Whether you're roaming through rainy forests or over blustery summits, the Helly Hansen Roam 2. 5L Jacket will be along for the ride with waterproof and windproof protection from the elements. Its burly nylon shell resists abrasion on rocky paths and overgrown trails, and keeps you dry when steady rains spend most of the day disappearing and reappearing. This shell is also windproof and breathable, which means that your internal temperature won't be too cold or warm as you push up winding switchbacks. Plus, it packs into its own pocket when blue skies return and you want to revel in the sunshine (while it lasts).
