Abstract
Abstract An improved vibration damping handle grip having a vibration damping elastomer and a webbed, tack-free elastomer-coated tubular shaped material. The vibration damping handle grip is fabricated having a vibration damping elastomer nearest a vibration generating handle, and a webbed tack-free elastomer-coated tubular shaped material adapted to conform to the vibration damping elastomer-covered handle shape, thus providing a comfortable, substantially slip free hand gripping surface.
