Arc'teryx Cerium Vest

Exceptionally light and warm, the Cerium Vest is designed for backcountry minimalists who need core warmth without bulk. It pairs responsibly sourced 850 fill European white goose down with strategically placed Coreloft™ 80 synthetic insulation in moisture-prone zones, using Down Composite Mapping to deliver premium warmth where you need it and resilience where conditions demand. The recycled 15D Arato™ nylon shell is light, durable and finished with a PFAS-free FC0 DWR, while the plant-based Arato™ liner reduces petroleum use without sacrificing packability.

The vest performs as a high-efficiency midlayer in cold, dry conditions or as a standalone during rest breaks and at camp. Its trim, fitted silhouette layers easily under a shell, and the articulated patterning ensures unrestricted mobility. Two zippered hand pockets and an internal zippered security pocket keep essentials close, while an adjustable hem seals out drafts. Compressible and packable, it stows into its included stuff sack for compact transport, making it an ideal companion for hiking and alpine adventures.
