The Patagonia Men's Bivy Down Ski Jacket offers portable peace of mind when the weather offers nothing but indecision. Insulated with 600-fill-power 100% recycled down–reclaimed from used down products–the Bivy Down Jacket provides the perfect combination of warmth and durability when the day’s plans call for perpetual action in the face of mercurial weather. Its' tough but flexible quilted-nylon-canvas shell looks and feels like cotton and is treated with a DWR (durable water repellent) finish that resists water and abrasion. The lightweight 100% recycled polyester taffeta liner adds a skin-friendly feel and a smooth snag-free glide when worn over layers. Two side-entry handwarmer pockets have a brushed polyester jersey lining; an internal zippered left-chest pocket keeps your keys and phone secure. The stand-up collar and drop-tail hem hold out the cold while you work, and the full-length zipper has an additional wind flap with metal snaps.
