Arc'teryx Atom LT Hooded Insulated Jacket -

Weighing in at less than a pound, the Arc'teryx Women's Atom LT Hooded Insulated Jacket is your go-to, lightweight, compressible hiking jacket. Its Luminara fabric is micro-light yet durable, wind-resistant, and breathable. Arc'teryx added Polartec Power Stretch panels on the sides and underarms of the jacket for four-way mobility and 60g Coreloft insulation in the torso, arms, and hood for warmth. A DWR coating helps shed light precipitation and, when the clouds clear out and the weather warms up, this jacket easily compresses into its own sleeve.

The Atom LT has a trim fit to reduce bulk completely for comfortable layering when you hit the slopes. Its insulated Scuba Hood seals out the cold and stays comfortable when you wear a helmet over it. The jersey-knit stretch cuffs are incredibly cozy over your wrists and keep the jacket in place under your waterproof shell.

Arc'teryx Atom LT Hooded Insulated Jacket Reviews:


As you can tell from the title I love this piece. It is truly one of the most versatile jackets that I have ever owned. I wear it climbing, hiking, skiing and just around town. The color I got was the Heron and it's perfect the grey exterior is subtle but the pinky burgundy color on the inside is fun and eye catching.
The fit is slim so if you like to layer under get a size up from what you normally wear. I am 5'4" 34 in the chest and 115 lbs (normally a small) and I got the medium. It ends right below my hip and is not tight at all when I am climbing and that is why I went a size up.
Also it is so light and small. A cool feature is that it stuffs into it's own sleeve so when I am touring and need to save the space for my gear I just quickly stuff it in and it packs down super small!! It's amazing!!!
Warmth is totally not an issue. It's a great layering piece but it does well on it's own too. I wear it around town with a long sleeve shirt and I'm perfect in 20 degree weather. The side panels are thinner so if you do build up some heat, while touring or climbing, it can be released quickly. Also it holds up in light rain and snow really well. The DWR finish helps repel moisture and keeps you dry!
I really can't recommend a better piece to use for all the activities mentioned above.

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.

This extremely high quality jacket is everything they say and worth every dime. The fabric is superior and the outer layer even has a small amount of stretch; add that to the other technical fabric in this jacket and you've got a lightweight, compactible, jacket that moves and breathes with you. The jersey knit stretch cuffs are integrated into the design in a subtle way and are a pleasant surprise that hugs the wrists and is soft and comfy. Flattering and ample body length for coverage and great sleeve length. Fit is true to size. This is one jacket you'll never feel constricted in...super comfortable fit for active use.

This would've been my second Atom LT hoodie but the one that I received is not as pictured--I bought the Heron color which in the photo only has pink in the lining, but the one I got has hot pink piping around the hood. I don't know where this sudden trend in contrast-color trim came from , but I hate it. I'm returning this jacket and waiting for this trend to die.
My previous Atom LT hoody (all black!) is the bomb--warm enough to wear as an outer layer in cool weather and layers great in cold weather. Super comfortable and fits really nicely without bulk or puffiness.

This was a Christmas present for my wife and Santa did good. This is the ultimate mid layer. So warm and light and Arcteryx has figured out how to have a flattering cut on their women's jackets. The wife loves the Malachite color. You can't go wrong with anything from Arcteryx.
