What Our Gearhead® Experts Are Saying:"I grab the Prologo Lite 2 for everything from long tempo days to recovery spins. It breathes incredibly well, the sleeves stay exactly where I want them, and the zippered pocket is a nice bonus for keys or cards. It’s the kind of jersey you forget you're wearing—in the best way."From early-season endurance rides to midsummer hill repeats, the Castelli Prologo Lite 2 Jersey is built for those of us who want breathable comfort without sacrificing performance details. It's a jersey that excels on hot days and long routes, keeping us cool, covered, and dialed-in thanks to its clean, fuss-free design. Castelli uses 100% polyester made from 66% recycled yarns for maximum airflow and moisture control. Raw-cut sleeves with welded seams stay in place without pinching, and a full-length YKK® Vislon® zipper makes for easy on-the-fly venting. With three traditional rear pockets plus a zippered one for valuables, the Prologo Lite 2 has the everyday functionality we need—finished with a silicone gripper at the waist to keep everything secure through every effort.
