Arc'teryx Cerium Vest is an ultralight and warm insulated vest, perfect for minimalists on the trail. It packs easily into your pack and delivers immediate core warmth – whether as a mid-layer in cold, dry conditions or worn alone during breaks and at camp.

The vest combines 850 fill European goose down with Coreloft™ synthetic insulation in moisture-prone areas for optimal warmth and performance. The outer fabric in recycled 15D Arato™ nylon is lightweight and durable, treated with FC0 DWR for water repellency. The lining is plant-based to reduce the use of petroleum.

The insulated collar keeps draughts out, and an adjustable hem combined with a slim fit make it ideal as a layer beneath a shell jacket. Two zip hand pockets and an internal security pocket provide practical storage. The included stuff sack makes transport straightforward.

The Cerium Vest is breathable, windproof and highly compressible – a technical garment for those who want maximum performance at minimal weight.
