Is the Cerium Hoody warm enough on its own?

In dry cold it works as a standalone jacket for moderate conditions. In wind, wet or deep cold it is designed as a midlayer under a shell.

How does it compare with the Cerium LT?

The Cerium Hoody is the current version of the Cerium LT line, keeping the 850 fill down and Coreloft mapping. Check the specific model year for changes in fabric and fit.

Does the down stay warm when wet?

Not fully. Coreloft synthetic insulation covers moisture-prone areas, but the down itself loses loft when soaked. Keep it under a waterproof shell in wet weather.

Can the hood fit over a climbing helmet?

Yes. The StormHood is insulated and helmet-compatible, with a single-pull adjuster.

What comes in the box?

The jacket and a removable stuff sack attached inside the inner pocket.

How should I wash it?

Use a down-specific detergent, wash gently and tumble dry low with dryer balls to restore loft. Avoid fabric softener.

About the Arc'teryx Cerium Hoody

The Arc'teryx Cerium Hoody is a light, warm down hoody. It can be worn as an alpine midlayer or on its own. It is insulated with responsibly sourced 850 fill European white goose down, and Coreloft synthetic insulation is used in areas prone to moisture.

The body is made from recycled 15D Arato nylon, which is light and durable. The insulated StormHood is helmet-compatible and adjusts with a single pull. An integrated stuff sack makes the jacket easy to pack.

The fit is fitted and trim. It stays close to the body through the chest, waist, hip and thigh, so it layers over first layers or under outer layers.
