As the lightest down jacket in the Arc'teryx Essentials collection, the Men's Cerium SL Down Jacket offers incredible warmth packed within an extremely lightweight and compressible jacket. Ideal for chilly backcountry adventures, this down jacket features Down Composite Mapping with strategically placed 850-fill European grey goose down for maximum warmth, and Coreloft 40 and 100 synthetic insulation an ideal blend of warmth and moisture management. The ultra-light Thisela (nylon) face fabric won't weight you down on minimalist backcountry missions, and its DWR finish sheds light snow showers when you're skiing down your favorite face. In addition, the jacket's elastic rear hem seals out cold drafts, and the zippered hand pockets include a stuff sack for easy stashing.
I always wanted any product from Arc'teryx, but now I see, that it's not what I was hoping!
