As light and compressible as functionally possible, the Cerium SL down vest weighs a scant 120g (4.2 oz) but delivers exceptional warmth for its weight. The 850 fill power goose down’s warmth to weight ratio is outstanding, and the tear-resistant, wind resistant Arato™ 7 nylon shell is exceedingly lightweight. It primarily functions as a midlayer, but its efficient warmth and packability makes it an effective standalone for rest breaks, evenings at camp, or emergency bivvies.
Redesign includes two zippered hand pockets, an internal security pocket with a stuff sack, and an adjustable hem drawcord to seal out cold.
