BLOCKER WB UNDER GLOVES The BLOCKER under gloves are designed to supplement other REV’IT! gloves and make them more suitable for cool conditions. The inner material wicks moisture from the hand to maintain a comfortable temperature, and the upper of the BLOCKER is made of REV’IT! WindBarrier®, which helps keep your hands warm and dry. Stitching on the outside of the glove increases the comfort, giving you a completely smooth feel against your fingers.
