Montane Phase Lite Waterproof Jacket review in a sentence: This Gore-Tex–armed outer layer stows away into a small, light and easy-to-carry package when not in use but performs a big, important job with quiet confidence when called into action.
As every outdoorsy person on the planet will tell you, the secret to staying comfortable, dry and warm in the wilds (and especially at any sort of significant altitude) is to adopt the layering system, where you start with a good base layer, throw a mid-layer (like a great fleece) on over that, and finish up with a waterproof shell layer.
