Abstract

A golf club head with low peripheral and rearward weighting includes C-shaped and annular weights connected with at least one of the rear and bottom surfaces, respectively, of the head. The weighting within the peripheral weights is adjustable between the heel, rear, and toe portions of the head to customize the weight distribution of the head in accordance with a golfer's swing. The added weight and its orientation increases the moment of inertia of the head and reduces the rotation thereof.
