This new revised Atom SV seems very durable, outer fabric is strong and is very warm, warmer than previous versions and has more Coreloft insulation in it. The problem for me is that I also own a previous version, the Atom AR in XL size and it fits much better (trimmer) than this new version in the same size. So I ended up returning it because I didn’t like the fit at all and ordered a Large size instead. Quality from Arc’teryx is still there so I would recommend it for sure, just make sure to maybe try it out at a store first.
I think it’s fair to say that most people miss the fit of the atom AR. This fits sloppily at best. The hood design is lacking as well. The side panels are not simple fleece like the regular atom. They’re more like the proton insulation and outer nylon. I’m an athletic 6’ and this is just too baggy compared to older designs.
Hi there. Thank you for sharing your thoughts on the Atom SV Hoody. We hear your feedback on the fit, hood design, and fabric choices compared to earlier versions, and we’ll be sure to pass this along to our design team as they continue to refine future iterations. Your perspective as someone familiar with past versions is especially valuable, and we appreciate you taking the time to let us know.
Purchased in store, men’s large. I’m 5’9” 210 Pounds. The large fits me great. It’s got a much tougher face fabric than my old Atom AR. The large fits like a L~XL. The xl was very big in the shoulders. Very warm, hood is a bit large but decent. Over all I like it. If you had a large atom heavyweight or atom before try a medium.
I live in Alaska and this has been my go to jacket for years. It’s warm, breathable and handles almost any thing the cold north has thrown at it. I consider it a piece of my must have gear for this area. Love it, and it looks awesome too!
Noticed this on a few products - both Atoms, and the gamma hoody i just bought too - too big of a jump between medium and large. Judging by the rest of my Arc gear the L got bigger, esp in torso.
Hi Nico. Thanks for sharing your thoughts on the Atom SV Hoody. We appreciate your note on the sizing gap between Medium and Large, and how it compares with your other Arc’teryx pieces. Your feedback will be passed along to our product team for review.
gamma jacket. The fabric is technologically advanced and the cutting is excellent. When encountering windy or cold weather outdoors, wearing it can help maintain body temperature.
Better to add windproof feature in this product rest all the same raising the prices unnecessary. Same product with new packaging.

I really like the new Atom SV. I grabbed the black, which sold out very quickly. I bought the original Atom SV 13 years ago and gave it away to a guy on the street who needed it more than myself. I always missed that jacket. I then bought the Atom AR, now here we are full circle it seems back to the SV. This new, revised SV has a fit just as the Thorium has. Which is a looser, more relaxed fit over the previous AR. The length on the arms and down the back are just perfect. I really like the hood fit and the bit of internal stiffness and structure around the brim. Fleece backing in the pockets is just great, but there is one big miss on this jacket. We should have dump pockets, especially for a sever weather version of the Atom! Big miss Arc'teryx! This new SV is EXTREMELY WARM and oh so comfortable to wear. I can tell you that this SV does breathe better that the older AR. I'm happy that this version has Coreloft 120 throughout the entire jacket, just like the original SV. As far as fit, the previous AR had a bit of the 'Michelin Man' fit and feel going on , which really limited mobility, but not so here with the new SV, great mobility here with the new SV. The outer fabric has a great feel in hand and instills confidence that it should hold up to wear just fine, but time will tell. Other than the lack of dump pockets, I really like everything else going on here with the new Atom SV, highly recommended.
