Castelli Corretto LS Jersey Summer weight. Race fit. Ready when the pace turns serious. The Corretto LS uses a two-fabric strategy that most long-sleeve jerseys skip entirely. The sleeves and pockets use a textured fabric to optimize aerodynamics, while body fabrics remain breathable. That combination means you get the ventilation of a summer jersey on the torso where you generate the most heat, and aero-tuned coverage on the arms where airflow actually matters at speed. A newly contoured collar improves comfort and delivers a closer fit at the neck - a small detail that makes a real difference once you're an hour into the drops. If you've been reaching for a short-sleeve jersey deeper into fall or earlier in spring just to avoid the weight of a typical long-sleeve, the Corretto LS is the jersey that closes that gap. Textured aerodynamic sleeve fabric reduces drag where it counts most, keeping the speed advantages of a race-fit jersey intact in longer sleeves3+1 rear pocket layout with full-length YKK Vislon zipper gives you three regular rear pockets plus a zip valuables pocket and an easy-pull tab for smooth temperature regulation on the fly Elasticized silicone waist gripper keeps the jersey locked in place under bibs and through the full range of motion in the saddle | Castelli | Corretto Ls Jersey Men's | Size Extra Large In Ivory/clay-Black
