Arcteryx Cerium LT Hoody tested and reviewed

Written by

Arcteryx have got an enviable reputation when it comes to winter wear, combining build quality, design and functionality in products you can rely on. When they announced a new insulated jacket in the form of the Cerium LT Hoody we jumped at the chance to put it through a full 3 months of testing in preparation for the winter season.

 What Arcteryx say about the Cerium LT Hoody:

Streamlined in its design, and with an exceptional warmth-to-weight ratio, the Cerium LT hoody works as midlayer or standalone in cool, dry conditions. Premium 850 fill-power down is lofty and resilient, the Arato™ 10 nylon shell provides lightweight durability, and Down Composite Mapping™ strategically places Coreloft™ synthetic insulation in moisture-prone areas. Articulated construction moves with the body, and the insulated StormHood™ provides coverage without compromising range of vision.

Redesigned to include an internal zippered security pocket with a stuff sack, elasticized cuffs at wrist and an adjustable hem drawcord to seal out cold, and an improved fit with longer body length.

Sizes: XS, S, M, L, XL, XXL

Weight: 305 g / 10.8 oz

Fit: Trim fit, Hip Length, Centre back length: 72 cm / 28.5 in

Arcteryx Cerium LT Hoody on test:

I’ve been using and abusing a Cerium Hoody for around three months. I took it to the Swiss Alps in September and due to exceptional Indian summer weather, I couldn’t get near it unless in the evening or stopped on summits.

Now we’ve entered winter with a relatively cold start this November to December in the north of the England, I’ve been wearing it a lot. It’s a great fitting jacket and like many Arcteryx items, it has a slim and tailored fit in small. This means I can layer it under a hard-shell jacket for winter and now it is colder, I’m wearing it as a stand-alone jacket on colder mornings or sat around at camp. The "Hoody" part of the  Cerium LT Hoody is also designed to fit underneath a climbing helmet, rather than over it.

Weighing in at 305g, it has a very small pack size and compresses down to the size of a small water bottle. Weight to warmth is excellent; it lofts immediately once shaken out and until the recent dip in night-time temperatures, I have been using it with just a base layer inside tents when wild camping. The Cerium definitely requires some extra layers once used below -2 degrees at night. With elasticated cuffs and an easy adjust hem it's easy to seal the warmth in.

The only issue I’ve had with the jacket was some down poking through stitching when brand new. This has settled down now and no down coat is completely immune to a touch of down loss over time. The 850 fill power down is not hydrophobic treated, so the jacket does wet out quickly in heavy rain when I was unfortunate to get caught out recently. Pockets are a simple zipped pair at the front and an inner for keys and phone.

Arcteryx have always been priced in the premium bracket and the Cerium is no exception at £300. It is however very stylish and performs very well in cold dry environments. The Coreloft insulation at the cuffs and armpits do stay warm when damp. The DWR coated face fabric has kept light rain at bay and due to the exceptionally light construction of the jacket; it has dried on me really quickly. The Arato fabric is windproof and a recent trip into the hills had a -8 windchill in the morning and the jacket worked well to keep me warm. The Cerium is great on weight and pack size, yet does not skimp on warmth, suiting fast and light adventurers
