Castelli Prosecco Tech Long Sleeve Base Layer

Why Do Cyclists Choose the Prosecco Tech Long Sleeve Base? The Castelli Prosecco Tech Long Sleeve Base Layer gives road and gravel riders a performance-oriented solution for cold-weather training that does not sacrifice mobility or comfort. Built with Prosecco Tech polyester fabric, it wicks moisture efficiently while maintaining light warmth against the skin on cool rides. The long-sleeve cut provides full arm coverage for fall and spring conditions when a sleeveless base leaves too much exposed. It layers cleanly under any jersey without adding noticeable bulk. Flatlock seaming throughout the construction prevents chafe and pressure points under bib straps and tight kit. The four-way stretch fabric moves freely through the full range of motion, from the drops to the climb, without pulling or binding. This base layer washes and dries quickly, holding its shape and fit over many seasons of hard use. Best suited for road and gravel cyclists who train year-round and want a reliable base that earns its place in the kit rotation.
