As wonderful as it would be if the weather in the mountains was always fair, serious hikers know that’s not always the case. That’s why Rab made the Downpour Plus 2.0 Jacket. Constructed from lightweight, breathable, and recycled Pertex Shield 2.5 Layer waterproof fabric, this packable piece offers ample coverage when skies turn gray. The regular fit wears easily over t-shirts and midlayers alike, while the articulated sleeves mean you can scramble to the summit unrestricted.
