Arc’teryx Cerium Down Hoodie Jacket Review

warmth

The warmth on the Arc’teryx Cerium LT Hoody is exceptional, and it’s become a crucial part of my mountain wardrobe. The jacket uses 4 ounces of 850-fill goose down throughout, so the jacket puffs and supplies warmth fast. It’s a cozy jacket that we love to wear.

Synthetic down is strategically placed through the jacket through “Down Composite Mapping.” The composite mapping uses Coreloft synthetic insulation in areas prone to moisture, such as the armpits, sleeves, and shoulders (precipitation). It ensures the actual down does not deteriorate through sweat or rain for better performance.

The synthetic down does not seem to compromise warmth as there is ample supply of the premium down where it counts. In cold temperatures, the Cerium down jacket feels right at home with a plush feel and a soft reflective interior.

I’ve regularly used the jacket during backcountry camping and on alpine summits with temperatures below freezing. The Cerium gets top marks for warmth for a lightweight, packable down jacket.

Packability

The Arc’teryx Cerium LT Hoody strikes a perfect balance between ultralight and warmth, with a weight of 11.8 ounces. It may be slightly heavier than other ultralight options, such as the Feathered Friends Eos at 10.6 ounces. It’s still far lighter than the Patagonia Down Sweater Hoody at 14.8 ounces.

The Cerium accomplished this with its high-quality shell materials and synthetic insulation for exceptional performance. The exterior shell is a 15-D ripstop nylon making the jacket incredibly light. A standout feature is its packability, with a convenient stuff sack that fits inside the front breast pocket and compacts down to the size of a Nalgene water bottle.

Construction

Arc’teryx is well known for its high-quality materials and construction. It’s no surprise to find that in the Cerium LT. Stitching, fit, materials, and finishes are all top-notch. When I first tried out the jacket, the quality was apparent, and it looked like a premium jacket. The shell is rated 10-D, which makes for an incredibly light outer layer.

Composite Mapping is an intelligent feature. The synthetic material is vitalized around the shoulders, collar, cuffs, and, most importantly, underarms. After several seasons of use, I’ve noticed no wear or insulation loss, with feathers coming through the shell. The jacket has even spent plenty of time in and out of the stuff sack, where the most significant wear-and-tear would occur.

Fit

The Arc’teryx Cerium LT is a “trim fit,” which is certainly true in real life. It’s a jacket cut for an athletic build that feels slim against the body and moves well. It’s easily the best fit I’ve had in a down jacket and lends well to performance. The slim fit performs very well as the body has to work less and does not heat void space.

Layering also works well well the slim fit. A shell fits over the jacket while carrying a full backpack. Pictured above is the jacket under Arc’teryx Beta, a bomb-proof pairing that feels ready to tackle the notorious weather of the Faroe Islands. That being said, if you have a frame that is not athletic, the trim fit may not fit your body well.

Finishes such as the waist cinch, adjustable hood, and elastic cuffs integrated into the sleeves round out the fit. All work well and do an excellent job keeping the cold air out. When it comes to fit, Arc’teryx nailed it, and I have zero complaints.

Feature Set

The Arc’teryx Cerium rarely leaves you wanting with its feature set. I say almost because the hood is not helmet-compatible. However, in temperatures cold enough to where that is an issue, it’d be best to reach for a jacket more robust than a lightweight down jacket. The hood has excellent head coverage and a StormHood cinch that performs reliably.

A standout feature is the interior breast pocket that holds the stuff sack with a small loop. I’ve lost more than a few stuff bags over the years, and this is a nice feature that ensures I never lose the sack. It also makes for an easy adjustment of layers when on the mountain or trail. Two exterior pockets that work well for storing odds and ends or keeping your hands warm.

Value

It’s tough to evaluate the value of the Arcteryx Cerium LT as it is one of the priciest lightweight down jackets on the market. However, it is exceptional if you have the cash to spend on this jacket. It is a staple in my backpack and is my go-to down jacket.

This means it gets year-round use since I live in the Canadian Rockies. It may be worth considering where you spend most of your time outside to place a value on the jacket. I’ll easily spend 100+ days a year in a down jacket, will you?

You get a lot of jacket for your money, and they will outperform cheaper value models like the REI Co-op Down Jacket 2.0 or the Patagonia Better Sweater. The REI Jacket is 1/3 the price, and the Patagonia Better Sweater is 2/3 the price point. It’s questionable you’re getting three times the jacket.
