Great Rain Pants
These are great rain pants. In the hard rain they keep you dry. I gave them a 4 and not a 5 for a couple of reasons. First I find that they tend to be bit baggy around the knees or just under. In previous rain pants if they were baggy it would be around the ankles. This just looks weird. I wish they had put pockets on the pants. There is a thigh pocket but if you put something in there it tends to fall against the top of your knee. I'd rather have traditional hip pockets. I prefer to put my phone or other stuff in there versus putting it in my jacket pockets. The pants are well made, but as with some rain gear tends to be a little loud when you are walking
Not waterproof
I was using these pants on a light hike on the mountain. Was not raining and the water went trough to my inner pant. It was wt outside, but i think a pant with this price an "quality" didn't live up to the expectations.
Easy to put on, but missing key feature
The pant functions well, there isn't any restrictions in my mobility with the pant over any hiking pants and the length of the side zippers makes it easy to put on while wearing hiking shoes. The durability has held up over a pretty wet summer of backpacking, generally the pants just get shoved into a remaining spot in my pack as there isn't a pocket that you can self-pack the pants into. The pants do fit into it's own leg pocket as an improvised method, but since the zipper is one-way it's not a great solution.
Surprisingly large number of design flaws.
I bought these pants and returned them after 3 days mountaineering in Cordillera Blanca, Peru and 1 day of use climbing Mt. Kilimanjaro. I would have returned them after Peru but didn't have time to get new pants for Kilimanjaro. Main issues: (1) the fly zipper tab is super short and unable to be used with gloves on. You can zip down, but then tab gets lost in the fly folds and you can't grab onto it without gloves on. Don't buy these pants if you need to visit a tree in the cold (2) Pants are very baggy. (3) the plastic belt buckle fell off when I took pants off and almost got lost in the snow. (4) they're super loud with any movement. I've had good experiences with Arc Teryx before, so pretty surprised there were so many design flaws. I do like the full zipper sides but that was the only thing I liked about them.
Awesome Weather Wear
I'd been eyeing these pants for some time and, after extensive research into what the very best waterproof hard shell pants would be, kept returning to the Beta pants. Now that I have them I'm thoroughly satisfied. Extremely light weight, they pack incredibly small. Love the side zips allowing the ability to get these on quickly when the weather turns without removing footwear while also providing substantial heat dumping as needed and maintaining a high degree of breathability. The material feels incredibly durable. These pants tick all the boxes. I'm looking forward to using these for the next several years.
Decent pants with some room for improvement
This is for revised version 2024/2025 Fit: Not slim fit like before. True to size with articulated space around knees, which looks a bit bulky. You can probably even fit some knee pads with 1 or 2 layers in them Fabric: PFAS free GoreTex with higher denier than previous, which is more durable but also a bit more stiff and even more noisy (cracking sound) during movement 3/4 side zip instead of full zip - I'm ok with either but some might have strong opinions. No more elastic band (was criticized for being useless). No hanging loop. Surprisingly how much I miss hooking pants so easily with it
Excellent pants
Truly happy with these pants! I’m 5’10” and weight about 140lbs, grabbed the medium size with regular length. They do fit a little big which is great for layering. The adjustable band around the waist as well as the leg pocket are my favorite features. Although they aren’t really made for skiing, they still preformed very well, just had to pull the zipper up around boots.
I used this for skiing
Great wind proofing, but also breathable never to hot or to cold as long as I stay active. Since I us this in the winter time I don't usually use the water proof feature but it does come in use occasionally. I know the application of these pants aren't centered around skiing/snowboard so the fit isn't the greatest around the boot area but otherwise they fit amazing. I haven't used them all to much only a couple times but it seems quite durable to me I haven't had any problems. So yes I would recommend this product to others.
beware, I’ve been bitten TWICE
I know that you feel that your buying the best, or maybe think that you will look cool in all Arc’teryx - I did! I’ve had their jackets and pants AND TWO OF THE THREE HAVE HAD SEAMS THAT FAIL AFTER 3-5 YEARS. You pay a premium but I warn you, the performance isn’t worth the price.
Too Baggy
I switched to these from my Norvan shell pants. I prefer the more durable fabric of these, but they are very baggy and very noisy--not very stylish! The ankle cuffs come loose all the time, and the cord hangs out awkwardly. I preferred the Norvan, which had the pant leg taper towards the ankle, and then you would just close the zipper to secure it. I can see why the ankle cuff is adjustable, however--these are clearly meant to be worn over ski boots (and a bunch of layers).
