Hand grip sleeve for golf putter

Abstract

A hand grip sleeve for wrapping about a grip of a golf putter includes a flexible sleeve defining a sleeve hole extending from the front end to the rear end and a longitudinal opening cut through the peripheral wall, and a fastener provided at the flexible sleeve at two opposite sides of the longitudinal opening and operable to open or close the longitudinal opening. The fastener may be a hook and loop fastener, a zipper or snaps. Thus, the hand grip sleeve can be directly and conveniently attached to the grip of a golf putter to increase the diameter of the grip area of the golf putter for gripping tightly and comfortably. By means of the design of the longitudinal opening and the fastener, a user can easily install the hand grip sleeve on the grip of a golf putter.
