Castelli AR 4.1 Jersey - Black

ONE FOR ALL

This jersey is an evolution of our pro racing jersey from just four years ago. It’s also our first aero race jersey that didn’t get retired when the next generation of faster, more aero jerseys came along. The Aero Race 4.0 Jersey was very fast but also an amazing mix of classic good looks and a stretchy fit that works on a lot of body types, not just the skinny racer. For the 4.1 version we’ve taken it a different direction, away from pro racing, by giving it the convenience features that seamed superfluous when we designed the 4.0 to win the Giro d’Italia. This updated jersey gets a zippered rear pocket, a flap behind the zipper to protect your neck, updated Velocity dimpled fabric on the front and an angled pocket for easier access. This makes it the one ideal jersey for all your rides, whether you’re sprinting for the win or trying to survive the Sunday group ride.

Features:

• Saves approximately 12 watts at 40 km/h compared to a normal race-fit jersey

• Nervato fabric at armholes for improved aerodynamics
• Silicone gripper elastic at waist
• Mesh raw-edge arm grippers
• Zippered rear pocket
