Part of Rab’s lightweight and functional mountain running collection, the Men’s Vital Windshell Hoody offers packable protection from the wind—a key piece of gear when you’re putting miles behind you in the mountains. This compact jacket packs into its own internal stuff sack so you can stow it in the pocket of your running shorts or hydration vest. The outer fabric blocks biting gusts, while the adjustable, elasticated hood is designed to stay put, even when the wind really starts cranking.
