Arc'teryx Cerium Vest 2027 – Women's Mid Layer

The Arc'teryx Cerium Vest is a go-to insulating mid layer for women who move fast in the mountains. 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.

Tipping the scale at just 170g (6 oz), the Cerium Vest relies on 850-fill European white goose down for an outstanding warmth-to-weight ratio, while Arc'teryx's Down Composite Mapping™ positions Coreloft™ synthetic insulation at moisture-prone zones—underarms and sides—so down stays lofted where it counts most. The recycled 15D Arato™ nylon outer is wind-resistant, treated with a PFC-free DWR, and backed by a plant-based Arato™ liner. An articulated, fitted cut keeps movement unrestricted under a shell, and the whole vest stuffs into its own included sack for easy pack-along.

Ideal 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.

• Can I use the Cerium Vest as an outer layer? Yes—in cool, dry conditions it works well as a standalone piece, though it is not waterproof.
• Is the down ethically sourced? Yes. All down is certified to the Responsible Down Standard (RDS) by IDFL, certificate No. TE-99950273.
