Insulated with 600-fill-power Recycled Down, reclaimed from used duck and goose down products, the Bivy Down Jacket provides the perfect combination of warmth and durability when the weather offers nothing but indecision. 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. Side-entry handwarmer pockets are lined with brushed polyester, and an internal zippered left-chest pocket keeps your keys and phone secure. The stand-up collar, drop-tail hem and full-length zipper with an internal wind flap hold out the cold while you work. Hip length.
