cold weather midlayer for activities
- Familiarity: I've put it through the wringer
I have worn the hoody version and prefer it to this version. That being said, however, this is a great jacket and I bought it on sale. The price can't be beat! This jacket is very warm, especially when layered, and still breathes/regulates very well. The perfect midlayer or even standalone layer for any cold day activity. The half zip still looks great and is not hard to pullover on and off. I am 6'3" 200lbs and a large fits well. The athletic fit is awesome (as in all arcteryx pieces) and layers very well. My perfect setup for any cold day in the Sierras is the RHO ltw base layer, this (atom LT) midlayer and either my gamma mx or beta lt shell. Cant beat warm and dry! Durability is unmatched: I've put my atom lt to hell and back and still have no tears or stains! It is warm even on cold days when you aren't active and are stationary, but a heavier midlayer like the atom SV or aphix would be better in those situations.
Great piece of gear

This jacket keeps your warm in almost any condition. Fits great and really conforms to your body and movement. Works well as a base layer.

How does the fit of the Atom LT compare to the Alpha SL Pullover?
I'm 6'5" 210 and wear a Large Alpha SL Pullover when I want a shell without room to layer. I'd like a similarly fitting Atom LT, not sure if that would be a L or XL.
I am 5'11 and 175lbs and the Large was too tight across the chest for me, I would certainly get the XL.
Another Arc Homerun
Arcteryx has nailed the three Fs again- Fit, Finish and Functionality.
Fit- Superbly athletic fit to this little number with great range of motion. It feels like a second skin. A++
Finish- Like so many Arc pieces, the fabric feels great to the touch and makes you want to wear it. (Don't ask me to explain it because I can't but I've had the same reaction to several other Arc pieces. haha) The small things like the quality of the side vents and the wrist closures, makes this piece a pleasure to wear. A++
Functionality- Incredibly warm, almost windproof with enough water resistance to handle light snow, the Atom LT can be used alone or as a layering piece for really heavy climates. I've used it down to the low 30s with a L/S shirt on and been toasty.
This is an action piece though. It only has one inside chest pocket. This doesn't make a difference to me. In fact, any more pockets would ruin the aesthetics.
I highly recommend this for any use, athletic or casual. It's so versatile it could easily be your main jacket for many winter climates. For the price it's almost a steal.
No hand pockets.
Great pullover, It fits good and looks awesome. Its light weight warm. But In the specifications it says this jacket has 3 pockets: 2 hand, 1 interior. Not true!!! there are is only one pocket on the coat! There are no hand pockets just the interior one. So I am probably going to exchange it for the Atom fill zip.

Would this jacket fit comfortably over a ether driclime jacket?
depends on sizing, but yes. My wife has an Atom LT hoodie, and it has room for layering underneath.

I am looking for a lightweight insulated jacket to go over a shell when it get cold when climbing (however not a belay jacket). Will this jacket fit over a shell and not be restrictive?
It fits great underneath a shell, not so much on top, as it's fairly fitted (although I wouldn't say it's restrictive at all; the arms are well-articulated and there's a stretch fabric panel under the arms that give you plenty of mobility). I use mine for climbing when it gets cold and it works great.

"Insulated body, sleeves, and hood provide protection from the elements" Does this really have a hood?
No i does not but Arc'teryx does make the same jacket with a hood, it is a full zippered jacket though.
The description has a lot of mistakes. For example, this is 283 grams in Medium not 375 -- that's for the hoody.
How does this pullover compare to the...
How does this pullover compare to the Patagonia Nano pullover? I am most concerned about its warmth factor weight and face fabric. Are the cuffs and waist hem stretchy? Do they seal in the warmth?
I see a couple main differences. The Atom LT Pullover doesn't have all the external stitching, which is going to be better for shedding moisture and adding durability. The Atom also has stretch fleece panels under the arm which help it fit more closely without being tight, and shed excess heat. As for the cuffs, the Atom uses a really soft stetchy cuff that fits close and isn't tight but certainly seals up better than a thin elastic strip. Warmth-wise, they'll be basically identical, but the Coreloft tends to hold it's loft better over time.
