The Rab Men's Khroma Diffuse GTX Jacket is a burly ski shell built for big mountains, plenty of powder, and backcountry touring all season long. Gore-Tex gives rugged waterproof, breathable weather protection that's surprisingly light, thin, and packable thanks to a 3-layer construction. A regular fit lends layerability while articulated sleeves ensure freedom of movement. You can zip off the powder skirt when there isn't any soft snow in sight.
