Castelli Free AR 4.1 Full Zip Jersey

Season : Spring Summer 18

Brand : Castelli

Code : CS18003RED

Weight : 0.2KG


Complementing an aero setup, the Castelli Free AR 4.1 Full Zip Short Sleeve Jersey has a design and fit to reduce drag; saving you up to 12 watts compared to a normal race fit jersey, when riding at 40km/hr. Weighing just 123 grams in a size large, this lightweight offering features Velocity dimpled fabric on the front and shoulders so moisture is wicked from the body and will dry fast, leaving you fresh and cool.

At the armholes, Nervato fabric improves aerodynamics and the sleeves are held smoothly and securely against the arms thanks to mesh raw-edge arm grippers. Although this is an aero fit jersey, there is still plenty of stretch to ensure you have full freedom of movement with no restrictions when in the riding position.

Silicone gripper elastic ensures this jersey will stay in place without riding up and three rear pockets and a zipper pocket provide storage for essentials and more valuable items. When you're working hard and start to get too hot, you can add some extra ventilation via the full-length YKK zipper, and the offset collar is supremely comfortable against the skin. Reflective strips enhance your visibility for added safety on the roads.

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
