The Men's Supercharger Insulatedis a lightweight insulated jacket which combines natural and synthetic down for warmth and versatility. Great for alpine pursuits in cold or wet climates, the Supercharger has hydrophobically treated insulation and has a tough ripstop nylon shell, which stops down escaping and resists scrapes. In targeted areas (chest, shoulders, arms), the Supercharger Insulated has Dry Q Active fabric, a durable and stretchy, performance fabric which promotes freedom of movement and resists heavy rain.
