Castelli Sottile Due Jacket

Castelli’s waterproof Sottile Due Jacket is lightweight, wind resistant, breathable, and conveniently packs into a back pocket whenever there’s a chance you’ll need extra warmth or rain protection. Its sleek, race-cut design keeps you aerodynamically fast, while mesh underarms allow ventilation to keep you at the right temperature. There's even a zipper opening at the back for accessing your jersey pockets without having to take it off or roll the jacket up.
