This is an odd image, i know. It shows you the material that is on the inside of armpit heat release panel. Kind of like a low pile velour for lack of a better description. Its great, light and breathable.

I See the Light

This garment deserves all the hype it receives. A feather weight heat maker so thin that it appears to be translucent.

It has a nice armpit heat release panel as show in the image below.

I also have the hoody version and both Atom LT's are awesome they provide a ton of warmth for how light they are (in volume and weight). It's great to jog in as a top layer, ski in (on cold days) as a mid layer, ski (on warmer, dry days) as a top layer, and to wear around town. I wear it on air planes and if I get hot, the jacket stuffs into it's own sleeve and becomes a lumbar roll (do not stuff it too tightly or the fabric around the armpits will bunch up).

This is my favorite jacket in my closet and by far the most useful.

Ever layer one Atom LT over another? Sometimes my LT Hoody isn't enough and I wish it were warmer but still had the side panels to vent during exercise. Horrible idea or work well in anyone's experience? Used to work at Patagonia and we'd always double-down with two down jackets when things got colder. Thanks.

I've worn my Atom AR over my Atom LT for more warmth, but that was just out and about. Found it to be nice. Don't have experience doing that with very active activities, but I have found that it's quite comfortable.

Atom LT and Atom AR

I have both the Atom LT and the Atom AR. I guess this review points out what I feel are the major differences and some similarities. The Atom AR has more Coreloft insulation, and of course makes the jacket warmer. I use it for trekking or just around town on fairly cold days. Awesome warmth. I've found the LT is good to about the high 40s to around 50 degrees before I start feeling cold, just when used for casual use. I have the LT in the carbon copy color, which is a very dark gray, bordering on black and my Atom AR is a dark gray, too (The LT is much darker) I really like the stretch panels that are part of the Atom LT jacket. As the AR has a loser fit, those panels aren't as necessary, but I do wish the AR had them. Great jacket. Glad I have both for different uses and different temps. As an aside, both are size XL (I purchased before a lot of weight loss) and they fit fine, but not snug.

So Comfy

  • Familiarity: I've used it several times

Really comfy. Really warm when used under a 3L shell. As usual, arcteryx cut - if you're not super fit and skinny, it probably won't fit.

Have to disagree with expectations for fit. I am 5'9, 175 and built athletically but definitely NOT skinny - a LG fits me like a glove. I just wish it had zippered outside chest pocket. Love it.

I was shocked - but pleasantly surprised - at 6'2" and 195 lbs and semi-fit body that I can wear the Atom LT in a size XL, with room for a fairly decent amount of base layers. Never thought I'd be able to wear a "trim fit" Arc'teryx jacket.
