Function lies at the heart of the Outdoor Research Radar Storm Cap. Waterproof, breathable, and fully seam-taped, this street-styled cap is built with double-layer 100% nylon Ventia fabric which shields you from both sun and rain. The TransAction headband wicks away moisture to keep you cool and dry. The mesh tricot lining feels super-soft next to the skin and lets skin breathe to prevent overheating. The fabric-covered brim folds up for easy storage in your pocket or pack. Imported.
