The ZOIC Carbon Liner is the right choice if you want firm support without adding bulk. Designed for epic endurance mountain bike rides of 4+ hours, the Carbon Liner delivers optimal performance all day in the saddle. The Italian-made chamois is scientifically engineered with three densities of foam that concentrate support to relieve key pressure points in a contoured shape that minimizes bulk. A breathable base layer and multi-level design accelerate moisture transfer away from the skin.
