Question 1

What are the dimensions of size S? Is center back length 71.2cm or 72.5cm? Which size is for me? Height 178cm and 63kg

Joseph, Arc'teryx Guest Services · Accepted Answer

Hello Leff, thank you for your question about the Macai Jacket. The center back length for a size Small is 72.5 cm. In terms of sizing, we recommend comparing your body measurements with our sizing chart to determine the best fit, as body proportions and fit preferences can vary from person to person. If possible, visiting a nearby Arc'teryx store to try the jacket on in person can also be a great way to confirm your preferred size: https://arcteryx.com/us/en/stores/find-a-store. We hope this helps!

Question 5

How to layer with the Macai jacket?

Luna · Accepted Answer

Hi Kevin, thanks for your question! The Macai Jacket is a warm, down-insulated GORE-TEX piece designed for skiing and snowboarding. Its regular fit offers comfort and freedom of movement, and layers easily over a base layer and fleece or insulated mid-layer.

Question 6

Has the zipper been improved upon?

Seymour, Arc'teryx Guest Services · Accepted Answer

Hi there, thanks for reaching out. The Macai Jacket has not been updated this season and continues to feature the same WaterTight™ Vislon front zipper and external zippers as the previous version. We hope this helps!

Question 7

Hello,

How much down and coreloft is in this jacket in grams?

In terms of warmth is this more or less warm than the Beta Down or the Therme Down jackets?

River · Accepted Answer

Hello there, the Macai Jacket combines both down and synthetic insulation, but it’s important to note that synthetic insulation like Coreloft™ is measured in grams per square meter (gsm), not total grams, since it’s distributed by fabric area rather than weight. The Macai contains 68.63 g of down plus Coreloft™ 140 gsm. For comparison, the Beta Down Jacket uses 125.87 g of 850 fill‑power down with Coreloft™ Continuous 90 gsm, while the Therme Down Jacket has 97.50 g of 750 fill‑power down with Coreloft™ 100 gsm. In terms of warmth, the Macai is designed as a robust alpine piece, balancing down loft with higher‑density synthetic insulation, so while warmth is subjective, it generally offers more protection than the Therme and sits closer to the Beta Down in overall insulation performance, with the added benefit of Coreloft™’s resilience in damp conditions.

Question 8

Hello, for these measurements :  114cm hip 108cm waist 118cm chest 85cm sleeve; which size is for me. height 164cm and 93 kg. i like the fitted  look. Thank you in advanced Mihai M.

Luna · Accepted Answer

Hi Mihai, thank you for reaching out. Based on the measurements you provided, our Macai Jacket in size Medium is the closest fit:

Hip: 116 cm
Waist: 117.5 cm
Chest: 123 cm
Sleeve: 96 cm.

Since you prefer a fitted look, Medium should work well; it’s close to your measurements and will give a snug fit. If you’d like a bit more room for layering, you could consider Large. Also, you are welcome to order two sizes to try on at home, and return the size that doesn't fit as well.  We offer free returns within 30 days of purchase and delivery, and you can start the process anytime through our returns page: https://arcteryx.com/us/en/help/returns. I hope this helps!

Question 9

Is the fabric for the FW25 MACAI JACKET 3L N40P-X or 2L 100d ePE?

Helio · Accepted Answer

Hi there, thank you for your question! The correct fabric construction for the FW25 Macai Jacket is the 2L 100d GORE-TEX ePE Recycled Nylon, which reflects our latest update to more sustainable materials and increase in durability. The 3L N40P-X was used in older versions of the Macai, so the confusion likely stems from that transition. We’ve flagged the product description page error to our team, and we appreciate you helping us keep the details accurate.

Question 10

For Down Contour.  I understand it as a layer of down stacked ontop of synthetic insulation.
1) Does that mean in the body/upper arms, it is Coreloft 140   Down insulation?  
2) Coreloft 140 used everywhere else?
3) This year's MACAI, same as last year?

Seymour, Arc'teryx Guest Services · Accepted Answer

Hi John, thanks for reaching out. The Macai Jacket features Down Composite Mapping™, which strategically places synthetic insulation (Coreloft™, 140gsm) in areas where moisture may build up and down in other areas for maximum warmth. It features synthetic insulation in areas such as the last baffle on the cuff, around the mouth, underneath the arms, and on the shoulders. Regarding revisions, there have been no updates to the Macai Jacket from the previous season to the current season. We hope this helps!
