. It is made of a high quality neoprene (latex free) and has adjustable Velcro straps that allow it to stay in place for comfortable, form-fitting therapy. It includes a refillable, removable no-leak 11" ice bag with an easy open cap and a durable mesh carry bag.
