Western Mountaineering insulated the Flight Down Vest with the loftiest down out there to make it incredibly light, highly compressible, and surprisingly warm for alpine treks, mountaineering expeditions, or more casual camping trips that are still cold. A rating of 850-fill doesn't mean this down insulator is the biggest, heaviest, or warmest puffy out there, but it does mean this vest will be lighter, loftier, and more compressible than down vests with lower fill ratings that are just as warm. To continue keeping it light, Western Mountaineering made it out of the lightest ripstop available. All together, this vest only weighs around six ounces, making it an excellent addition to backpacks that can't afford much space or weight.
