Our Neutralizer Grips are scientifically tested to distribute pressure more evenly across the hand while also offering a significant ledge for your fingers to perch onto. This combined with our super-tacky grip material results in maximum control & comfort. Medically designed to conform to the hands anatomy. This relieves pressure-related symptoms such as pain & numbness which often lead to fatigue. Flat ledge under the grip provides enhanced grip. Super tacky yet durable grip provides superior control.
