The Wilson Feather Thin Badminton overgrips are designed to ensure great feel in return for minimal racket weight gain. The 12 black overgrips are ultra-thin & ultra-light which improves finger power & wrist play & enables a loose grip to be maintained on the handle. This relaxes the forearm muscles & increases flexibility, wrist speed, the range of wrist rotation & feedback from the racquet, improving shot control & enabling faster grip changes.
