Question 1

Does this jacket feature a bottom drawcord at hip level?

Helio, Arc'teryx Guest Services · Accepted Answer

Hi there, thank you for your question. Yes, the Atom SV Jacket has a drawcord at the hem so you can adjust the fit. Hope this helps!

Question 2

I wear a size S, but I find the sleeves a little long. I would like to know if it is possible to shorten the sleeves. Is this recommended?

Helio, Arc'teryx Guest Services · Accepted Answer

Hi there, thank you for your question. We don’t recommend shortening the sleeves of the Atom SV Jacket or making any modifications to the garment. Any unauthorized alteration or tailoring would not be covered by our Limited Warranty and would void future warranty coverage. At this time, Arc’teryx does not offer tailoring or sleeve‑shortening services. We understand that fit can vary from person to person, and information like this is valuable. We will make sure it's shared with our team as we continue to refine our designs and service offerings.

Question 3

I am looking for a hiking jacket for winter conditions in the great smoky mountains. As low as 25 at night and just above freezing during the day. I hike between 20-25 miles a day and move fast.  Is the atom SV a good jacket to consider for my needs?

River · Accepted Answer

Hello Greg, while warmth is subjective, and we don’t assign temperature ratings, the Atom SV Hoody is our most insulated Atom, designed for cold conditions and high-output activities. Its Coreloft™ insulation provides reliable warmth even when damp, while the breathable face fabric helps regulate temperature during fast movement. For long days covering 20–25 miles in the Great Smoky Mountains, layering will be key—pairing the Atom SV with a moisture‑wicking base layer and a weatherproof shell when conditions turn wet or windy will give you adaptable protection. If you prefer a lighter option for warmer days, the Atom Jacket may be worth exploring, but the SV offers the most warmth and versatility in the Atom family for demanding winter hikes. We hope this helps!

Question 4

Is the Atom SV suited for low activity warmth like down jackets? Would I be able to comfortably use it at 6am in my cold car? I'm looking for an alternative warm midlayer since puffers don't fit my style.

River · Accepted Answer

Hello there, the Atom SV is designed as a highly versatile synthetic insulated midlayer, built to perform exceptionally well during high-output activities where breathability and durability are key in colder temperatures. While warmth is always subjective and can vary from person to person, many find the Atom SV provides reliable comfort even in lower-activity settings, such as sitting in a cold car early in the morning. Unlike down, synthetic insulation is optimized to retain warmth when damp and to regulate temperature during movement, but it can still serve as a cozy alternative if puffers aren’t your style. For maximum comfort in static, cold environments, layering with a shell or pairing it with other insulation can enhance its performance.

Question 5

Since atom sv was updated with a more streamlined fit, does it now close to regular atom jacket which is fitted??

Luna · Accepted Answer

Hi there! Thank you for reaching out. We’re excited to hear about your interest in the Atom SV Jacket! The Atom SV has a regular fit, designed for freedom of movement and easy layering. The Atom Jacket, on the other hand, has a trimmer fit that sits closer to the body. Here’s a quick comparison of both jackets in size Medium:

Atom SV Jacket
Chest width: 123 cm
Waist width: 114 cm
Hem width:  116 cm

Atom Jacket 
Chest width:  115.8 cm
Waist width: 106 cm
Hem width:  110.5 cm

If you prefer a trimmer fit like the Atom Jacket, we’d recommend going down a size. If you’d like more room for layering, your true size should work well. You are also welcome to place an order for two sizes to try at home, and return the size that does not fit. We offer free returns within 30 days, and you can start the process anytime here: https://arcteryx.com/us/en/help/returns. We hope this helps!

Question 6

Which midlayer is warmer, Atom SV or Cerium, in most conditions? And in general, which is the warmest midlayer you have in your collection?

River · Accepted Answer

Hello Nick, thanks for your question. When comparing warmth between the Cerium Hoody and the Atom SV, it really depends on your environment and activity level. The Cerium uses down insulation, which offers exceptional warmth-to-weight and compressibility—ideal for cold, dry conditions and lower-output pursuits. The Atom SV, on the other hand, features synthetic insulation that performs better in damp environments and during high-output activities, with faster dry times and more consistent warmth when wet. It’s also the warmest option in our Atom collection, designed to deliver maximum thermal performance while maintaining versatility as both a midlayer and a standalone piece. Each excels in different scenarios, and the best choice comes down to how and where you plan to use it.

Question 7

Is this jacket “packable”, e.g. stuffs into it’s own pockets?

River · Accepted Answer

Hello Rick, no, the Atom SV Jacket is not considered “packable” in the sense of being designed to stuff into its own pocket. While it is relatively lightweight and compressible for an insulated jacket, it does not feature a built-in stuff sack or pocket-stow design like some other technical layers.

Question 8

Is the dwr pfas free

River · Accepted Answer

Hi Krisz, great question! Yes, the DWR (Durable Water Repellent) finish on the Atom SV is PFAS-free. We use an FC0-based DWR, which is a non-fluorinated alternative designed to minimize environmental impact while still offering effective water resistance.

Question 9

Is jacket good to wear underneath a Beta AR in terms of layering. When I purchase the same size for the Atom SV will this fit underneath the Beta AR (Stormhood)?

Sophie · Accepted Answer

Hi Rodin, great question! Yes, the Atom SV Jacket is designed to layer comfortably underneath a shell like the Beta AR Jacket, and we recommend sticking with your regular size for both pieces. The Atom SV features a streamlined, regular fit that allows for freedom of movement while still accommodating layers. For reference, here are the key measurements for each item in size M: the Atom SV has a chest measurement of 123 cm, waist of 114 cm, and a center back length of 72.5 cm. The Beta AR offers a regular fit, with a chest of 123 cm, waist of 113 cm, and a longer center back length of 77 cm, making it well-suited to layer over the Atom SV without feeling restrictive. We hope this helps clarify how the two jackets work together in terms of fit and layering. If you’d like any further assistance with sizing or measurements, feel free to reach out, we’re happy to help! https://arcteryx.com/ca/en/help/contact

Question 10

Does it has the same fit as the atom heavyweight (now sv) vest with hood, but simply without the hood? Or is the fit more steamlined/snug?

Sophie · Accepted Answer

Hello, great question! The Atom SV Jacket and Atom SV Hoody both feature a regular fit, designed to offer comfort and freedom of movement through the chest, waist, hip, and thigh. This cut provides shape while layering easily over or under other pieces, so we recommend choosing your usual size for either style. The Atom Vest, however, has a fitted silhouette; it’s tailored to sit closer to the body, minimizing bulk and moving with you. It’s ideal for layering over base layers or under shells. Depending on your comfort preferences, you might consider sizing up for a more relaxed feel, or stick with your regular size for a more streamlined fit. If you're unsure, we offer free returns within 30 days, so you're welcome to order multiple sizes for comparison. We hope this helps!
