A workhorse in alpine playgrounds.

Arc'teryx designed the Beta Men's Beta AR Jacket as a backcountry workhorse for alpinists who like to take a beating from the elements without sacrificing performance. This jacket features a Gore-Tex Pro Shell three-layer construction with Arc'teryx's tightly-woven N40p-X shell fabric that includes a DWR treatment to slough off rainfall while you romp up 14ers or get caught in a snowstorm at the top. The Beta AR is reinforced in prone-to-wear areas, like the shoulders and arms, with N80p-X nylon so it will handle pack straps and ice encounters season after season.

Fully taped low-bulk seams and WaterTight zippers will block out any moisture you encounter. When it starts puking, take shelter under the helmet-compatible DropHood with its draft-blocking separate collar, and stuff your hands in the two hand pockets, which are placed high so they play well with hip-belts and harnesses. Underarm zip vents let you cool off without sacrificing any protection from the weather. The storm will pass (it always does) and you will reign supreme on the mountain top.

  • An all-around shell for hiking, climbing, and spring skiing
  • Waterproof and breathable Gore-Tex Pro shell
  • Fully taped seams with low-bulk microseam allowances
  • N80p-X and N40p-X shell fabrics are lightweight and durable
  • WaterTight zippers prevent moisture from getting through
  • Helmet-compatible hood with separate high collar and laminated visor
  • High hand pockets and 1 internal laminated pocket
  • Trim fit with no-lift gusseted underarms and articulated elbows
  • Item #ARC3653

Beta AR in St Anton

Easy for my son to follow me with this bright jacket.. Note even with a pack on pockets are still accessible. Short cut waist works for me, skiing with bib pants, would easily fit a harness too.

What is the real difference between this Jacket and the Theta AR? I've compared the specs, but they seem so similar that any difference feels negligible. Could someone explain?

Best Answer

Hi Sahil, the main difference is that the theta is a little longer and has an additional sleeve pocket but yes, they are very similar. The Theta tends to be the preferable jacket for climbers as they usually like a longer jacket that wont ride up from the harness.

Let me know if I can be of further assistance!

Brittni nailed it.

Here are the differences in length:

Theta AR Jacket, center back length: 32in/81cm

Beta AR Jacket, center back length: 29in/735cm

If you're looking for a climbing jacket checkout the Alpha jackets (SV, AR, FL)

I'm looking for a good all around waterproof shell for wet ski days and also rainy hikes, etc in warmer weather. Contemplating Arcteryx AR, Procline, and Stingray. Suggestions? Other comparable brands/models in the same price range or less to consider, as well? Waterproof and warmer weather versatility are key. Thanks

Beta AR is a great jacket, but the length may not cover your hips. Good if you ski /tour with say a bib snow pant, like I do, or need to wear a climbing harness. With a pack on, it cinches tight for me around the waist. Sleeves are long for reaching, and the minimal design (no powder waist, or extra pockets ) means it packs small. The Goretex fabric is very tough. Hood is great, covers a ski helmet for those cold chair rides. I am wearing it in my insert pic here.

I like this jacket so much I have 3 of them!

Best Answer

Of the three jackets you listed, the Beta AR would be your best bet. The Stingray is geared more toward resort skiing and the Procline is a nice composite piece but to really seal out the wet, the Beta AR is tough to beat. If you are looking at other brands, give the Patagonia Refugitive Jacket a look.

If I can buy an Atcteryx Beta LT Hybrid at REI on sale for $250 is it worth the extra $107 for a Beta AR on sale at Backcountry for $357? Why? Thanks.

The short answer is: it depends. It depends on what you plan on using the jacket for and how hard on it you plan to be. The LT Hybrid uses 40-denier fabric 3L Tricoc & Paclite Gore-Tex, whereas the Beta AR uses 40-denier & 80-denier fabric with Pro shell Gore-Tex. The AR will be burlier and able to take more abuse. Pro shell is supposed to be the most breathable, durable, waterproof available. If you're not wearing a pack much, brushing up against rock or brush, the LT Hybrid might be the better choice. For an extra 107, I'd get the AR...just my opinion...


Will this jacket work well in the Sierra Nevada, Yosemite National Park area? Looking for something to use in our high country and rain season. Mostly for long day hikes and backpacking trips.


Thanks for the question! You could definitely use this jacket in that region. Depending on the time of year, you'll want to tweak your insulating layers.

Is just a shell or is there any insulation. Im going to tropical area where it rains randomly so no insulation needed.

Best Answer


This is a great jacket but if you're heading to a tropical location, you might want to consider a jacket that has Gore-Tex Active instead of the Gore-Tex Pro. Pro is great and durable but the Active will breath better an that is what you'll want for tropical locations.

I'm 5'5'' and 140 lbs, I currently have the Small in this, thinking about returning it for an XS. The arms are too long and the chest a little bit big but the fit is good everywhere else, . Will I be happier with an XS or should I keep the S?

Hey Ky,

Height and weight aren't going to be the best measurements for jacket sizing. Chest measurement, torso length, and sleeve length are going to be better indicators. That being said, The XS is going to be 2 inches smaller in the chest and one inch shorter in the sleeve length. If you would like to further discuss this jacket or others, give me a call at 1-800-409-4502 ext 4446 or email at

Hello, I am 5'9" and weigh 163. Do you think I need a large if I am going to layer with a midweight Merino baselayer? Looking at the Beta AR

Best Answer

Late answer but this may help others looking at sizing. I am 5'10", 165, 32" waist and 42" chest. My shoulders are also a little bit more beefy than say a runner or other cario-oriented person's. Every Arc'Teryx piece I've tried on is tight around the armpit area in size medium. Large always fits fairly well, with a bit more arm length than I want (32-34 dress shirt arm length). With the newer fit system they use, the large still hugs my body closely enough to be functional, and not look too wide. Hope this helps those who are gym goers as well as outdoor enthusiasts.

I am interested in a Beta AR jacket and am curious about if there is a difference between the outlet version and the full price one?

Best Answer

This year they are using a new version of Pro shell which is more durable and more breathable (they got rid of the oil barrier layer and made a sort of sandwich construction of the ePTFE membrane). It should be 22% more breathable according to Gore.

Typically there really isn't much different between the full priced models and the outlet products other than color since that's about all that changes from model years. However, in this case Gore-Tex has actually updated their Pro-Shell and made it 22% more breathable while still making it more durable. So in this case the current full price model will have that difference over the past season models, and that is why we gave it a new item number, instead of keeping all model years on the same product page and just change the price for the specific options.

Im just under 5'10" with approx a 41" chest and weight 178 lbs. What would be the best fit to layer either a atom lt or montbell alpine light? also has the fit changed from last years model?

Best Answer

Fit is the same and has a generous amount of room for the dimensions Arc'Teryx states. I bought a Medium and a Large in their "athletic fit" Beta AR. My dimensions : 5'10 185 lbs. 42 -chest; 33 -arms; 34 -waist; 16.5 -neck . The Large was huge in the chest and arms and could fit a full 800 fill down coat under it. I returned the Large and kept the Medium which I think fits way better in the arms and chest. However, the Medium is slightly constricting when you put big layers under it, so I think the Large would give you the guaranteed room and movement you might want with those coats underneath.

What has changed for 2013, other than the price?

The Gore-Tex material has changed. Not sure exactly whats different but I know that now its called the N80p-X and N40p-X shell fabric where-as before it was called something different. It's also 2.3oz lighter than the previous model which I think probably comes from the new material. The new Gore-Tex Pro which touts a 28% improvement in "breathability", improved ruggedness, and more durable water and windproofness than last years Pro Shell product. There might be more changes but those are the ones I'm thinking changed the price. Hope this helped.

Best Answer

In the 2013 Beta AR Jacket, the material crosses over to GORE-TEX's new N80p-x Pro Shell. Same material used in the Alpha SV and and Alpha LT, whilst serving a greater purpose of being an all around jacket. Hope this has helped.

I had the alpha SV with the new face fabric. It's much quieter than the older fabric they used. Also if you look close the older material has these little squares all over and can catch on tree branches and all. The new stuff is snag resistant. It's very smooth. That said I went with the older beta AR
