    • Castelli Aero Race 4.1 Solid Jersey SS18

  • Castelli Aero Race 4.1 Solid Jersey

    Look great and save energy better than ever before thanks to this Aero Race 4.1 Solid Jersey from Castelli. Its energy-saving rates really are something to behold: an extra 12 watts when riding at 40 km/h compared to a normal race jersey. The drag-reducing material is dimpled too, which means it wicks moisture away from your skin and is quick to dry, so sweat never needs to get in your way again.

    Great levels of storage for those longer rides is provided by a secure zippered pocket on the back for that extra practicality. It’s a great fit—close to the body without restricting movement—with a silicone gripper at the waist, and breathable raw-edge elastic in the arms to keep it in place. It’s all rounded out by reflective strips in all the right places to help keep you safe and seen in low light rides.

    Designed to give you an (un)fair advantage in races, the Castelli Free AR 4.1 Jersey is great for anyone looking for a comfortable summer ride as well.
