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.
The Atom LT Hoody is a women’s specific insulated jacket designed by Arcteryx to provide superior warmth and comfort for the active outdoor enthusiast who enjoys skiing and trekking in the backcountry. Insulated with Coreloft insulation and coupled with Polartec Power Stretch side panels, the Atom LT Hoody blends superior warmth and mobility without the bulk; it is compressible and packable too! The breathability and wind resistant of this women’s Arcteryx insulated jacket helps it stand up to a variety of inclement conditions.

Nice Jacket 4 petite me

What cannot be seen on the pic is that the sides are not made of insulated material but a stretchy thin fleece material. I am 5'3 & 125 lbs & I fit in a small REI thermal take jackt but Arcteryx medium is the size 4 me. So buy a size larger. Also the sleeves are just a tad too long so if u r tall or have long arms go with another brand like Patagonia(all jackt sleeves are way too long 4 me). Since I am flat chested, you may need to go up a size if you are not.

love it love it

I love this jacket! It is so light but warm especially in the freezing temperatures. It's so light, it doesn't even feel like I'm wearing it. I used to not like winter, but now I do because of this jacket! I'm looking forward to hike more often!
