The SCOTT Mellow Grip is a dual density motocross grip with a soft, Vario Blok design outer density, surrounding a long-lasting, firm density core. The outer Vario Blok design offers superb, consistent grip and helps reduce arm and hand fatigue through superior vibration absorption. It also makes it one of the most comfortable motocross grips out there! The included grip donuts further increase comfort and greatly reduce the chances of getting thumb blisters.
