## Abstract

An improved handle grip cover formed of a knitted, braided, or woven tubular shaped material impregnated with a synthetic or natural elastomer. The grip cover is fabricated by placing a tubular shaped material, preferably elastic, over a form with a non-stick surface, and impregnating the tubular shaped material with a synthetic or natural elastomer. The tubular material is then cured, and peeled off of the form and trimmed to the desired length. The grip cover may be applied to a handle of a manual tool, a power tool, a piece of athletic equipment, or other article generally gripped by the hand.
