Rugged grip panels made from tough G10 fiberglass offer the durability and superior gripping texture of modern composite materials. Advanced G10 laminate won't absorb moisture, resists impact, and won't expand or contract due to temperature fluctuation-perfect for all-weather operations and extreme conditions. Texturing is CNC machined into the laminate, then hand-finished to ensure uniform pattern depth. The hard surface allows the texturing to be cut a little sharper to give more "bite" than traditional checkered wood grips.
