Arc'teryx Cerium Hoody Jacket 2027 – Insulator

Description

The Arc'teryx Cerium Hoody is a packable insulating mid-layer built for alpine climbing, ski touring, and backcountry travel. It performs as a standalone piece at camp or as a core layer under a shell, offering premium warmth in a minimal package designed to handle the demands of technical mountain terrain.

At the heart of the Cerium is an 850-fill European white goose down, complemented by Coreloft™ synthetic insulation placed strategically via Down Composite Mapping™ in moisture-prone zones like underarms and cuffs. The recycled 15D Arato™ outer fabric is both wind-resistant and treated with an FC0 (PFAS-free) DWR finish, while a bio-derived 20D Arato™ liner reduces petroleum use without compromising packability. The trim fit pairs well under a hardshell, articulated patterning keeps movement unrestricted, and the insulated StormHood™ is helmet-compatible with a single-pull adjuster. Two zippered hand pockets, an internal security pocket, and a stuff sack round out the package.

Who It's For

The Cerium is made for alpinists, backcountry skiers, and ski tourers who need serious warmth that doesn't weigh them down or bulk up their pack. If you're stopping at a belay, waiting at a col, or transitioning mid-tour, this jacket earns its place the moment the wind picks up. It rewards those who move fast and light but refuse to compromise on warmth when they stop.

FAQ

• Can I wear the Cerium as an outer layer? Yes — the wind-resistant, DWR-treated shell handles light conditions well, though it's optimized for use as a mid-layer beneath a waterproof shell in harsher weather.
• How does the down stay effective when it's damp? Down Composite Mapping™ places Coreloft™ synthetic insulation in areas most exposed to sweat and moisture, so your warmth stays consistent even when conditions aren't.
