Saving approximately 12 watts at 40 km/h compared to a normal race-fit jersey Castelli's Free AR 4.1 Jersey is all about speed. However, Castelli doesn't cut corners when it comes to comfort either, the high-tech fabrics being excellent in hot wea

What began as a World Tour pro-level jersey has, over time, evolved into what it is today -  a high performance but impressively functional jersey for any rider and for all-around use. Not only do the fabrics used help reduce drag they work hard to remove sweat, meaning you remain dry and comfy even when working up a sweat.  And you'll find the full-length zipper adds extra ventilation options when the intensity cranks up. 

Practical features that make it such a great do-it-all jersey include the three rear pockets for day-long storage plus you'll find an extra zippered pocket for valuables. To the waist, a silicone gripper keeps the jersey flush to the body, while the mesh raw-edge arm grippers hold firmly without irritation. Add to that reflective strips that increase visibility as the light fades and you can be riding from dawn till dusk.

Thanks to its aero cut and high stretch fabrics the Free AR 4.1 Jersey is a fantastic choice for racing. However, we think it is also perfect for long training summer rides, speedy sportives or simpy to look awesome riding your favourite roads this summer.
