S1 StormShell Jacket

This lightweight, ultra-packable stormshell is versatile enough for emergency deployment, or full days of non-stop rain. Fully-waterproof, seam-sealed construction withstands even the heaviest downpours, while zippered underarm vents give you flexibility & breathability in quickly-changing conditions. Plus, an adjustable hood easily slides over your helmet in a snap, so you don't have to miss a beat when the rain starts beating down.
