Sorbothane¨, a one-of-a kind visco elastic polymer, has been medically and scientifically proven to be the finest cushioning material available today . Kick-Eez pads reduce more recoil and do it better than any other pad. Less recoil reduces flinching, eases sore shoulders or cheeks. By reducing the rebound effect of the first shot, second shots are quicker and more accurate. Pad will not "bottom out" as other materials tend to do even after thousands of compressions. Originally designed for use on extra large bore guns, but is suitable for any gun to tame heavy recoil. It has a basically flat back and is canted downward on both ends for easy shouldering.
