The Capo Men's GS SL Wind Vest is a lightweight, packable wind vest that's deployable at a moment's notice when strong winds and inclement weather threaten your daily ride. Its E4 Luminescent Membrane is wind and water resistant, keeping you warm and dry during cool, transitional months. What makes this membrane stand out is its luminescent design that's highly reflective for boosted visibility when you're riding in low light conditions. Its Micro fine Mesh provides extra breathability when you're working up a sweat on high cadence training rides. Other key features include a dropped rear hem for extra coverage in the dropped position, as well as three rear pockets for holding energy gels and extra layers within easy access.
