The Castelli Prologo 7 SS Road Jersey is made for those JRA rides. Just Riding Along. You're not aiming for new Strava records or to win the city-limit sprints, but you do want a jersey thats comfortable and looks great.The jersey has a neutral cut — not racy but also not flapping in the wind. But the high-stretch micro-piqué fabric means it fits more shapes than a Castelli race jersey. Adding to the fit and comfort are the four-way-stretch sleeves that seem to disappear, since you dont really feel them at all, right down to the raw-cut sleeve ending that never constricts.This jersey offers full sun protection: the main body is rated at UPF 50 while the sleeves are UPF 30, which means they still block 97% of damaging UV rays.Important Castelli features like the drop-pocket design, easy-sliding full-length YKK® Vislon® zipper, and reflective details on the back will keep this jersey in the short rotation in your wardrobe.WHAT IT ISThe perfect all-around jersey for everything but racing. Comfortable stretch fit, excellent moisture management, four-way-stretch sleeves with raw-cut edges, and full sun protection are just some of the features.Castelli Prologo 7 SS Road Jersey FeaturesMicro-piqué polyester knit on the body for great moisture management with a soft handVelocity Rev2 fabric on sleeves with raw-cut sleeve endingsFull-length YKK® Vislon® zipper with neck protector3 rear pockets with drop-pocket design for optimal pocket placementSilicone gripper elastic at waistReflective details on both sides of pocket16-38°C / 61-100°FWeight:130 g
