Castelli Nano Thermal Cap

A traditionally styled cycling cap that offers extra warmth and water protection thanks to Castelli's Nano Flex 3G material. It fits comfortably under a helmet with minimal bulk, providing excellent warmth on cold days. This is true even for temperatures near freezing and for riders who tend to sweat heavily and therefore need the breathability of Nano Flex. Tip: If you're riding in extremely cold conditions, you should consider the Estremo WS Cap.

Traditionally cut cycling cap made from Nano Flex 3G material for elastic warmth and waterproofing. Foldable ear protection.
