    Solid But Not So Breathable

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: Medium

    Everything about the style and fit of the Beta SL is perfect. No complaints there whatsoever. The DWR works super well and I have used it under heavy rain at least a dozen times with no problems. However, the Beta SL is hardly breathable at all. I usually layer it with the Atom LT during outings and when I'm working hard on an uphill section or jogging you almost feel that you have a garbage bag over your head instead of a performance jacket. When I stop there is literally steam coming out from under my hood. That being said, this jacket is made almost exclusively for emergency weather protection, not sustained active use. But beware, if you're looking for a cheaper alternative to some of Arc'teryx's spendier shells breathability should not be at the top of your list.

    Great for ski mountaineering

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: L

    I used this jacket as my shell for ski mountaineering last season. I love having an extremely light weight and very packable shell. My previous shell had arm pit zips, but I found that I didn't make much use of jacket was either zipped up or off. Thus, I really don't mind that this jacket doesn't have the pit zips.

    I haven't used it enough to be able to comment on its durability (something I wonder about), but I did get a great season out of it without any problems. I expect and hope it will hold up for a few more seasons, but even if it doesn't, I would still be happy with it due to the light weight, packability, and performance. I say this because a failed mission could potentially cost me more money in travel expenses than what I paid for the jacket, and light weight, high performing gear, can significantly increase the chances of success in mountaineering.

    Great for exploring waterfalls

    Love this jacket. Stayed perfectly dry going behind waterfalls in Iceland. Also worked well on a day hike while it was pouring down rain. It's light and durable. Held up great on a month long backpacking trip through Europe, being packed in and out and thrown around. Definitely worth the money

    Great for exploring waterfalls

    Simple Form + High Function = Beta SL

    • Familiarity: I've used it several times
    • Fit: True to size

    My Specs: 165lbs, 6'-0", 32w, 32l, long arms, broad shoulders/chest

    Applications: "Emergency" rain shell for trail running, biking, paddling, and casual use between late fall to early spring in a temperate mountain environment. Layer-ability ranges from a base layer, R1, and Nano Puff.


    +Fits my frame and long arms very well. Went with a Medium.

    +Packability and weight are competitive with others in its class. I can easily roll this into the hood, and it fits well in my running vest or pack

    +No pit zips. For me this is a plus. I prefer a parred down jacket. If you want/need pit zips, get a jacket with pit zips.

    + Waterproof zipper is super easy and glides effortlessly with one hand.

    + Hook-and-loop cuffs and hem drawcord work great and are much appreciated when the weather calls for them.

    +Good color options. I went with the Masago for visibility while on the bike or walking/running in the woods during hunting season in the mountains. Humored that the color is named after fish eggs, too.

    - Hood is a bit oversized. This is described as a streamlined hiker/backpacker jacket. Is a helmet compatible hood really necessary?

    - Price is steep, but I plan on having this for a very long time.

    Summary: A very lightweight, functional, streamlined and attractive jacket. For its intended "emergency" use, its fantastic. If you can get over the price, its very worth it.

    ya get what ya pay for

    I've taken this jacket to hell and times and it begs for more! To say I've taken this thing through the wringer is an understatement. With that being said I've washed it with Nikwax a couple times and that is a small price to pay for an amazingly warm simple jacket. Wouldn't trade this bad boy for the world! I highly recommend it and any other Arc'teryx gear..if you can afford it!

    ya get what ya pay for

    Love this jacket

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I've had this jacket for several months now, and feel like I can finally offer a review of it. I own this and the Alpha SL Hybrid, which I believe has been discontinued, but I'll compare it anyways.

    First, I have both jackets in size medium. I'm about 5'10" 165, they fit me with a little bit of room to layer, but still fit well and look good just over a t shirt. The fit is almost identical, the Alpha SL might be just a tad roomier, but not enough to notice.

    Both are incredibly waterproof and windproof, no problems there, and the feel of the fabric is great. For some reason I feel like the Alpha fabric is a bit tougher and the Beta a bit softer, but it could be just the color, in my head, or who knows. Both feel bombproof.

    There are a few things I really love about the Beta over the Alpha:

    --The hood--it's not massive for a helmet, which I rarely use with this jacket, and fits SO much better on my dome.

    --Pockets--on the Alpha, the pockets are a bit too high, they make walking with your hands in them crappy. Beta placement is good, out of the way of a hip belt or harness, and still good for hands in pockets.

    What I like about the Alpha over the Beta:

    --PIT ZIPS! why are they not on the Beta?

    --Vislon zipper rules. Doesn't snag, feels so much nicer.

    Overall, if I had to choose one, I'd probably go with the Alpha hybrid, because of the zipper and pit zips. But it's nice to have both for different reasons. I'm sure during summer Atlanta rainstorms, the Alpha SL will win (pit zips!), or if I wear one climbing or anything with a helmet. The Beta is more of a throw-it-on-over-a-hoodie-for-wind-and-rain-protection piece for me, and it excels.

    The soapstone color is amazing. It's a great dark great, goes with everything.

    I am a tower technician so getting something that keeps me dry is crucial. I've put this to the limits with its first test being in Juneau, solid rain for a week straight and this thing kept me dry 150 ft in the air with no protection from the elements except a tower dripping even more water on me. Next test was Dillingham, where it was blowing 30-40 and raining for 4 days straight, again, it kept me dry except for those few spots around the neck/wrists where it wasn't completely sealed. Regardless, with proper layering and common sense, this thing will keep you dry. On top of being completely awesome as far as water resistance, I've have a few sketchy brushes against corners of angle iron and sharp pieces of metal, the outer layer has stayed strong and true and hasn't had one rip. The inner layer does seem a bit more delicate and has had some minor wear marks but still keeps me dry. After 4 months of wearing this I love it and have brought it with me and will continue to bring it with me on every trip I go on.

    Edit: Forgot to add I'm 6' 165lb and the large fits perfect, I have longer than average arms but it fits great and still leaves room for a sweatshirt/layers underneath. Drawcords make everything sit where it should.

    Pricey but very compact and practical

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I had used the Beta SL Jacket for over 2 years and I had great moments and bad experience. It is very very small and compact so great for traveling, backpacks and very light. I love the fitting and the color looks good. I had the Patagonia and does not like the fitting. I paid high price for this so I used it all winter and keep me dry. I had couple of bad experience where it soak during heavy rain. I had to apply rain proof wash again to make sure that it is water proof and it works like magic again. Does not keep you warm since you need to layer with a fleece but block wind very well. I would recommend it but the price is just too expensive for rain jacket.

    Almost perfect.

    • Familiarity: I've used it several times
    • Fit: True to size

    I have been a patagonia diehard for decades, but their totally inconsistent sizing has finally done me in. Started looking at the arc jackets - looking for lightweight raingear for hiking, etc. led me to this. I also got the corresponding pants. There's a patagonia jacket, the M10, that is 2/3's the weight. Doesn't have pockets, though, and an XS was big on my 6'2 170 friend. REALLY? Fit on this jacket is better for me, but at 5'8, 130lbs, I probably need a (nonexistent) XS. Sleeve length and arm fit is ok with a puffy on underneath, but otherwise it's a little baggy. Ideally, this would come in an XS, and have 20% lighter fabric. Otherwise, the collar, hood closure/adjustments, pockets, and details make it absolutely fantastic.

    I think I got a lemon

      I used this jacket two times under heavy rain. I ended up soaking wet both times and my cellphone died inside one of the pockets.

      I love Arc'teryx and hopefully this is just a manufacturing mistake. I just bought the Alpha LT to replace this jacket.

      You did not get a lemon. Paclite tends to wet out quickly and eventually soak through. Arcteryx also does not recomend you carry your cell phone in the outside pockets during rain as the zippers are consiered watertight (not waterproof). The alpha LT will solve this isse since it has an inside pocket

      The jacket isn't leaking (apart from the water resistant zippers). The jacket is wetting out. Solution? Apply another DWR coating in your dryer. What you are experiencing is internal condensation from your own sweat. Paul above mentions 'soaking through' after wetting out. This is not possible.

      Great Lightweight Shell

        This shell is great as long as you dont pretend it is something that it is not. This is a great layer to throw in your bag in case it might rain or to use if you want to go super light-weight but without stressing about getting caught out in the rain. It weighs almost nothing, packs down super small, looks stylish, and is waterproof/breathable enough to make it a few days in the rain.

        This is not a long term expedition shell. It is noticeably less waterproof and breathable than a Gore-Tex pro shell, less durable too. It doesn't have pit zips, and I would usually get a little wet in a downpour. I wouldn't take it skiing in the trees either.

        All in all, it's great, it just isn't a great coat if you plan/expect on being out in the rain for days at a time while exercising. I've had mine for a few years, it mostly lives in the bottom of my day-pack, but when I get caught in the rain, it does just fine till I get home.

        everything is good but its not w/proof

        • Familiarity: I've used it several times
        • Fit: True to size

        got it on sale at other store prices for these i see dropping like crazy ive got it couple months back but havent notices that its not 3 layer but still it says ''garanteed waterproof''....

        anyways had it 3 or 4 times under somewhat heavy rain, inside the hood had drops of water , shoulders also got wet even though i was outside for 5 min max .

        returned it first chance i had.

        Gotta love this jacket

        • Familiarity: I've put it through the wringer

        This is my first Arcteryx jacket and I gotta say I might be fully converted. Just from picking it up and putting it o you can tell its made with excellent craftsmanship and materials. Being from Oregon I know how being in the rain every day for 4 months feels. Its great to have a go to rain jacket that can also be used for so much more> I have used it for hiking, fishing, and even duck hunting(threw a camo shirt over the top of it and I stayed dry all day long.) I like the storm hood and its versatility. Great overall jacket.

        what is the difference between alpha SL and Beta SL? Thank you!!

        Best Answer

        The Beta SL is designed for hiking and trekking while the Alpha SL is designed as a compact, lightweight emergency storm shell.

        Main differences will be the fit and the pocket configuration. The Beta SL features an Athletic fit while the Alpha SL features a Trim fit. The Alpha SL is trimmer in fit and lighter in weight. The Alpha SL has one chest pocket while the Beta SL has two hand pockets.

        I hope this helps!

        Hi currently i use the Gamma LT Jacket in size M, however i would like to use the Beta SL as the final piece in layering with a base layer as well as a fleece, would it be better to purchase the Beta SL in size L to accommodate the extra layers?

        What is the center back length of a medium?

        I'm just curious how this would fit with...

        I'm just curious how this would fit with the Atom LT Hoody. I'm trying to save some money, so I was looking at the Beta SL. I know the Alpha LT would be the best shell to combine it with, but its a little too pricey. Considering how the Beta SL is part of the Beta line, is the drop hem going to be long enough to fully cover the hem of the Atom? If not, I might just wait to save up for the Fall '12 Black Alpha LT.
