When the winter winds are howling, make sure you're warm and comfy with the Arc'teryx Women's Ceres Down Jacket, the warmest jacket made by Arc'teryx. WindStopper helps seal out the gusts at basecamp, and a combination of strategically placed Coreloft synthetic insulation along with 850 fill goose down will keep you warm, even in some of the most inhospitable climates on earth. In cold, alpine environments, this jacket can be used as a perfect stand alone piece, or as an extremely warm mid layer in slightly wetter climates. The jacket has an expedition fit that allows you to easily layer under it for the ultimate in warmth the expedition fit is roomier than Arc'teryx's athletic fit. The elastic cuffs and adjustable waist drawcord help keep the heat in, and plenty of pockets give you ample space to keep the essentials at hand so you're not stuck fumbling through your pack in the middle of a snowstorm looking for your compass.
