Castelli's RoS Cycling Cap can stick with you through the seasons thanks to a patented system that allows you to seamlessly switch between a windproof, water-repellant front panel and a highly breathable mesh ventilation panel. Simply push up for more breathability and pull down for warmth and/or protection. The protective layer is made of DWR coated Pertex® Quantum fabric for excellent wind and water protection, yet it's still permeable enough to allow sweat to escape. It's layered front construction is still plenty thin and lightweight to comfortably fit beneath a helmet.
