Question 3

Will this jacket fit comfortably under the Naya shell? Since the Naya is cropped too, I’m mainly wondering whether the insulated jacket is short enough that it won’t hang noticeably below it.

Beth, Arc'teryx Guest Services · Accepted Answer

Hi Sarah, great question! Yes, both pieces are designed with a cropped silhouette. In size S, the Naya Shell has a center back length of 54.5 cm, while the Omineca Short Jacket has a slightly shorter center back length of 52.9 cm. Because the Omineca is shorter than the Naya, it should layer comfortably underneath without hanging noticeably below the shell. They pair well together for a clean, streamlined look. We hope this helps!

Question 5

What is the denier/ripstop rating on the face fabric for this jacket? How durable is it designed to be?

Seymour, Arc'teryx Guest Services · Accepted Answer

Hi there, thanks for reaching out. The Omineca Short Jacket is designed as an ultralightweight down jacket for multi day hikes. It features a recycled stretch nylon fabric with an abrasion-resistant ripstop construction. The face fabric is a 47 gsm recycled nylon mini ripstop. We hope this helps!

Question 6

Is it waterproof or resistant?

River, Arc'teryx Guest Services · Accepted Answer

Hello Ayse, thank you for reaching out. The Omineca Short Jacket is water‑resistant, not fully waterproof. It’s treated with an FC0‑DWR (PFC‑free Durable Water Repellent) to help shed light precipitation, but it does not have a GORE‑TEX membrane. This means it performs well in drizzle or brief exposure to moisture, but it isn’t designed for sustained or heavy rain.

Question 7

Chaud jusqu’à - quel température?

Amelie, Arc'teryx Guest Services · Accepted Answer

Bonjour Gina, merci pour votre question. Nous n’attribuons pas de cote de température à nos vêtements, car le niveau de chaleur ressenti varie considérablement d’une personne à l’autre selon plusieurs facteurs, comme le niveau d’activité, les conditions météorologiques, les couches portées et la tolérance individuelle au froid. La veste Omineca est conçue pour offrir une chaleur ciblée grâce à une construction thermomappée qui aide à optimiser la régulation thermique selon les différentes zones du corps. Elle est également légère, compressible et facile à transporter, ce qui en fait une excellente option pour les activités à faible intensité, les randonnées de plusieurs jours ou comme couche isolante de secours. Le duvet, quant à lui, offre généralement un excellent rapport chaleur/poids ainsi qu’une grande compressibilité, ce qui en fait un choix privilégié pour les conditions froides et sèches ou les activités à faible intensité. Pour obtenir des conseils sur la façon d’optimiser votre système de superposition selon différentes conditions, nous vous invitons à consulter notre guide des couches : https://arcteryx.com/ca/fr/shop/layering-guide/. Nous espérons que ces informations vous seront utiles dans votre choix.

Question 8

Is this jacket packable?

Joseph, Arc'teryx Guest Services · Accepted Answer

Hello there, thank you for your question about the Omineca Short Jacket. While it does not come with a dedicated stuff sack, it was designed to be highly packable. The jacket utilizes lightweight down insulation and compresses well for storage in a pack when not needed, making it well suited for backcountry use, hut trips, and multi-day adventures. We hope this helps!

Question 9

What is the down fill weight for a size L and XL please?

Joseph, Arc'teryx Guest Services · Accepted Answer

Hello there, thank you for your question about the Omineca Short Jacket. The down fill weight is 72.91 g for a size L and 78.19 g for a size XL. We hope this helps!
