Not waterproof
Be careful this pant is not waterproof . There is no difference betwin this pant and my jeans . Both not waterproof
Hi there, we are sorry to hear about the issue you are experiencing with your Beta AR Pant. The pants were designed with N80d Most Rugged 3L GORE-TEX PRO to keep you dry in a wide variety of activities. We recommend washing and reapplying DWR on your pants to reactivate the waterproofing. If your garment looks or feels dirty or is no longer beading water, give it a wash. With Heavy use (e.g. heavy activity) – wash every 5 to 8 days of use. With Light use (e.g. day to day) – wash every 10 to 20 days of use. Additional product care instructions can be found on our Product Care page. https://arcteryx.com/ca/en/help/product-care/?intcmp=product-care If you are still experiencing issues with your Beta AR Pant after cleaning it, we suggest filling out a Product Service Request form, and our representatives will assess how we can assist you. https://arcteryx.com/ca/en/help/product-service/service-request
Sturdy, well made and worth the money
I went with 32R Black (I am 182cm, 72kg) The pants fits nice and well, sits a little higher than a "normal" pair off pants, which makes it comfortabel if your wearing regular pants with a belt under. Combined with the Alpha AR, i feel secure from the weather and the peaces does well in combination. Beta AR feels sturdy, especially the bottom part. There is clearly room for skiingboots, which is an upside when putting on the pants with boots on. Would be nice if there was a cord for the "shoeattachment" included. The colour on the knees is a little touchy, when its comming in touch with rocks and alike. All in all, very happy woth the purchase.
Not warm
Not warm when using bicycle . I felt frozen on my bike
Hi Amirtoo, we are sorry to hear that the Beta AR Pant was not warm enough. We appreciate your feedback and will pass this along to our design team for review. The Beta AR Pant was designed to be a highly versatile GORE-TEX PRO pant delivering durable, breathable weather protection that you can wear overtop of your midlayer. The pant does not contain any material that will provide warmth, we always recommend layering up underneath for an added layer of insulation.
Great pant but room for improvement.
I really like these pants, they are comfy, provide great wind and rain protection, the zipper on the bottom is nice for larger boots. Couple things I would like to see in these pants is a hook on the draw string down on the bottom of the boot. I wore these the other day in quite deep snow and when I fell through the draw string wasn't enough to hold the inside lining down and ended up getting snow in the top of my boot. Also wouldn't hurt to have an extra pocket or two. Great pant but room for improvement.
I’d hoped for better
I bought these to replace my old winter climbing over trousers but unfortunately had to return. I found the fit very awkward, size medium the waist fit well but was very tight over the upper thigh and the large was too baggy at the waist and the thigh. The trousers came with thigh vents but unfortunately no full length side zips. I wasn’t able to put these on/take off over a pair of alpine/ice climbing boots. The trousers include attachment points for suspenders but these are not included.

Poor Fit
I love the features of this pant but had to return because they didn't fit properly. I ordered a size medium regular (I typically wear a medium in everything) but there was a ridiculous amount of extra material between the knee and ankle while the waist fit perfectly. Especially disappointing because size medium short is out of stock and unavailable to order in the tatsu color. I would love to order these but cannot. Hope they are back in stock before I begin hiking this spring.
Hi Randy. Thanks for sharing your feedback on the Beta AR Pant. We are sorry to hear that you are disappointed with the fit and the they were too long. We appreciate your detailed comments and we will make sure to pass them to our team.
Lack fast put on option.
Really nice pants, but I returned the pants because they are not capable to be put on with boots. I'm looking for a model like the Beta (short inseam) with the full zip on each leg to be able to make quick change of cloth in case of rain, but with a really tough Goretex pro tissu like the Alpha SV. I'm also disappointed that Arcteryx don't offer a short inseam option for all their pants model. I'm hesitant to buy the Beta pants because I'm not sure they are touch enough for my need.
Good after some weeks in use
I've not had these on for too many times for the review, but here goes; overall, I was pleased how high the waist comes up - I am using these for skiing and general outdoor activities in winter and I was afraid that snow gets in. That hasn't been a problem so far. The waist does get a little tight here and there, though. The legs also open enough over ski boots, so all in all, these are pretty nice.
Solid gortex but little long
A lot of reviews below me people were not stoked with the pants. My biggest crutch with them is there are no pockets. I had to return them because they were too long and I ordered 34 R at 6 feet 190 I figured that would be fine. Overall the pants are nice, great material and they will definitely keep you dry. Just didn’t like the no pockets (I should have known this prior so no fault to Arc’teryx.
Just Great!
Everything feels top-notch on these pants! Bought them to keep me dry on long backcountry hunting trips and alpine pursuits, excels at both. The thigh pocket is a great feature (fits a phone/map and compas). The fit makes it easy to move. Wear long socks, the instep guard can rub on your shins in low-top boots :)
