Size: Free Color: Navy (close to black) Only tried on. Thin, light, highly breathable, waterproof, and compact when not needed. It's like an umbrella, protecting your head in sudden rain, a hat you can use all season. Well, you'll still get soaked without a matching outer layer... Like the coat and pants, it uses ripstop fabric made with strong nylon yarn, which is resistant to tearing. It's water-repellent, with a PU laminate and membrane treatment on the back, creating a 2.5-layer fabric. Seam tape is applied to the seams, so you probably won't get wet in the rain (in my personal opinion). The lining uses breathable mesh, and the inside of the head area is equipped with pile material.
