With Castelli's Gabba 2 short-sleeve jersey, you'll get a high performance piece of gear that improves upon one of Castelli's already impressive designs. It's built to be fully aero, fully breathable and to provide you complete protection from the elements as you ride. Windstopper X-Lite fabric with water-repellant finish moves with your body and doesn't restrict your movement. It provides you 100% protection from wind with up to ten times greater breathability than other windproof fabrics. Updated to include a draft flap behind the zipper to seal in warmth, better drainage in the pockets and redesigned to have a slightly more refined fit, this is the race jersey that you'll depend on.
