Rated 5 out of 5 by from Awesome Jacket I use this jacket for everything and I mean everything. From back country snowboarding and camping on Vancouver Island BC Canada to using it as a mid layer while Snowmobiling North of 60 in -20 to -30 degrees Celsius weather or just kicking it around town when the temp is down. This jacket has been a go to jacket for me for about 2 seasons and it is still going strong, it insulates well, vents well and it has a DWR coating that keeps light rain and snow out. Over all an Outstanding Jacket you will never find anything else like it, I highly recommend this one to everybody that dose anything active outside in the winter. Try it you will love it.

Rated 5 out of 5 by from THE quintessential synthetic sweater There are so many glowing reviews of the Atom LT, it's hard to believe they might be true. Let me save you the time: they are. Functions well as a mid layer, while active in frigid temperatures (think 0-10º F), or as an outer layer (belay jacket style) for the rest of the year. Lightweight but durable, Arc'Teryx nailed the face fabric with this one and the inner fabric is incredibly smooth and comfortable. Fleece in all the right places for that perfect fit and to help you while heating up in the winter and an inner pocket are just a couple of the details that make this piece perfect. Top-notch quality and attention to detail are presumed.

Rated 5 out of 5 by from Great Product. I have four Arcteryx jackets, recently purchased this one. Coreloft insulation is a really great product, especially when its mated to a great brand like Arcteryx. I spent a year deployed to eastern afghanistan in the mountains. Base altitude was 7800ft, we were issued a 7 layer system and the beefy jacket had coreloft insulation, great product (drys fast and keeps you toasty). I'm a manager for a large railroad now and wore this in about 28 degree weather during a derailment for 10+ hrs. The hood is great, as well as the the cut of the jacket. The hood does a great job keeping your head and neck warm, even to the point where you don't have to wear a beenie.

Rated 5 out of 5 by from Awesome Jacket. Not for Arctic Explorers. I got this jacket for hiking and general use in moderate-cold temperatures. For that purpose, it is perfect! I generally run kind of warm, but the insulation on this jacket seems just right for my needs (~30-40 degrees).,,,,The jacket is extremely lightweight, and packs up extremely well for those trips with lots of temperature fluctuation. It fits me really well, with a nice, slim fit. I am 5'10" and about 155 pounds and got a small, which works perfectly. Sleeves are just the right length, and never move from my wrists!,,,,The only thing I haven't had much chance to test is the DWR, but from the light showers I have had the jacket in, I have never gotten wet.

Rated 5 out of 5 by from Way warmer than you think! I have a patagonia down sweater and I feel as though this is just as warm if not warmer as a mid layer. Since down requires loft to stay warm I think this beats it out as a mid layer as compression doesn't really affect the insulation. It's lighter and more packable as well. The face and lining fabric slide over and under layers quite easily and the fit is quite slim—arcteryx "athletic" is more of a base layer fit and if you've got a 40-42 chest this will be very fitting. Even though it's athletic fit the articulation and cut do not impede movement any and the side stretch material does wonders with breathability.

Rated 5 out of 5 by from Very high performance Jacket First of all, I would like to say that the silverstone pictured on the websites is very misleading. In reality, it is a a good looking shade of cold gray. This is the jacket that I have always been looking for, the fleece stretch panels on the sides of the jacket are very good at breathing and as a result, the internal temperature of the jacket is well regulated. The zippers are very smooth to allow you to zip and unzip with only one hand, though the zippers aren't locking, so it may unzip when stress is applied. All in all, this is a beautiful jacket, from the impeccable stitching to the insulated front zipper wind guard, Arc'Teryx has really thought this product out.

Rated 5 out of 5 by from Utility Piece Fit is true to size. I'm a beefcake at 5'11'' 215. Thick not pudgie. XL fits perfectly. Underarm gussets are wonderful, jacket does not pull up when I have my arms above my head. Draw-cord in the bottom hem is a nice feature. The Atom LT lacks a draw-cord in the hood, Would be a nice feature but not a deal breaker. Just remember this for windy conditions.,,Enough room for a base layer but not overly bulky.,,Warm enough on a cold day but not too warm for cool days for casual use.,,Great technical midlayer piece when on the hill or in the backcountry. ,,,,II think my favorite part about this jacket is the cuff.,,,,

Rated 5 out of 5 by from My go-to jacket for any chill occasions! Probably the best jacket I've ever owned! I live in Florida, so I wish I could wear this more often. I brought the Atom LT to Wyoming as my main jacket, it held up way beyond belief. My friends nagged me that I would get soaked and that it would tear once I took a hard fall. Through the five straight days of skiing, I had taken many hard falls. I actually thought I had a concussion at one point, and had possibly torn my ACL. Nope! The Atom kept me warm, the outer part of it got moist from snow melting on it, but it never seeped through, so I always remained dry. I can see this jacket lasting me for years to come!

Chest / Bust - Measure around your chest / bust, holding the measuring tape under your armpit.

Waist - Measure around the natural waist, which is often the narrowest part of your waist.

Hip - Measure around your hips at the widest part.

Sleeve Length - With your arms in a slightly bent position, measure from the center of the back of your neck, along the length of your arm, to the wrist.

Inseam / Pant Length - From a standing position, measure from your crotch to your ankle.

Head Circumference - Measure the full circumference around the widest part of your head.

Hand Length - Measure from the tip of your middle finger to the base of the palm.

Hand Width - Measure the circumference of your hand around the knuckles, excluding the thumb.

• Please note that all the info provided above refers to body measurements, and NOT the dimensions of the garment.


Next to Skin Fit - These snugly-fitting garments are made with stretch fabrics to fit next to the skin to enhance moisture management and thermal efficiency. Garments in this fit category when constructed using Arc'teryx's heavier-weight AR and SV fabrics also perform very well as mid layer pieces, and users should consider selecting a larger size to accommodate a base layer underneath if the intention is to use this layering system as a mid layer option.

Trim Fit - Trim-fitted garments share the motion-friendly traits with Arc'teryx "Athletic" fit garments, but are patterned with lower volume for reduced bulk. These close-fitting pieces layer well under other garments.

Athletic Fit - This is the "Arc'teryx Standard" fit. These complete patterns utilize anatomical shaping and gussets to enhance motion by minimizing excess bulk. Easy layering under or over each item extends seasonal versatility and comfort.

Relaxed Fit - Relaxed fit garments rely on higher volume patterns and a reduced amount of articulation to offer roomy mobility.

Expedition Fit - Cut roomier than the Arc'teryx Athletic fit and suitable for winter/extreme conditions, Expedition (XPD) fit garments are cut larger to accommodate multiple layers without binding or restricting movement.

• You can find the fit type and additional fit info for Arc'teryx styles in the product description FEATURES and SPECIFICATIONS.
