The LimbSaver Vibration Insulator Strip attaches on the front of your bow's grip directly to riser, insulating your hand from cold. It's made from LimbSaver's proprietary NAVCOM technology (Noise and Vibration Control Material), which effectively absorbs a wide range of frequencies to dissipate energy and vibration. It measures 3-1/2 x 0.5 inches (LxW); note that it won't increase your grip width. Using state-of-the-art technologies, LimbSaver produces highly effective noise- and vibration-dampening products for archery and firearm products, including bow stabilizers, recoil pads, rifle slings, and more. Proudly engineered and hand-made in the USA, LimbSaver products are widely used by outdoor enthusiasts, military, law enforcement, and more.
