Welcome to an in-depth Arc’teryx Cerium LT Hoody review that answers all your questions. We’ve got a bit of a down jacket obsession, and the Arc’teryx Cerium is our latest. So, it’s time for a review of the Cerium down jacket. Since we live in the Canadian Rockies down jacket season is year-round. This gives us plenty of time to put the Cerium LT through the paces.
The Arc teryx cerium LT is Arc’teryx’s most popular jacket made with 850-fill down and Coreloft synthetic in areas prone to moisture. The jacket’s fit is athletic and it packs all of the features we look for in a down jacket, yet packs down to the size of a water bottle.
Always designed with a specific purpose in mind, Arc’teryx offers a wide range of insulated jackets, and the Arcteryx Cerium LT is one of its most popular. With premium 850-fill down and Coreloft synthetic in areas prone to moisture, it’s a great option for backcountry use yet still wears well in the city.
In this Arc’teryx Cerium LT Hoody Review, I share my thoughts on the Arcteryx Cerium’s style, weight, warmth, fit, comfort, durability, feature set, and weather resistance.

Arc’teryx Cerium LT Hoody Review
Performance of the Arc’teryx Cerium LT Hoody
Warmth of the Arc’teryx Cerium LT
The warmth on the Arc’teryx Cerium LT Hoody is exceptional, and it’s become a crucial part of my mountain wardrobe. Down is strategically placed through the jacket with “Down Composite Mapping,” which ensures better performance through moisture management and longevity. The composite mapping uses Coreloft synthetic insulation in areas prone to moisture, such as the armpits, sleeves, and shoulders (precipitation). It ensures down does not deteriorate through sweat or precipitation for better performance and longevity.
The jacket uses 3.35 of 850-fill goose down throughout, so the jacket puffs and supplies warmth fast. 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 soft reflective interior. I’ve regularly used the jacket backcountry camping and on alpine summits with temperatures below freezing. The Cerium gets top marks for warmth for a lightweight packable down jacket.
Packability of the Arc’teryx Cerium LT
The Arc’teryx Cerium LT Hoody blurs the line between ultralight and warmth in a cross-section that provides a nice balance. For comparison, the Feathered Friends Eos weighs 10.6 ounces, and the Patagonia Down Sweater Hoody weighs 15.1 ounces. The Cerium weighs 10.8 ounces, making it a little heavier on the ultralight spectrum, but it’s not an anvil by any means.
You can find lighter down jackets like the Mountain Hardwear Ghost Whisperer at 8.8 ounces, but the Cerium uses higher quality shell materials and synthetic insulation for outstanding performance. A stand out feature is the stuff sack that fits slips inside a front breast pocket and packs down to the size of a Nalgene water bottle.
Construction of the Arc’teryx Cerium LT Hoody
Arc’teryx is well known for its high-quality materials and construction. It’s no surprise to find that in the Cerium LT. Stitching, cut, materials, and finishes are all top-notch. When I first tried out the jacket, the quality was apparent, and it looks like a premium jacket. The shell is rated 10-D which makes for an incredibly light outer layer.
Composite Mapping is a smart feature, the synthetic material is vitalized around the shoulders, collar, cuffs, and most importantly underarms. After a full season of use, I’ve noticed no signs of wear or saw any signs of 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 of the Arc’teryx Cerium LT
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 as it does not heat void space. Layering also works well well the slim fit. A shell fits over the jacket while carrying a full backpack. 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.
Features of the Arc’teryx Cerium LT
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 is excellent with 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 of the Arc’teryx Cerium LT Hoody
It’s tough to evaluate the value on the Arcteryx Cerium LT as it is one of the priciest lightweight down jackets on the market. However, if you have the cash to spend on this jacket, it is exceptional. It is a staple in my backpack and is my go-to down jacket. Which means it gets a year-round use since I live 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 it 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.
