Arc'teryx has the best form-fitting outdoor wear in the market - guaranteed! And sure enough, these Beta pants fit very well (I'm generally a 31x32 and went with size Small as the Medium was far too big). I use them primarily for my biking commute on the southern Oregon coast where we get lots and lots of HEAVY sideways rain. These pants, along with my Beta LT jacket, keep me bone dry throughout my 3-mile bike commute. Contrary to what others shared about the side zippers being a nuisance to operate and being somewhat of a discomfort in heavy movement, I think they're easy to use and don't feel them at all during my bike ride. The crotch zipper is nice, theoretically speaking, though I think the opening could be a bit bigger. The only suggestion I have for future models is to incorporate zip side pockets and a rear pocket. Overall, highly recommend these incredibly versatile, form-fitting rain pants. They're absolutely worth it. You won't regret it!

I got these pants to use for a backpacking trip in Kananaskis this past weekend as the forecast threatened a decent amount of rain and potential thunderstorms, so I figured it would be the perfect opportunity to upgrade from my GTX Gaiters. Overall I was quite pleased with the comfort that these pants provided while doing basic camp chores in the rain. (Setting up the tent, Cooking dinner, hanging a bear bag etc.) I also found these pants to be perfect for the trek back to the car as the rain had stopped but the brush along the single track trail was soaking wet. My partner who was wearing the gamma LT soft shell pant ended up getting soaked in the legs from this brush while I was nice and dry. I found the GTX C-knit backer to be perfect for this pant as they did not feel clammy even after 5 hrs of constant elevation gain. When I have used GTX pants in the past the clammy effect has always been present and I find that quite annoying . These pants are packable enough that I can comfortably fit them into the rolled up hood of my Beta LT Hadron Jacket, which makes the pack organization freak in me super stoked. I have two gripes with this pant hence the 3 star rating, they are the following; 1. The pants do not feature a lace hook that could attach to my boot. My Beta SV Bib pants feature this lace hook and it does an excellent job at sealing out snow, water, dirt and other debris one might come across while frolicking in the backcountry. 2. For some reason the top zipper is very difficult to unzip, it definitely does not come down on its own which is nice but it seems to be extra challenging to work with. At the end of the day if you are looking for a fairly lightweight, fairly durable and fairly breathable waterproof, wind proof pant this is a pretty good option. I would personally recommend this pant to any friend who intended to use it for hiking, biking, and maybe even some climbing too. If a future model solved the two problems I have above this pant would hands be a 5 star piece of kit. Happy Trails

I just got these pants along with the Beta AR Jacket and Atom LT Hoody. Everything is amazing quality and fits better than any other brand I've worn. That being said, the black Beta pants don't perfectly match the black Beta jacket. The pants have a slight blue tint and are a bit lighter than the jacket in the same color. This is obviously not a big problem but I wish they were the same tone of black. I'm sure that this could be a dealbreaker for some OCD people. Anyways, the pants are VERY waterproof and have nice zippers going down the entire side of the leg for venting or easy access to layers underneath.

It pains me to say this because I love every piece of arc gear that I have but these are not great they are not up to the quality I expect. The quality of the zippers is quite surprising actually. I was very excited to get these pants and try them on, I struggled with the zipper on each side for over two minutes. They were very very hard to get a part and get started, these zippers do not feel nice. I finally get the pants on and noticed two things, there is no button on the front for the fly and the drawstring to tight in the waste is really really bad. The drawstring has a strip of grip running down it which makes it really difficult to untie. This is not nice adjuster that is in my Zeta Pants. I've tried these pants on numerous times try to convince myself they are ok. It's a struggle to get these pants on and off. There is no getting in and out of these pants quickly. The pants are always falling down slightly because I don't want to tie the drawstring too tight. The Zipper on the right hip didn't seem to want to close all the way and stays a little open at the top unless you really pull on it. Unfortunately when I try this on with a pack both top zippers sit right under my hip belt. I really wanted to like these pants but these are a huge disappointment. I don't say this lightly as I'm a huge arc fan but I wanted to let people know as there were no reviews when I order mine.

THE PANTS ARE NOT FULL ZIP AS PICTURED. I was trying to order the previous season beta pant but these are the new ones with 3/4 zip. The new design looks and feels cheap and is missing some of the essential features such as full zip… The Arcteryx brand is going down the drain.

I love the gore tex pants , but their isn't enough shorter lengths available in most versions , Arc'teryx needs to address this problem and also need to increase production with the existing offerings with shorter length offerings. I'd also would like to see an option with a tighter ankle cuff for non boot activities.
