The UnderWARE glove liners are worn inside your normal off-road/MX gloves and snugly adhere to the rider's hands. The UnderWARE liners take the beating your palms and lower fingers usually endure from the inside of your riding gloves. The Kevlar fibers of the UnderWARE liners absorb the friction between glove and hand that would otherwise cause blisters. The liners take the chaffing and rubbing that hands normally endure while you ride through the gnarliest of whoops or crank down a wooded trail. The end result in no more blisters! The Dupont Kevlar material is machine washable right along with all the rest of your riding gear for easy maintenance.
