The R-01 Skin LS is built for riders who want pro-level aerodynamics even when the sleeves get long. This isn't a bulky winter jacket; it’s a high-performance technical layer designed for riding hard in cooler conditions. If you’re smashing a chain gang or a late-season crit, this jersey keeps the drag low and the intensity high.Same pro-level spec as our short sleeve jerseys, built for cooler conditions. The long sleeve adds arm coverage without sacrificing breathability or freedom of movement: a slim fit that performs as hard as you do, whatever the season.
