Question 1

Why did the sidezipper on the last model of the beta pants get reworked from full length to 3/4 length? Is it still possible to get the model with the full length and what is the main difference between the two models?

Rick, Arc'teryx Guest Services · Accepted Answer

Hello Zelin, thank you for your question. The current Beta Pant was updated with a 3/4-length side zipper to provide ventilation and allows easy on-and-off over shoes and boots. It also features a revised fit and an added thigh pocket compared to the previous version. The earlier Beta Pant with full-length side zips is no longer part of our current collection, although you may occasionally find it on the Arc'teryx Outlet or ReGEAR RESALE websites, depending on availability. Both versions are designed to deliver waterproof, breathable protection for hiking and mountain travel, with the newer model featuring updated GORE-TEX ePE materials and construction. We hope this helps.

Question 2

Men’s Beta Pants.  Would these be suitable for Spring and Summer during warmer climates when heavy  in the rain

Joseph, Arc'teryx Guest Services · Accepted Answer

Hello there, thank you for your question about the Beta Pant. Yes, the Beta Pant can be a great option for spring and summer use in wet conditions. The pant is designed as a lightweight waterproof shell and does not provide insulation, making it suitable for year-round use depending on your layering system. It can be worn as a standalone pant in milder temperatures or layered over other garments when additional warmth is needed. We hope this helps!

Question 3

Side Zippers - what is the length? Written description states "3/4 length" and yet the included photographs appear to show full length zippers. Please clarify. If the zippers are truly "3/4 length" please provide images demonstrating that.  Thank you.

Hi there, thank you for bringing this up. We have updated the product photos and apologize for any confusion this has caused. To clear things up, the current Beta Pant Men's (Style X000010391, 2026 model onward) features ¾-length side zips on each leg, as mentioned in the description and currently shown on the product page. Some of the images previously shown were from an earlier version of the Beta Pants that featured full-length side zips, causing the discrepancy between the photos and product description. This was a mistake on our end, and the page has now been updated. The product you receive will be the latest version with ¾-length side zips. Thank you again for calling this out.

Question 4

There are two models on the photo, one with a pocket on tigh and other without, what am I buying?

Hi there, thank you for pointing this out. We have updated the product page and apologize for any confusion. To clarify, the current Beta Pant Men's (Style X000010391, 2026 model onward) includes a thigh pocket on the right leg, as shown in the updated product images. Some of the images previously shown were from an earlier version of the pant before the thigh pocket was added. The page has now been updated, and the product you receive will be the latest version with the thigh pocket.

Question 5

Hello I’m a 32 inch waist 5,8 HT 172 pounds I would like to know what size do you recommend for the beta pants I don’t like my pants to be baggy but in enough room to wear as a pull over

Helio, Arc'teryx Guest Services · Accepted Answer

Hi there, thank you for reaching out! Based solely on your height, weight, and waist size, it’s tough to recommend a specific size for the Beta Pants since fit preferences can vary. The best way to find the right size is to compare your body measurements with the Beta Pant measurements below. Based on your height and weight, sizes S, M, and L are the most likely options. If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.

Size Small
Waist Width (relaxed -  along the top of the waistband edge): 80.9cm
Thigh Width: 67.7cm
Inseam (short): 76.8cm
Inseam (regular): 81.5cm

Size Medium
Waist Width: 88.5cm
Thigh Width: 72cm
Inseam (short): 78cm
Inseam (regular): 83cm
Inseam (tall): 90.5cm

Size L
Waist Width: 96.1cm
Thigh Width: 76.3cm
Inseam (regular): 84.5cm
Inseam (tall): 91.7cm

We hope this helps!

Question 7

sono pantaloni veri e propri o sono usati come guscio sopra ad altri pantaloni?

Nemo · Accepted Answer

Ciao Gianluca, grazie per la tua richiesta. I pantaloni Beta da uomo sono pantaloni in Gore-Tex resistenti e completi, concepiti per essere indossati come strato esterno, non da usare da soli tutti i giorni. Offrono una protezione impermeabile, antivento e traspirante sopra gli strati di base o intermedi, a seconda delle condizioni.

Question 8

What’s the difference between the beta and alpha pant

River, Arc'teryx Guest Services · Accepted Answer

Hello Zane, the difference between Beta and Alpha pants comes down to how much protection and technical performance you need in the mountains. Beta pant is designed as versatile, all‑purpose GORE‑TEX shells — lighter, simpler, and meant to handle a wide range of conditions from hiking to mixed weather without feeling overly technical. Alpha pant is built for serious alpine and climbing environments, using more rugged materials, more articulation, and features that prioritize mobility, harness compatibility, and durability in harsh terrain. In short, Beta is your adaptable mountain shell for varied conditions, while Alpha is your specialized tool for demanding alpine missions. We hope this helps!

Question 9

does this have the integrated lace hook

Seymour, Arc'teryx Guest Services · Accepted Answer

Hi Nick, thanks for reaching out. The Beta Pant does not feature an integrated lace hook. However, it does include eyelets at the hem that can be used with a shock cord attachment to help secure the pants around your footwear. We hope this helps!

Question 10

Please clarify the Arcteryx statement that “May release plastic microfibres into the environment when washing”. Are these Beta pants PFAS free?

Luna · Accepted Answer

Hi there, thank you for your question and for checking out the Beta Pant! Regarding the note about microfibres, like many technical garments made with synthetic materials, the fabric can release very small plastic microfibres during washing. This is a common characteristic of synthetic textiles and not unique to this product. In terms of PFAS, that's a great question. PFAS (per- and polyfluoroalkyl substances) are a group of chemicals that have historically been used in waterproofing across the outdoor industry. Since 2023, we started transitioning to an ePE membrane and FC0 DWR, which are made without added PFAS. The Beta Pant features our PFAS-free 80d 3L GORE-TEX® ePE fabric with a C-KNIT™ backer. We hope this helps!
