One of The North Face's warmest jackets, the Men's Prism Optimus Jacket has tons of 700 fill down insulation, an insulated hood, and a lightweight nylon ripstop exterior that sheds wet snow and freezing rain. The Men's Prism Optimus is fully featured with a laminated hood brim, a napoleon chest pocket, inner water bottle pockets, a hideaway hem cinch-cord, and internal security pocket, hand pockets, and a stowpocket. A great Summit Series style for winter expeditions or for just headed to work on incredibly cold days.
