Arc'teryx Cerium Hooded Jacket vs Patagonia Fitz Roy Down Hoody

The Cerium Hooded Jacket is the lighter, more packable choice for fast alpine and cold-weather layering, thanks to 850-fill down and a fitted cut. The Fitz Roy Down Hoody is heavier and roomier, with a helmet-compatible hood and more pockets, so it suits colder resort days and casual wear. Reviewers praise Arc'teryx for warmth-to-weight and trim fit, and Patagonia for durability and a more relaxed fit. Both use responsibly sourced down and recycled shells.

  • Choose the Arc'teryx Cerium Hooded Jacket if you want the lightest possible down layer for climbing, ski touring or travel and you prefer a fitted cut.
  • Choose the Patagonia Fitz Roy Down Hoody if you want a roomier fit, a helmet-compatible hood and more pockets for resort skiing or everyday cold-weather wear.

What reviewers say

Arc'teryx Cerium Hooded Jacket

Owners treat the Cerium as a benchmark ultralight down midlayer: warm for its weight, very packable and well cut for layering. The recurring complaints are the fragile thin shell and the price of replacing it after snags, plus down performance in wet conditions.

What people mention
  • Warmth-to-weightPraisedOwners say it is very warm for how little it weighs and packs.
  • Face fabricCriticisedThe 15-denier shell snags and tears on rock and branches, according to owners.
  • FitMixedThe fitted cut layers well under a shell but leaves little room for thick layers underneath.
  • Wet weatherCriticisedDown loses loft when damp, so it is not relied on as a wet-weather layer.

Patagonia Fitz Roy Down Hoody

Owners praise the Fitz Roy Down Hoody as a light, warm layer with useful pockets and a hood that fits over a helmet. Complaints center on the thin shell fabric and a roomier-than-expected fit.

What people mention
  • WarmthPraisedOwners say the 800-fill down keeps them warm for its low weight.
  • WeightPraisedReviewers like how little it weighs and how small it packs.
  • HoodPraisedThe hood fits over a climbing helmet, which owners value on alpine routes.
  • PocketsPraisedUsers like the zippered chest and handwarmer pockets plus the large internal pocket.

Questions and answers

Which is warmer?
The Cerium has higher fill power and a trim fit that traps heat efficiently, but the Fitz Roy has more total insulation and a roomier cut. For dry cold, the Fitz Roy feels warmer; for warmth per ounce, the Cerium wins.
Which is better for skiing?
The Fitz Roy, mainly because of its helmet-compatible hood and extra pockets. The Cerium works as a midlayer under a shell but its hood does not fit over a helmet.
Which packs smaller?
The Cerium. It weighs about 300 g against roughly 485 g for the Fitz Roy and compresses smaller, which matters for climbing and travel.
Is the Cerium worth stepping up to?
If low weight and packability matter most, yes. If you want a tougher shell, a helmet hood and more pockets, the Fitz Roy covers those better.
How do the fits compare?
The Cerium is fitted and sits close to the body, so size up if you plan to layer over a fleece. The Fitz Roy is a regular fit with more room through the body.
Which handles damp conditions better?
The Cerium, because it uses Coreloft synthetic insulation in areas prone to moisture. The Fitz Roy is all down, which loses loft when wet.
