Product Description Item No.   10251202

The Arc'teryx Men's Atom LT Hoody is an insulated jacket for your mid-layer in cold weather climbing, hiking, or skiing. The Atom is packed with Coreloft, a synthetic insulation that traps air to keep you warm, while remaining lightweight and compressible. Coreloft insulation is also hydrophobic, so if you happen to get wet, it'll dry quickly to get back to keeping you warm. The trim fit stays close to your body and ends at the hip, maintaining the heat and allowing you to move freely. The jacket is articulated throughout, with fleece panels for extra stretch as well as breathability. The outer shell is made with Tinthan, a 100% nylon fabric, that is lightweight and durable. Treated with a durable water repellent throughout, a light snow will bead up on the surface of the jacket so you can brush it right off. An insulated ScubaHood fits under a helmet and an adjustable cord keeps your peripheral vision intact. Fits under your hardshell without complaint, or if it's too hot, tuck the whole jacket into it's own arm sleeve and throw it into your pack for later. I'm no physicist, but I bet good old Albert would've loved this jacket.

Rated 5 out of 5 by from Excellent light-weight and versatile jacket This is a really, really good piece of design and craftmanship. It can be used in the city, with a classy touch or on your mountain ascent. I live in the arctic circle in Norway, and it is perfect for spring and autumn usage. I love the details and quality. The seams are perfect (some jackets have bad seaming) and the insulation is wonderful. The materials are so comfortable that this is my "go-to-jacket" for most cases. For colder conditions (-10>) I use heavy-duty down-jackets. If I would recommend this jacket? YES. The "bang-for-buck" is really good with this jacket! If you are obsessed with quality and form-factor - this is the jacket for you!

Rated 5 out of 5 by from Smooth Not sure why, but there was skepticism to first believe that this jacket could be as good as everyone claimed since it doesn't feel like anything; however, another convert there is, as this is as warm and comfortable as advertised. Wearing only a Motus short sleeve underneath, it felt normal in temperatures around 0 celsius and didn't cause overheating even at 10 celsius. This is much superior than anything else in terms of lightness, pack-ability, windproof and even water resistance. It's feels like smooth sleeping bag material, except softer. The jacket drapes well and matches Arcteryx's sizing's. Unfortunately, this jacket may just replace all others...

Rated 5 out of 5 by from Perfection achieved Purchased this out in San Diego while attending a skydiving school knowing that it was the winter and that I would need something else to add to my layering system. It was the last one left, as usual with most arc'teryx products, and for good reason. I made 22 skydives with this on and never felt too hot and was never cold. It held up to 130 mph winds as I free fell and kept on coming. Then on my off time I climbed two peaks in southern arizona. The desert scrub, briar, and cactus plants never mananged to tear the jacket. I was simply amazed with the product that this company has put out.

Rated 5 out of 5 by from Another stellar design I picked this bad boy up as insulation under my Alpha SV jacket. When I first put it on, I found the hood to be very odd. No way to cinch up the opening so I was at first unimpressed with that part of the design. Otherwise a great piece of equipment that is really light and surprisingly warm given its size. Back to the hood issue, I put the Atom on, then I put my Alpha SV jacket on, and since I live in Vancouver and it rains for 8 months of the year, I put the hood on the Atom up and then put the hood of my Alpha jacket on and it all made sense. I have never in my life owned an umbrella and when it rains I just put my hood on and thus am 100% waterproof.

Rated 5 out of 5 by from You won't want to take it off I've had a lot of outdoor gear over the years. I have always been a fan of down filled jackets. I am a total convert. it is warm, soft and light. It compresses really easily in a pack and for travel. I have since bought a second LT and an SV. The LT is great for 3 season activities - hiking, camping, ski touring in warmish weather and running on a cold day. I tend to use the SV around town (Vancouver) all winter and under my goretex shell for downhill skiing. Both are also terrific on a light rainy day - doesn't soak through unless it is pouring down. Love the fit, hood, everything about it.

Rated 5 out of 5 by from Buyer beware... I have a serious complaint about this jacket. Let me explain (briefly): I bought this jacket as part of my outdoor layering system, expecting to use it with a baselayer and a shell out on the trail / crag when the going got cold. However - and this is a real problem - since I bought it I have pretty much worn it every day. I wear it to work, I wear it under my motorcycle jacket, I wear it out in the evening and I wear it to walk to the shops. The problem: this jacket is super light, super warm, super comfortable and an annoyingly good cut/fit with really urban styling. The hood is uber comfortable. The fit is fantastic. The fabrics feel amazing. It weighs far less than any of my other daily wear jackets, and is more comfortable and better looking than them too. Don't buy this jacket if you intend on leaving home without it.

Rated 5 out of 5 by from Best piece of clothing I ever bought And I bought it before I started working here! For Vancouver's climate, it's a perfect winter/early spring jacket. Even on cool nights in early summer. The warmth to weight ratio is awesome...almost like down, without the feathers. Warm, light, and surprisingly water resistant. It's also the perfect jacket to pack away when snowshoeing or hiking up a mountain...then pull it out once you've reached the top and start to cool off. It packs super small into its own hood. I also took it with me on a trip to Mexico...it made a great pillow on the plane, and a warm jacket available once I got off the plane in Vancouver!

Rated 5 out of 5 by from Great Mid and Outer Layer I've had my Atom LT Hoody for over a year now and it has become my go-to piece for Mid and Outer layering. From temps in the mid 30's and up the Atom is a great outer layer, comprable to Marmots Zeus or Patagonia's Down Sweater. When the temp drops below 30, or I'm on the slopes, the Atom pairs nice with my Arcteryx Theta AR shell. The two of those combined are the perfect combination of warmth and breathability. The one minor complant is on windy days with minimal activity, a breeze can cut through the Polartec Power Stretch side panels, but if you layer properly, or are doing a high intensity activity that the jacket is designed for, this is a very minor issue. Overall the Atom LT Hoody is awesome. I recommend it to anyone looking for a versitle Mid/Outer layer insulator.
