My New Hiking Jacket
I was in the market for a new lightweight warm jacket for hiking. This jacket caught my attention, and it nicely meets all my needs. It’s light, warm, stretchy, packs easily, and is breathable under heavy exercise. It makes a nice coat by itself, and is slender enough to be a mid-layer. I wore during a chilly walk in the woods, with a T-shirt under the jacket. Temperatures were in the low 40s, and it kept me nice and warm. Pros: It’s light weight, only 12.5 ounces. It’s nice and warm, for all that it’s light. It squishes down enough to be almost nothing in the pack. Pockets with hidden zippers Wind and water resistant. Even if it does get drenched, the insulation performs when wet Cons: The size seems to be a little small. I normally use a size large, and even then some items kind of hang off me. This jacket is a little tight. The sleeves fit very well, though. I’d suggest getting one a size larger. The drawstring for the hood is on the back, which makes it a little hard for me to cinch the hood down. I anticipate that this jacket is going to accompany me in my upcoming hiking ventures.
Fabric is extremely fragile!!!
First time wearing a backpack with this jacket and the fabric bunched together from normal friction and leave your lovely smooth looking jacket frayed and bunched up tattered and out of shape. I've had the same issue with two Arcteryx items now where I've found the material to be extremely fragile. My conclusion is Arcteryx clothing is for street wear fashion, NOT for any outdoors activities which will expose them to friction or rough surfaces . I feel as though I was misold a product for the outdoors that is not robust enough for even the friction of a lightweight hiking backpack.
Hi there. Thanks for taking the time to share your experience with the Atom Hoody. We're really sorry to hear about the wear you're seeing after using it with a backpack — that’s understandably frustrating. We recommend filling out a Product Service Request form and our team will be more than happy to look into the solutions we could offer: https://arcteryx.com/gb/en/help/product-service/service-request
Versatile and comfortable Arc'teryx
This jacket is a solid go-to for everyday adventures. It’s not too heavy, not too light—just the right balance for staying comfortable. I wore it on some early spring hikes, where it was great to start off with and easy to shed once the day warmed up. I also think it would work really well on chilly, windy days when you need just a bit of extra protection. For reference, I’m 5'10" and 170 lbs, and the medium fits me pretty well. Overall, a solid, versatile jacket for anyone who spends time outdoors.
Outstanding details, fit, and versatility
I grew up backpacking the Blue Ridge with my dad. After a below-the-rim Grand Canyon trip with a friend twenty years ago, I'd let the habit slide until the pandemic started and I began dayhiking local trails again. I'd ironed out every aspect of my gear (hydration, footwear, pack, etc) except clothing; after a few years and three or four different jackets I still found myself uncomfortable regardless of the layers I brought. Turns out between a light merino blend long-sleeved t-shirt and the Arc'teryx Atom, I'm good from 80° down to freezing. This hybrid jacket thing effectively blocks wind while remaining incredibly breathable. I'm used to light-but-bulky down -- but the Coreloft synthetic insulation and fleece side panels combine for effective warmth without getting in the way. For a particularly sunny uphill section a couple weeks ago I was hiking in 45° weather with just a shirt and it would've been nice if this stowed into its own pocket, but it stuffed into the hood well enough to stash neatly in an exterior daypack pocket. And as clouds and a cold front rolled in on the descent, while I found myself wishing I'd brought gloves and a hat, my core and arms were toasty and comfortable. I'm 6'2"/175 and wear a medium. It's got just enough room inside for a midweight fleece if needed but still looks fitted and crisp over a thin long-sleeved base layer. To my massive delight the sleeves were JUST long enough (I usually get a 36" sleeve on dress shirts). The left interior pocket is deeper than expected, and the zipper is nicely unobtrusive.
Outstanding hoody comfort!
The Arc'teryx Men's Atom Insulated Hoody is a versatile and high-performance jacket that has quickly earned a place in regular rotation. The hoody is lightweight, but somehow provides great warmth on those days when it is cold and even rainy. At the same time, it can be worn on more temperate days as it does not cause you to get overheated due to great ventilation and breathability. From a mobility standpoint, the jacket is perfect for everyday wear as well as going on hikes and other outdoor activities. The jacket fits wonderfully and even the hooded area is large enough to allow for a cap or beanie. Overall, this is a great hoody for those looking for something lightweight that has great insulation, breathability, weather resistance, and most importantly is comfortable.
Some issues in a year.
Review of the Arc'teryx Atom Jacket I have been a loyal customer of Arc'teryx for years, and the Atom jacket has been one of my favorites. This is actually my second Atom, and overall, I am very satisfied with its performance. The design, fit, and functionality are excellent, making it a great piece of gear for various outdoor activities. However, I have noticed two significant issues that I believe should be addressed to maintain the high standards of the brand. The biggest problem is with the high collar of the jacket. In less than a year of use, the fabric at the top of the collar has started to show considerable wear due to friction with facial hair. The material has begun to pill, fray, and degrade at an alarming rate. I purchased this jacket in late March 2024, and despite careful use and cleaning, the collar already looks excessively worn. Given the price, I find it disappointing that such an essential part of the jacket wears out so quickly. (See photos). For a brand like Arc'teryx, known for its durability and attention to detail, this is a flaw that should not be present. I strongly suggest that the company consider reinforcing this area with a more resistant fabric or an additional lining to prevent such premature wear. It is frustrating to see an otherwise excellent jacket suffer from this issue, especially at this price point. I sincerely hope Arc'teryx takes this feedback into account, as improving the collar's durability would make the Atom an even better product. Despite this flaw, I still appreciate the jacket's overall quality—but for now, I hesitate to recommend it without reservations.
Hello there, thank you for your detailed feedback and for your continued support of Arc’teryx. We’re glad to hear that the Atom has been a favourite for you, but we’re sorry to learn about the wear on the collar. We appreciate you bringing this to our attention, as durability is a key focus for us. Your suggestion about reinforcing the collar is valuable, and we’ll be sure to pass it along to our design team. If you haven’t already, we encourage you to reach out to our After-Sales team to explore possible solutions. We truly appreciate your insights and hope to continue providing gear that meets your expectations.
Perfectly fitting all weather jacket
Just bought the Atom hoody jacket. The fabric feels absolutely fantastic. I wonder of the outer fabric will stay neat when I'm hiking with a backpack. I wear a size Large and this is, for me, a perfect fit even with my broad shoulders the jacket fits well. What's interesting is the breathability and insulation when you're having a walk or hike. It keeps you warm bit on the other hand, I wore it in a Stadium on a windy and chilly night and I got a bit chilly. I haven't had the chance to test the water resinstancy because it hasn't rained yet. For now a 5* review, but haven't experienced all weather conditions. But overall very happy with this jacket
My Favorite Jacket of 5+ Years
If there's one piece I'll always recommend and/or purchase again-and-again, it's the Atom Hoody. It's been my go-to jacket for nearly every season whether I'm camping, climbing, hiking, backpacking, or going on a walk in the city for the past 5 years. I've tested it against the abrasive granite of Joshua Tree, CA to the sandstone grit of Chattanooga, Tennessee. I've also brought it with me on plenty of international from North America to Europe and Asia. It's never disappointed. The Atom Hoody is warm, comfortable, has a great fit, and is one of the more durable outerwear pieces I've ever owned. It'll always be my first recommendation for anyone looking for an outdoor synthetic hoody.
My new go to jacket.
Bought this for work, and now I use it everyday. It light and keeps you warm even on windy days until the temperature goes below 20°F. Be mindful that this material can get snagged and make a hole easily, but definitely great quality to stay warm. Also I sized up from L to XL. Size L would've been tight around chest and shoulders area.
Nice fit, looks great, but fragile and not warm
The fit is great, it feels good and looks good. But not warm at all and very fragile. I fell while climbing and it ripped everywhere, as if it was made of gift wrap paper. Arcteryx wouldn't replace it, but gave me 40% off a new one. Even at 40% off it's still overpriced, in my opinion.
