Gore's Alp-X 2.0 Jersey is made with a moisture-transferring, breathable fabric and mesh underarms for serious comfort on every ride. The mesh back panel sits right where your pack is, and combats the dreaded sweaty back. It also has an ergonomic cut for a great fit and feel, a full zipper for easy on/off and reflective accents for safety. This technical piece also has a ton of pockets to carry everything from a map to food to a jacket. Plus, there are silicone prints on the shoulders for durability and to keep a pack from slipping.
