I think it's worth noting that the drawstring waist adjustment is different from "traditional" designs. The design makes sense, but tightening is a bit counter-intuitive. Most drawstring designs that I'm familiar with encircle the waist circumference and emerge from within the fabric "waist tunnel" before crossing the center of the waist. Tightening such a traditional design is most effective by continuing to pull along the length of the drawstring as it crosses the waist. With these pants, however, zippers at the sides require the drawstring to be anchored at the left and right (and not continue behind the back). Additionally, Arcteryx's approach has the left and right drawstrings cross past center *before* emerging from the fabric "waist tunnel" -- so the ... MoreI think it's worth noting that the drawstring waist adjustment is different from "traditional" designs.

Tightening is best accomplished by pulling the drawstring emerging at right to the right, and similarly pulling the drawstring at left to the left.

East Coast Canadian weather has come with minimal snow and lots of cold rain. I was looking for a lighter (hiking) version of my faithful ski guide bib pants. Something with a full zip and easy to get into and out of. Was looking for waterproof, windproof and comfortable - product delivered. Fit was as expected from previous purchases. Will be using for attempt at Kilimanjaro in March. Layering will be key to go from rain forest to high Alpine.

To be fair, I did reach out to customer service to explain the issue and give them the opportunity to address my concerns with this product. Their response: write a review. So here goes. I purchased the beta LT pant 3 months ago. At first I was excited to have them. They were intended to complete my 2022/23 winter needs as I had already purchased the alpha sv jacket. However, upon putting the pants together with the 2 side snaps I was completely shocked at the poor design of the pant. Please keep in mind that these are $380 pants! After securing the snaps one must bend over to put on one’s shoes. The snaps came undone. When I went to access my base layer pocket, the snaps came undone. When I attempted to use the front fly, the snaps came undone.

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 ... MoreArc'teryx has the best form-fitting outdoor wear in the market - guaranteed!

Overall, highly recommend these incredibly versatile, form-fitting rain pants. They're absolutely worth it. You won't regret it!
I bought these specifically for hiking in snow. I opted for the Men's Beta Pant because of price. The Women's Beta LT Hadron Pant was more expensive and I wanted a less expensive option. These worked out perfectly for my needs. Great fit (I have curves), comfortable and will probably last my lifetime. I wore over my base layer bottoms and just felt like I was wearing normal pants all day. Didn't experience that crunchy feeling with other hardshell pants I've had in the past.
Gore-tex, fine, fit is real, looks nice. However, major problem is that there is no way to tighten pants! There are two cords which are supposed to help but impossible to tighten them up. Useless design. Has someone tested this before production? Great pants, if they fit you perfectly, that you don't need additional adjustment. And, yes I know there will be minuses and dozens of positive reviews after this. Whatever.
I haven't had a chance to use these yet, but wanted to leave this here in case this is helpful for others (tl;dr: try 'em on if you can. Sizing is not straightforward and your use-case matters):I live in an area where I don't have the opportunity to try these on at a retail location, so went through several attempts to get the sizing right. For reference - I wear a size medium in regular length (32" inseam) in *almost everything*, including all other arcteryx pants that I own. I'm 43, 5' 10" (178cm), and typically somewhere between 165 and 170 lbs (75-77kg) with a middle aged athletic build - no six-pack here, but I'm no slouch either. My actual waist measurement is around 35" (89cm) at the time of this review, which puts me on the upper end of Medium in the ... MoreI haven't had a chance to use these yet, but wanted to leave this here in case this is helpful for others (tl;dr: try 'em on if you can.

My actual waist measurement is around 35" (89cm) at the time of this review, which puts me on the upper end of Medium in the sizing chart, but still a couple inches short of the Large. My use case is that these will primarily be layered over a light to mid-weight softshell pant in cold & wet conditions. (Typically a pair of gamma lt pants or similar pieces from other brands, which fit comfortably in a size M, regular length.)I tried size Medium/Regular (too long and not enough room to layer underneath), Large/Regular (just too long), and I finally settled on the Large/Short inseam. I do have to cinch the drawstring a bit, but not an excessive amount. This also gives me a bit of a buffer for bulkier/additional layers underneath if needed. (The drawstring *does* work, pull them away from each other as noted in another review here somewhere....). These also seem to be sized longer than I'd expect - with the regular length being absurdly long for me, even with boots on. I was nervous that the short inseam would be too short, but it turns out to be just about perfect. For me, the Medium would have worked over a light baselayer, but for the way I want to use these, I wasn't confident the Medium would work. YMMV.The sizing is a bit weird, and I don't love the snap closure at the waist, but after lots of research these were the best option for a relatively lightweight, full zip, 3 layer gore-tex pant. Fingers crossed that the bit of extra room in the waist also prevents some of the issues with the snaps coming un-done that others have commented on. (Haven't experienced this yet, but as I said above, they also haven't left the house....)
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 ... MoreI 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.

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
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 ... MoreIt 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’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.
I purchased this product 6 months ago, and have been wearing it while hunting in the bush, as well as hiking in BC, and Ski Touring. They are a wonderful pant, that provide excellent waterproofing, and are super durable. However, I do have a gripe with the design. I am forced to wear suspenders with the pant, because there are no belt loops on the pant, nor is the fabric tighteners on the front of the pant very effective. If I go belt less, I have to tuck thicker layers into my pant, and it makes it difficult to regulate temperature. I know that the pants are made more for an alpine environment, but I would love some more utility out of the pant.
