The Zeroweight Dual Dry Jacket features a durable water-repellent DWR treatment that keeps light rain at bay, and highly reflective details ensure you remain visible even in the dark. Inside, the material wicks moisture away from the skin to the outside while remaining breathable, so you stay comfortably dry even during exertion. When the sun comes out, the ultra-light jacket can be quickly packed away into its own zippered pocket.
