Premium warmth with feather-light design

Arc'teryx Cerium Jacket Men's blends a lofty 1000-fill European grey goose-down with a streamlined, lightweight silhouette. The down is certified by the Responsible Down Standard (RDS), balancing high warmth with ethical sourcing. In daily wear you feel a soft, cushiony warmth that moves with you, without weighing you down during commutes or quick climbs.

Smart insulation for variable conditions

Down Composite Mapping combines high-loft down where warmth matters with Primaloft synthetic insulation in moisture-prone zones. This targeted approach helps maintain comfort when humidity or light dampness appears, keeping the core warm while staying agile and compact for layering.

• Down-rich core delivers warmth with low bulk
• Primaloft in critical zones helps retain warmth when conditions shift

Durability, weather protection, and fit

The shell uses 10D recycled Pertex Quantum mini-ripstop nylon—ultralight, abrasion-resistant, and downproof. A PFAS-free FC0 DWR finish helps repel moisture, while the helmet-compatible StormHood provides added warmth in gusty weather. Sewn-through construction reduces weight and minimizes down shift for consistent performance.

• 10D recycled Pertex Quantum mini-ripstop shell is ultralight and durable
• FC0 DWR finish and PFAS-free formulation promote moisture resistance
• StormHood is helmet-compatible for added warmth during gusty days
