This men's insulated vest comes from our line of Orvis PRO fishing apparel, the most technologically advanced outerwear we've ever built. Using a combination of technical fabrication and action-specific design, Orvis PRO apparel takes on the elements and provides the protection necessary in even the harshest environs. The Men's PRO Insulated Vest uses body mapped insulation to provide optimal temperature control through a wide range of activity levels and environments. 80g PrimaLoft® Gold Active insulation protects the body's core, with weightless, highly packable warmth ideal for active pursuits. Polartec® Alpha® (80g), designed for Special-Ops teams, regulates body heat and moisture through the side panels, allowing the vest to be comfortably worn through a wide range of temperatures and activities. The outer is Ultralight 20D stretch nylon ripstop with a special coating that provides tear, wind, and water resistance. Zippered, fleece-lined hand-warmer pockets, zippered chest pocket for storage, and internal zippered security pocket that doubles as a stuff sack. High-quality YKK® zippers and DWR (Durable Water-Resistant) coating.
