Patagonia Men's Bivy Down Vest. The Bivy Down Vest is a limber but durable outdoor piece made of quilted nylon canvas with a DWR (durable water repellent) finish and insulated with 100% Traceable Down (600-fill-power duck down that can be traced back to birds that were never force-fed, never live-plucked). The two welted handwarmer pockets are lined with brushed polyester, and an internal zippered chest pocket keeps your essentials secure. Full-length zipper has a snap-closure storm flap; stand-up collar and drop-tail hem keep the wind and cold at bay. Hip length.
