An overgrip for a golf club is provided that includes a shell defining an interior and an open end, with a soft material disposed within the interior of the shell and capable of conforming to the shape of a club inserted into the interior through the at least one open end to engage the club. The shell can be formed with a pair of halves joined by a hinge to assist in the positioning of the club within the overgrip and can additionally include a locking mechanism to selectively hold the shell in engagement with the club positioned therein.
