An ambitious jacket that manages some weather on its own and that crushes conditions under a hardshell.
The Arc'teryx Women's Atom LT Jacket is the skinniest full-jacket member of the Arc'teryx Atom family, but don't let the sleek profile fool you. The Atom LT packs a wallop of warmth when mid-winter marathon training finds you outside pounding snow-packed pavement in Minot, North Dakota. This slick little number also works well under a shell when the weather dictates more hardy protection.
Coreloft 60 insulation leans towards the lighter side of the Coreloft cabal, and does not cover every inch of your upper body. Deliberate design puts the insulation where it matters most: your core, arms, and shoulders. Along the jacket's sides and under your arms, you'll find Polartec Power Stretch with Hardface technology. This four-way stretch fabric accommodates your every move, and Hardface technology ups the ante on abrasion resistance. The non-insulated panels also help the jacket breathe so you don't become the steaming carne asada inside a toasty synthetic insulation burrito.
As with all members of the Atom family, the Atom LT can be shoved into its own sleeve for packing efficiency and economy of size when space is a premium. DWR coating fortifies the water-repelling aspect of the shell fabric, while the air-permeable polyurethane layer enhances the shell's wind resistance. Articulated elbows and underarm gussets give your arms free range of motion, whether you're dancing in the firelight or fighting for the final pitch. From dawn patrols to winter running to shoveling the driveway after a late March dump—whatever your preferred poison, the Atom LT will keep you warm through the bitter end.

My favorite jacket!!! :D
- Familiarity: I've put it through the wringer
- Fit: True to size
I love love love this jacket!!! Here's some reasons why:
- incredibly comfortable
- super light
- compresses down to pretty darn small
- articulated elbows (no tight feeling when bending the arms or bunching on the inside of your elbow)
- dries fast
- small wrists (keeps out wind and great for layering)
- smooth zipper (Arc'teryx quality everything)
- fits and looks great
This jacket is super awesome for a few different activities. I bought it initially for wearing with my drysuit (on winter river trips) because the slim sleeve design fits well under a drysuit with gasketed wrists, but then I found out once I had it, it's the best cold weather running jacket I've ever worn! (By cold, I mean cold).
I am 5'5", 105 lbs, measurements are 30x24x34 and I went with a small. I could've done an XS (I tried them both on) and I went with the small for the extra length in the torse, but either worked fit wise.
