Arc'teryx Atom LT Hoodie Jacket - Men'sis rated4.6087out of5by23.
Rated5out of5byfromSurprisingly GoodI really love this jacket. I especially like that it is very lightweight, and it has unusually long sleeves with a slim fit which is perfect for me because I'm 6' 5" tall at 170 lb. It really is designed as a "mid" layer to go under an Arc'teryx shell. Worn under a shell it adds a layer of warmth that is warmer than most fleece, and it is much more comfortable than any fleece because it does not restrict movement at all. My Arc'teryx shell has under arm vents that line up with the special venting fabric on this jacket, so it is especially adaptable to changing conditions. In the beginning I was concerned that the fabric might be so thin that it would be too fragile, but I've used it almost every day for six months, and it is still like new. Of all the things I purchased in 2013 this is my favorite.

Rated4out of5byfromOnly one thingThis jacket works very well as a layering piece and works ok as a solo piece. The really nice features of this jacket are that it is warm, lightweight, water REPELLENT not water proof (it used a dwr coating not a water proof fabric). The hood is something to get used to, it doesn't have any draw strings just a stretch band that is around the opening when you use it solo is strange because it doesn't move with your head, but when you use it under a hard shell it works amazing. The zipper works well and I love that it comes up to about my lower lip so it keeps most of the wind off your neck. Another thing I really like is the side panels of the jacket are a hard fleece so if you're like me and you heat up a lot when your active it helps keep you cooler so you don't sweat as much. Finally this is an Arc'terx jacket and it holds true to the name the stitching is impeccable and it is a very active fit I can reach in any direction it stays down so you don't get any midsection showing and cold. The only complaint I have about this jacket is that wit has one draw cord at the very bottom hem and it would be very handy to have one at the waist because the one at the bottom tends to ride up if you have it tight and move a lot in it.

Rated5out of5byfromGreat compressible mid and outer layerThis hoodie is incredible. I love it. It's light, compresses incredibly small, and is pretty warm given its weight. So far, I've used it as a main outer layer and as a midweight layer while winter hiking and as an outer layer for casual use. It's great for all of these applications. Fit is spot on, the jacket blocks out wind, and the fleece side panels do a decent job of allowing some exchange of air without making the jacket cold. My main gripe with the jacket is the hood. It has no adjustments so it doesn't turn with your head and will just flop off given a little push. At one point I put the Atom's hood on under my hardshell's well adjusted hood (the weather turned sour) and to my disappointment I couldn't look around because, while the hardshell's hood was adjusted perfectly to turn with my head, the Atom's hood stayed put. When I'd try to look left or right I was looking at the inside of the Atom's hood. Sad. It kept my head so warm. Anyways, I think it was designed with simplicity in order to go under a helmet. -1 star as I think it should accommodate helmetless use better. Fit: I am 6'2" 180 and purchased a large. I can get a light fleece under the jacket with this size, for extra warmth. Might have been able to go medium but I'm not sure it would have been long enough.

Rated5out of5byfromUltra LightThe Atom LT is my favorite mid-layer. This jacket does have a plastic zipper, which isn't a bad thing... it cuts down on weight and it makes the zipper really easy to adjust with only a finger (perfect for climbers), the zipper is also VERY durable. The jacket is insulated with CoreLoft, so its ultra lightweight and warm. It also packs down into the size of a 32oz Nalgene bottle. If you want a 3 season top-of-the-line piece for your outdoor adventures, this is it!

Rated5out of5byfromI am the best girlfriend ever!Bought this for my boyfriend right before he spend a week at HCR, Arkansas in mid-November. He said he was warm and grateful for it at night when temps got between 10-30F. on the plus side for me, he looks fantastic in it and it layers well with all his other clothing. worth the $$!!

Rated5out of5byfromLight and warmPicked this up during the fall sale and had been looking for an opportunity to stress test it. I took a backpacking trip to Yosemite late October of this year and got caught in a day of light snow -> heavy rain -> heavy sleet -> heavy snow. While I wasn't dry, it kept me warm with only my wicking layer under and my pack on top. Needless to say, I am quite satisfied.

Rated5out of5byfromSuper versatileThis product has its place but don't mistake it for a traditional down jacket because its not. The sides under the arm pits don't have down, they have fleece. This jacket will take the place of your soft-shell or service the same purpose. It's best used between 60-45 degrees if you don't plan on layering. Layering will allow you to wear it longer into the winter season. Not water or wind proof Perfect for post workouts, trail runs, and can be used once you pull wet clothes off your body to warm you up. For sizing: I'm 6'0, 205 Lbs, athletic build with 36 in arm length for dress shirts and a large fits me perfect. I love the jacket and recommend it to everyone.

Rated5out of5byfromBest jacket!Amazing, highly versatile jacket. Zipper never gets stuck, it blocks wind great, extremely light but warm. I use it constantly as a stand alone jacket in 40-50 deg weather and it's thin/compressible enough to use as a mid layer under other jackets. I know it says it's not water proof, but It is water repellant and i wear it in light rain no problem.
