Arc'teryx Cerium Men's Insulated Down Vest

The Arc'teryx Cerium Vest is a lightweight, packable insulator built for cold, dry conditions. Its 850 fill European white goose down delivers a high warmth-to-weight ratio, while Coreloft™ 80 synthetic insulation in moisture-prone areas keeps performance steady where down can falter. The recycled 15D Arato™ nylon outer is light and durable, and a bio-derived liner helps reduce petroleum use.

Wear it as a midlayer under a shell or on its own during rest breaks and at camp. A stuff sack is included for compact transport, and the internal zippered security pocket on the left chest keeps small essentials close. The vest is produced in a Fair Trade Certified facility and uses bluesign® approved materials.
