The P2 React Putter Grip is an oversized grip with slightly rounded sides and a flat section on top for both thumbs to sit comfortably, but is smaller than the P2 Reflex. It features a minimal taper from top to bottom to reduce tension throughout the hands and arms. The React features P2s patented design where the shaft is housed through the bottom of the grip to allow for a much higher topside which brings the scientifically proven benefits into play. Weight: 148 grams. The patented P2 technology is based on the way the shaft is housed through the bottom of the grip, unlike traditional grips where the shaft is installed though the center of the grip. This effectively elevates the golfers hands at address, locks the wrists in place and creates sought after shaft-forearm symmetry.
