This sleeve is specifically designed to fit our gel packs and allows our patients to easily place (and replace) gel packs without having to remove the wrap. Cool Jaw’s patented design thereby allows patients to always maintain constant compression over the surgical area, which helps to reduce swelling. Features a builtin chin cup to help reduce slippage and maintain proper positioning of the jaw wrap. Two rows of Velcro® closure at the top of the head provides a universal, adjustable fit. Jaw wraps arrive with your choice of two or four gel packs, so that patients can rotate packs between usage.
