The Cotopaxi Women's Fuego Down Vest uses some of the loftiest, lightest down insulation available on the market to provide a surprising amount of warmth despite the vest's light, streamlined look. Not only does its 800-fill down offer lofty warmth, it's also hydrophobic to retain its warmth in the face of snowfall or even light rainfall. Cotopaxi reinforced the vest's weather protection with a water-resistant ripstop shell.
