Men's waterproof jackets for protection from rain in the mountains: hardshell jackets for mountaineering and ski touring, providing an outer layer against rain and wind, and lighter rain jackets for trekking and travel.
A shell is worn over a fleece or down jacket and is the jacket to keep in your backpack when the weather is uncertain. You'll also find Gore-Tex models; some hardshell jackets also feature in the Men's hardshell jackets subcategory.
The best-represented brands are Montura, Karpos, Patagonia, Rab and Arc'teryx.
