The rugged shell is rated at a 25,000 mm water column, with fully taped seams to keep out downpours and sleet, from short outings to long days outside. The adjustable storm hood shields your face while leaving room for a headlamp, ready when night falls early in autumn and winter. Every detail is made to serve performance and movement. Armpit zippers regulate airflow during activity. Adjustable waist, chest, and cuffs allow the jacket to adapt to your body and layering without holding you back.
