From the collar, to the sleeves, to the waist, the warm stretchy fabric in the Castelli AR Jersey FZ protects your skin against the cooler temperatures of the fall season. The construction is light enough so you do not overheat when the temperatures rise into the upper 60s F, yet the fabric is warm enough to take that bite out of cool weather. The perfect fit in this long-sleeve cycling jersey is combined with fabric that circulates air so you stay dry and your skin continues to breathe. Performance has been designed in not only the combination of fabrics but also in the way the cycling jersey is constructed. When you ride in the AR Jersey, you feel a very smooth jersey drape over your skin so you are not only extremely aerodynamic, but you will never having material snagging your upper body as you are tackling a fast flat ride against the wind or climbing a steep mountain. Complete comfort for the cyclist who wants to focus on making those hard efforts is ensured by Castelli designers. Full-length Vislon zipper, 3 rear pockets and reflective tabs to keep you visible to motorists on those early morning or overcast days top off the qualities to make the Catelli AR Jersey FZ ideal for the serious cyclist.
