Built around premium down and a featherlight recycled shell, it slots effortlessly between a base layer and a hardshell on alpine objectives, or stands alone during cool, dry shoulder-season outings.\u003c\/p\u003e\u003cp\u003eTipping the scale at just \u003cstrong\u003e170g (6 oz)\u003c\/strong\u003e, the Cerium Vest relies on \u003cstrong\u003e850-fill European white goose down\u003c\/strong\u003e for an outstanding warmth-to-weight ratio, while Arc'teryx's \u003cstrong\u003eDown Composite Mapping™\u003c\/strong\u003e positions \u003cstrong\u003eCoreloft™ synthetic insulation\u003c\/strong\u003e at moisture-prone zones—underarms and sides—so down stays lofted where it counts most.

An articulated, fitted cut keeps movement unrestricted under a shell, and the whole vest stuffs into its own included sack for easy pack-along.\u003c\/p\u003e\u003ch4\u003eWho It's For\u003c\/h4\u003e\u003cp\u003eIdeal for alpine climbers, ski tourers, and fastpacking women who prioritize a minimal, high-efficiency kit. If you want a vest that disappears into your pack on the approach and earns its keep the moment temperatures drop, the Cerium delivers without compromise. Its hybrid insulation also makes it trustworthy on wetter trail days where a pure down piece would struggle.\u003c\/p\u003e\u003ch4\u003eFAQ\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I use the Cerium Vest as an outer layer?\u003c\/strong\u003e Yes—in cool, dry conditions it works well as a standalone piece, though it is not waterproof.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs the down ethically sourced?\u003c\/strong\u003e Yes.
