Light like a jersey, yet protective like a jacket, Castelli's Gabba 2 Long Sleeve Jacket is the do-everything top for all seasons. It's made from Windstopper X-Lite Plus fabric for lightweight wind protection, and it's got a water-repellent finish for those misty morning rides. Nano Flex fabric inserts under the arms keep this jacket comfortable as you move, and Storm-flap construction in the back keeps wheel spray at bay. Plenty of additional venting comes courtesy of the full-length front zipper with wind flap. The three rear pockets give you plenty of space to stow your essentials, while effectively draining moisture to keep you and your things dry.
