Exceptionally warm and lightweight the Filson Featherweight Down Vest is insulated with traceable, ethically-sourced goose down—offering the highest warmth-to-weight ratio of all natural insulations. Built with an ultralight ripstop shell, it’s highly compressible, taking up little room in a pack or bag. The shoulders and pockets are reinforced with panels finished with durable water-repellent to protect against light rain and snow. Outfitted with a two-way front zipper and interior storm flap to seal out the wind. Snap handwarmer pockets are lined with cotton Moleskin.
