Keeping your noggin protected when you're outside is a good idea. This Gore-Tex Cap from Norse Projects is an ideal way to do so when you're expecting to get wet. The classic six-panel hat is a multi-layer design, with a Gore-Tex membrane and a lightweight 50 Denier outer fabric with a PFCec-free DWR coating. It's held together with fully waterproof seams and has an adjustable nylon back strap, mesh lining, and a reflective logo at the rear.
