Want a comfortable grip but prefer the look and feel of your wood or other traditional hand grip? Sims Vibration Laboratory has designed another Product That Works. The new LimbSaver® Insulator Strip attaches on the front of the grip directly to the riser, insulating your hand from the cold. The new LimbSaver® Insulator Strip does not increase your grip width, but allows you to carry your bow more comfortably. Built from our proprietary NAVCOM" (Noise and Vibration Control Material).
