Don't get caught in a downpour without the Rab Downpour Jacket. This waterproof outer layer is built for comfort and has all the practical features you'd expect from a quality rain layer — zipped pockets with storm flaps, adjustable hood and cuffs, and pit zips to regulate heat. The Downpour packs into its own left-hand pocket, so you can carry it with you at all times, just in case those clouds roll in.
