HawkHydro+ is a water-based emollient designed specifically for use with IASTM tools. With all of the benefits of the traditional oil-based emollients and none of the mess, HawkHydro+ is easy to use and wipe away. After use for IASTM treatment, the polymers in HawkHydro+ dry to a gentle adhesive to prepare skin for kinesiology taping. Packaged in a squeezable bottle to avoid cross-contamination. Single 4 oz. bottle.
