Arc'Teryx Cerium SL Vest - Men's:
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. A minimalist midlayer for cold, dry situations, its lightweight packability also makes it useful as a warming layer for autumn belays, evenings at camp and spring backcountry ski rest periods.
GRAMS ARE SHAVED - The 850 fill power goose down’s warmth to weight ratio is outstanding. The Arato™ 7 nylon shell is a highly compressible fine denier taffeta that provides remarkable durability and windproof properties for exceptionally little weight. Because the Cerium SL is intended as a midlayer, Arc’teryx is able to use sewn through construction to further reduce weight and increase packability. True to detail, the Cerium’s zippers are minimized to reduce weight and bulk.
DISCIPLINED DESIGN - Features and construction reflect disciplined, purpose driven design. Down Composite Mapping™ technology is used to strategically place synthetic Coreloft™ insulation in areas prone to moisture. The single chest pocket includes a removable stuff sack, elastic at the hem seals out drafts, and the collar is carefully patterned to provide coverage while layering comfortably under a shell. A DWR treatment repels light precipitation.
