The Arc'teryx Atom SV Hoody is ¥59,400 and 490 g (men's). It is the warmest insulated hoody in the Atom line and part of the fall 2026 new arrivals. I name it my pick for people who stand still for long stretches on a cold ridge.
The Gear Nerd's Pick
The insulation is Coreloft 120 (120 g per square meter), thinned to 100 g only in the side panels where you get hot when moving. So when I pick an insulated layer for cold-season hiking, where you get cold the moment you stop, I count the SV for the ventilation it keeps.
Key points
- 490 g, ¥59,400. 135 g heavier and ¥9,900 more than the Atom Hoody
- Insulation is 120 g/m² in the body and 100 g/m² in the side panels. Synthetic fill that keeps insulating when damp
- ¥121 per gram. Cheaper per gram than the Atom Hoody (¥139)
Atom SV Hoody price and weight: ¥59,400, 490 g
The Atom SV Hoody (men's) is ¥59,400 incl. tax and weighs 490 g. Sizes run XS to XXL in 3 colors: Cloud, Bracken and Black. The model number is X000009902.
It is the warmest model in the Atom line, formerly called the Atom Heavyweight Hoody. It is an insulated softshell designed for cold-weather hiking and low-to-medium-effort days in the hills.
How I judged it
The first thing I checked was the amount of insulation. The Atom SV has 120 g/m² in the body, the thickest in the line. Next I lined up weight and price. At 490 g it is 135 g heavier than the standard version and ¥9,900 more. What I weighed was whether to add that 135 g. I still recommend it because it costs ¥121 per gram, lower than the standard version's ¥139. It suits people who walk cold ridges where they stop for long stretches.

What is different about the Atom SV Hoody's side panels?
Here is where I get excited. The insulation changes by zone, so it is warm without getting stuffy. The body carries 120 g/m² to warm your torso, while the full-length side panels are thinned to 100 g/m². The idea is to let heat out only where you get hot when moving.
This season the panel shape was reworked to fit a man's build, and the water-repellent finish no longer uses PFAS. The outer fabric is a ripstop that blocks wind well, and the insulation is a synthetic fill that handles damp better.

| Model | Weight | Price (incl. tax) | Per gram |
|---|---|---|---|
| Atom SV Hoody | 490g | ¥59,400 | ¥121 |

Arc'teryx Atom Hoody Men's
Lowest price on Rakuten: ¥44,550 (as of 10/20). Prices vary by shop, up to ¥53,800, and change daily.
RecommendedSee it on Rakuten IchibaFor the option that combines insulation and shell in one jacket, see the Beta Insulated review. If you want something lighter to wear as a mid layer, the Kyanite Hoody review fits too.
Which color and size of the Atom SV Hoody?
It comes in three colors: Cloud, Bracken and Black. Sizes run XS to XXL with a regular fit, and the back length is 72 cm in M. It is cut with room to wear under a hardshell, so your usual size works if you are layering inside.
Where it falls short
At 490 g it is clearly heavier than the Atom Hoody's 355 g, and the ¥9,900 gap is not small. The thicker insulation also means it runs hot on days when you keep moving. Arc'teryx itself positions it for low-to-medium-effort activities.
Who is it for?
It suits people who stop for long stretches on cold-season ridges, for breaks or photos. It also suits anyone who wants a layer that works under a shell or on its own. If you put weight first and keep moving, the standard Atom Hoody or the SL is another route.
