Question 1

You are out of the sizes for any colour of this vest.  Will you get more available before Christmas

Seymour, Arc'teryx Guest Services · Accepted Answer

Hi there, thanks for reaching out. While we do not have an exact return date for the Atom Vest, stock will fluctuate as we move through the seasons. We recommend using the “Notify Me” feature, subscribing to the Arc'teryx newsletter for up-to-date information on products, or looking to authorized Arc’teryx retailers for any additional item availability. We hope this helps!

Question 2

Hi, how does this vest work with a climbing harness? How accessible are the pockets when wearing a climbing harness, how does the back length work with the harness, and how durable is the outer material for rock climbing? Thank you.

Beth, Arc'teryx Guest Services · Accepted Answer

Hi Thomas, great question! The Atom Vest works well with a climbing harness thanks to its streamlined design and sleeveless construction, which provides excellent freedom of movement. The hand pockets are generally accessible while wearing a harness, depending on the harness fit. The Fortius™ Air 20 outer fabric offers a good balance of durability, stretch, and breathability for climbing and other mountain activities. While it's designed for regular rock and alpine use, repeated contact with rough rock will naturally cause wear over time. With Coreloft™ synthetic insulation that retains warmth in damp conditions, the Atom Vest is a versatile option for climbing, hiking, and layering year-round.

Question 3

HI. I am wondering if the XL vest is a good fit under the XL Atom Hoody?  I like the idea of having both to cover pretty much any temperature range.  Thanks. Ken

Dante, Arc'teryx Guest Services · Accepted Answer

Hi Ken, thank you for your question. Yes, an XL Atom Vest will fit comfortably underneath an XL Atom Hoody, as the Atom Hoody is designed to accommodate layering. That said, since both pieces provide synthetic insulation through the core, wearing them together will primarily add warmth around the torso. Many guests looking to extend their comfort range in colder conditions choose to pair an Atom Hoody with a fleece or base layer, while those seeking significantly more warmth may prefer a higher-insulation piece such as the Thorium jacket. Ultimately, the best choice depends on your intended activity level and the conditions in which you'll be using the system. We hope this helps.

Question 4

Can you provide chest and length measurements for the size medium and size large?

Seymour, Arc'teryx Guest Services · Accepted Answer

Hi Tahall, thanks for reaching out. Please find your requested measurements for the Atom Vest below:

Size M
Chest Width: 111.70 cm
Center Back Length: 71.1 cm

Size L
Chest Width: 119.3 cm
Center Back Length: 73.6 cm

Question 5

Pensez vous remettre l’ancien model en vente. C’était le model de gilet sans manche qui était un best-seller de la marque. Pourquoi garder la version de ce gilet depuis plus de deux ans alors qu’il ne convient à très peu de monde ?

River, Arc'teryx Guest Services · Accepted Answer

Bonjour, Merci pour votre question. À ce stade, nous ne prévoyons pas remettre l’ancien modèle en vente. Le design actuel est resté plus longtemps dans la collection parce qu’il répond à une direction de mise à jour que nous avons testée, mais nous savons qu’il ne convient pas à tout le monde, notamment en termes de coupe et de proportions. Votre retour sur l’ancien modèle, et sur le fait qu’il fonctionnait pour un plus grand nombre de personnes, est précieux et contribue directement aux discussions autour des futures évolutions de la gamme Atom.

Question 6

Provide the chest, waist and hip measurements for sizes XS and S. How is the vest different from the Proton Vest?

Helio, Arc'teryx Guest Services · Accepted Answer

Hi Macek, thank you for reaching out. Here are the chest, waist, and hip measurements for the Atom Vest Men's in sizes XS and S:

Size XS
Chest Width: 99.1cm
Waist Width: 93.9cm
Hem (hip) Width: 98.4cm

Size S
Chest Width: 104.1cm
Waist Width: 98.9cm
Hem Width: 103.4cm

Regarding the Proton Vest (last offered in the SS24 season) vs the current Atom Vest Men's: The Proton Vest was optimized for high-output activities, with a stronger focus on breathability and temperature regulation. The Atom Vest is a more versatile, everyday insulated layer that prioritizes balanced warmth, comfort, and light weather protection. The Proton used Octa® Loft insulation, while the Atom uses Coreloft™ Stretch 40 gsm synthetic insulation.

Question 7

What size will fit under a size large shell?

Helio, Arc'teryx Guest Services · Accepted Answer

Hi there, thank you for reaching out! The Atom Vest features a fitted fit, which is designed to stay close to the body through the chest and waist, and fits comfortably under outer layers. Depending on your fit preference, a size Large or any smaller size will layer comfortably under a size Large Arc'teryx shell jacket.

Question 8

Må man bruke tørketrommel etter vask eller kan man vaske og henge vesten opp?

Helio, Arc'teryx Guest Services · Accepted Answer

Hei, og takk for spørsmålet! Nei, du trenger ikke å bruke tørketrommel etter at du har vasket vesten. Det går helt fint å henge den opp for å lufttørke. Dersom du likevel vil bruke tørketrommel til å tørke jakken etter vask, anbefaler vi at du setter tromlingen på lav eller skånsom tørkeinnstilling.

Question 9

What is the feel/material on the inside of the vest? Is it fleece or the same material as on the outside?

Luna · Accepted Answer

Hi Ken, thank you for your question! The feel and material of the inside depends on the area of the vest. The side panels are made with a fleece fabric, designed to provide greater freedom of movement and improve ventilation. The front and back panels will feel the same both outside and inside the vest, as they are made with our Fortius™ Air 20 plain weave fabric and have a smooth, lightweight feel rather than fleece. We hope this helps!

Question 10

Could you kindly provide a comparison between the size of the mens medium versus the women's medium? In particular,  the chest/length.  I was informed that the women's cut is now very similar to the mens, contrary to the sizing charts. Thank you.
