Hunters Element Core TopThe CORE base layer is designed to regulate your body temperature at the base level through all weather conditions. The compression weave is designed to cling tight to the body to help with muscle fatigue and rapid wicking. The body mapped design has been athletically shaped, so the high wicking fabric can sit tight to the body in order to absorb and disperse as much sweat as possible, all the while allowing maximum movement in the high stretch areas.
