Moosejaw Staff Pick - Greg, Moosejaw Secret Headquarters

The Arc'teryx Men's Cerium SL Jacket is a light down jacket for fast climbing and hiking adventures and even traveling to new places. The Cerium is insulated with 850 fill power goose down for warmth, combined with a composite construction which places Coreloft (a synthetic insulation) at the shoulders, collar front, and wrists to deter moisture build-up. The SL stands for superlight, making this trim fit top the lightest down jacket in the series at 6.5 ounces. The hand pockets features low profile zippers and the whole jacket stuffs into the included stuff sack for travel, emergency use, and maybe even a quick nap. The Thisela nylon outer shell remains incredibly lightweight for its strength and is coated with a durable water repellent finish for the light rain or snow days. If you're looking for speed, the light weight Cerium SL certainly won't slow you down.

Rated 5 out of 5 by from Versatile I've been using this jacket for 9 months now and it's become my favourite piece of gear because it's so versatile. I've used it trekking in Nepal, skiing in mild conditions out west (-5 -10C) and extreme cold in the east (-25C), and travelling in a cool European spring (10-12C). I even wear it to run errands and around the house as sweater in the winter! I've also carried it on flights for occasions when I have to go outside to catch a shuttle transfer in the winter or as back up when I arrive at my destination in case my checked bag is lost. What makes this jacket so versatile is that it's extremely light; very compressible; warm, but not too warm; and has a very low profile or silhouette so it doesn't fit like a puffy. The longer fit of the back also ensures the jacket never rides up too high. I've worn it as a mid layer under trim fit and athletic fit shells. I've also worn it as a top layer in cool dry conditions while hiking. While hiking I've pulled this out of my pack during short rest stops, thrown a shell over it in windier locations, or worn it as mid layer under a shell in the morning when it's been colder (-10C). I usually wear it all day under a shell when skiing and vary my base layer depending upon the temperature or add a vest if it's extremely cold. While it's intended as a mid layer, I've used it as a top layer for hiking and haven't had any problems. The outer material has held up under a backpack and I've never gotten a tear or any sign of wear in the shoulders, waist or back. If it's windy, the wind will go through this jacket. It's not designed to be a wind stopper. The exterior layer is thin and the down baffles are very narrow requiring a lot of stitching where the wind will penetrate. Keeping this in mind, if you're on a multi day hike, you'll have a shell with you any way. It's of course not water proof, but I've found the DWR finish kept me dry in misty weather or light precipitation, but I wouldn't rely on it for anything more. With down jackets, people are always concerned about how much down leaks out. Even though the exterior of this jacket is very thin and there is a lot of stitching for the baffles, I can count on one hand the number of feathers that have poked through in 9 months of almost daily use. I've just worked them back in without any problem. I usually use jackets with synthetic insulation as my mid layer or light outer layer. I bought this jacket because I was looking for something which was lighter and more compressible than synthetics. Plus I didn't need a thicker down jacket that was designed for colder conditions. This jacket has met my needs perfectly.

Rated 4 out of 5 by from Exceptional warmth and a breathable piece This down jacket has a couple of points that really separate it from other down pieces: 1. It's one of the tighter weaves so down loss is minimized. Having said that I still see minor down loss to the piece with use as my other jacket I see bits of down after wearing with it as a kid layer 2. Compressibility- I can fold this jacket into a tiny pouch the size of my fist and fit it in my pack for touring, or even camping when it gets cold. 3. Warmth - for its size nothing can beat the warmth. I literally can wear just this and a base layer and I'll be quite warm in close to freezing weather. In -10 up on the top of whistler I'd say I'll be fine with a hardshell to block the wind and rain with high energy output 4. Elastic cuffs - some of the best designs I've seen. It wraps around my waist and wrists tight enough but not too tight. I hope they will last with use. Having said all that the one downside with down is moisture really destroys it's warmth, so I always wear a base layer of synthetic and merino wool to try not wet the down with my sweat. High energy output activities on a wet day I think the atom lt would be a better choice.

Rated 5 out of 5 by from Mid layer at it's best! It's my mid layer for downhill skiing and a lightweight jacket to grab for short trips to town. Very warm for being so thin and light, amazing at times. For skiing I wear one base layer from Arcteryx or Patagonia of different thicknesses, followed by this jacket for the mid layer, and finally an outer Gore-Tex shell jacket for snow/wet conditions or a Spyder jacket for sunny/bluebird days. Great purchase! This jacket will be replacing aging and well used ski bum clothing. Never know, some ski bunny might buy me a beer when she sees me wearing such a stylish jacket. There is hope at last!

Rated 4 out of 5 by from Great Jacket This is my second down jacket, my first was a Rab microlight. The Arcteryx Cerium SL is a great piece of kit, at less than half the weight of the Rab it seems to provide the same levels of warmth. People have criticised the shell material for lack of breathability but I have not really encountered this issue as of yet. The shell material is paper thin as you'd expect so if you are at all heavy handed with your gear I'd probably recommend you look at a more durable option. I'm quite careful so havn't had any problems yet. I have, to date on the hill used the jacket mostly as Arcteryx intended which is as a thermal layer to be carried in your pack and donned during rest periods or around camp. For this it is outstanding as it is effectively a weight penalty free method of carrying an insulative layer. I have also worn it on its own and under a Neo shell jacket out and about where it has performed well for casual use. Fit is mostly great other than the fact it does seem to bulge outwards around the mid-rif some times (I don't have a gut ;-) So, overall a great piece, a weight penalty free insulative layer that compresses down to the size of a large beer can!

Rated 5 out of 5 by from Great purchase! This jacket is a lot thinner than I expected, but it still is a very warm jacket. With a sweater or sweatshirt underneath, you are totally comfortable in temps as low as 15-20F.

Rated 5 out of 5 by from Very warm, well cut, stylish. I absolutely love this jacket. This is my second Arcteryx product and I am very glad I bought this for a middle layer - it is far warmer than I expected for such a light item. It wears close to the body and doesn't allow any cold air to creep up my back or into my sleeves. The styling is awesome and you can feel the quality just by touching the fabric. I have already told several friends about how much I enjoy the Cerium SL.

Rated 5 out of 5 by from Great for packing light I'm a landscape photographer and often trecking to remote locations at early dawn or towards the end of the day when temps begin to drop. I was looking for something with enough warmth to keep me comfortable at the summet of mountains, while still being compact enough to carry on the way up without taking up much space. This is jacket fills my needs perfectly.

Im worried this jacket runs smaller than most Arcteryx jackets. 5'9", 38" chest, 145lbs. I wear a small in everything Arcteryx makes, normally. Think a small will be too small? Want it for mid layer and solo piece

Asked by: Sawyer
Thanks for the question! The Cerium does have unique sizing. I would go with a Medium since it is a trim fit. It may be a little roomier in the shoulders, tho. Hope this helps!
