Mark A.wrote a review of Arc'teryx Cerium LT Hooded Down Jacket - Men's on January 14, 2019
Familiarity: I've used it several times
Fit: True to size
This is one amazing jacket. I needed a very warm jacket to replace my huge, bulky, old school down jacket, but when this one arrived, I thought I'd made a big mistake. It was as light as a late spring jacket and very thin. How could it possibly keep me warm in very cold temps? On top of that, I'd bought it post-season, so I would have to wait 6-8 months to even test it out.
So it was with excitement and apprehension that I took it out on the first somewhat cold day in D.C. Of course, DC isn't all that cold in December, but since I didn't have a whole lot of confidence in it, I considered it an acceptable starter test. It went fine, so I looked forward to the *real* test: Christmas in MN. And this jacket killed it!
I'm 5'9" and just 132 lbs with 3-4% body fat, and I was wearing only a long-sleeved T shirt and light sweatshirt as a midlayer, and I was quite comfortable on a 10-15 min neighborhood walk in 20 degrees. I felt a little cool when the wind blew, but not uncomfortable, and with a light fleece as a midlayer instead, I bet it would've been fine.
On my last morning, it was only 12 degrees, and I was fine dressed as above. Granted, I was only outside getting in/out of the car and filling the tank of the rental car, but I was surprised not to feel cold.
The fit is a little snug even for me, so I'm not sure a heavy sweater would work well, but you wouldn't be wearing one, anyway, if you're being active.
I haven't had reason to test the hood yet. It isn't adjustable, but it covers everything except your face. The waist is adjustable. There's only one thin inside pocket.
I'm amazed and pleased with this jacket. It may not be windproof for skiing, but otherwise, it will certainly be warm enough down to the teens. Oh, and I love the color I chose (Rigel), which is almost a jewel tone blue, bright without being too young (I'm getting close to retirement). I've gotten compliments on it, in fact. So glad I got it!
