What’s next from Arc’teryx? A jacket so supple you have to pour it on?

At this point, we’d have thought Arc’teryx couldn’t find yet another way to improve on the Men’s Theta AR—this alpine shell already has so much going for it, from its Gore-Tex Pro material and ultra-thin seam tape to its helmet-compatible hood and high hand pockets that you can get to while wearing a harness. But Arc’teryx did make a slight change for the better: This season’s Gore-Tex Pro Shell fabric is just as waterproof, breathable, and durable … plus it feels suppler and more pliant, so it moves with you even better than before. Open up the Theta AR’s waterproof underarm zippers to stay cool as you break trail for the final summit push, and then seal them tight for your ski descent through fluffy powder—the jacket’s long length helps to stop spindrift from getting underneath this bomber shell.

This Is It

If you could only own one shell this would be the one. The Gore-Tex Pro Shell is a barrier to mother nature. it can handle downpours, gusty winds and yet breathe to keep you from sweating. I have had my jacket about 6 months and it has been very durable so far. The fabric is slightly stiff when you first get it but will soften with use. The pitzips are a great feature.

The Best

Having owned this jacket for almost a year I can honestly say it is the best jacket I have ever owned. I felt kind of silly paying this much for a jacket, but it has been money well spent. I am a Boy Scout leader and we are out camping/hiking every couple of weeks. Even in the worst midwest thunderstorms I have been dry as a bone. I know it's a lot of money, but I feel it's a worthy investment. I feel so strongly about the quality that I just ordered the rain pants to go with the coat.

What do you think it feels like????

I'm going to quote Jeremy Clarkson from Top Gear talking about the Aston Martin DBS V12..."Its an Aston Martin. With a V12. What do you THINK it feels like???"

Well, this is the Aston Martin of storm shells. The hood is outstanding both with or without a helmet on, the pulls adjust pretty much perfectly, the sleeves have awesome motion, and weather has a snowball's chance in hell of bothering inside this jacket.

Minor, MINOR gripes:
-I wish there was some way to stow the hood. Its pretty much there all the time.
-Gore Tex Pro Shell can get clammy on the inside if you're working hard and its really cold outside. Good layering will mitigate this.
-The DWR coating has pretty much given up on my jacket. I'm going to try refreshing it in the wash with some Granger's tomorrow and see how that does.
-Fit was perfect for me, but that pretty much guarantees that it will be wonky compared to other Arcteryx gear (which doesn't fit me). Make sure to try this out somewhere before committing.

Tank Shell

I like everyone loves Arc Jackets. This I think is the best mountianeering jacket on the market today. I would like to note that they are big mountian jackets and if you dont enter the relm of the super cold then you should size down. I have a large and it fits like a extra large no joke. Get your size if you plan to layer like no other. Your results my varry but, I also have the older XCR model and it seems to be holding up way better than this new proshell.. I'm starting to wonder if they focusing so much on making it light weight that they are over looking durability. Light contact with rocks and I already have a few holes.. Proshell is a type of gore-tex fabric so I guess I can't blame Arc too much but, still..

You may try contacting both Arcteryx and Gore Tex and see if they'll replace your shell for you, regardless of the abuse that has been shelled out. This is like the Mercedes of outerwear bought at Nordstrom's and their customer support matches that- I had my Theta AR get bound up in my harness and it kinda chafed the Gore Tex and totally ruined the DWR in that area and they replaced it right away.

Using the theta as an outer shell with just an icebreaker merino underneath served well during a sunny winter day in NZ

Hi gurus! between this one and the theta sl,which would be better,durable,comfortable,nicer look and warm? thanks!

Both jackets are going to be fairly durable considering their construction and intended use. The Theta AR is a little heavier so it would probably edge ahead of the Theta SL in durability though.

Comfortable and good looking are more for you to decide. I've worn a few Arc'teryx jackets over the years and I think they have all been good jackets to wear and they definitely always look nice.

I'd recommend going with what your primary activities are.

The Theta SL is their super light version. If you are a backpacker, doing some hiking, or just casual urban use this would probably be a good way to go.

The Theta AR is an all around jacket more designed for mountain activities like climbing, mountaineering and such. It is a bit heavier than the SL so it would probably be a bit warmer and more durable for those activities. It also has a helmet compatible hood if you need that.

So it really just kind of depends on what your use is going to be. Me personally, I'd probably go with the Theta AR because it would have the ability to be used in a wider array of activities but thats just me.

managed to lose a few pounds so all my gear is a size xl and i feel like i can swim in it. anyways im 6 2 and 170 I would need to leave some room for layering up here it gets quite cold.. should i go with the large or medium?

Responded on

measure center back to wrist-medium is 34", large 35" if the sleeve length works in Med do it, but I'm guessing you'll fit a large better due to your height and corresponding wingspan.

I'm not sure I could wreck this if I tried...

Obviously this thing has high praise but I thought I'd throw my .02 in. First off I got this thing half off retail otherwise I don't think I could justify dropping 500$. The label does say "made in Canada";I know there has been great dispute over the product manufacturing. As for sizing, I am 6'2 210lbs and the large fits like a dream. For those of you who wear skinny jeans and girl shirts you might think that I am crazy but for those of you who use the product as intended and are not just name dropping or making a fashion statement then I would say (at least for the large) that it is a true to size fit. The hood is very big but the cinch cords make it fit just fine especially when I wear a ball cap. The length is definitely long in the back which is great. The craftsmanship is top notch. I do wish there was a second zip on the main zip but thats just being nit-picky. It is definitely a heavy jacket compared to most but this thing is absolutely bomber and a true necessity when you are dealing with the lovely (SARCASM) Alaskan weather with weeks... not hours or days of rain.

Outdoor companies don't seem to think I exist... I'm a 5'5", 126lbs man (an endangered species, i guess because there's not enough demand to make an xs jacket for us). Would a small in this jacket fit me? I have a real problem getting small mens stuff to fit me. (I'm not wearing a women's jacket and i'm not shopping in the kids section, so don't even suggest it) Does arc'teryx run small, fitted, tapered? If not, can anyone suggest a brand that does?

Thanks in advance, Cillian...

if any outdoor product is going to fit your trim frame, it's Arc'teryx. And they make the Theta AR in M's XS, in all the colors. The challenge is to find a retailer that carries that size, but if you look around, you can certainly find someone to special order it. Backcountry.com may do it for you-talk to the Gearheads to see if it's an option. One other jacket to consider is the Beta AR, which is a shorter cut jacket (but not too short) and may work better for you, unless you're looking for maximum derriere coverage, which the Theta AR provides. One note to consider, the 2010 Theta and Beta jackets have a new pattern that seems to fit a bit more trim in the torso, but still have room for layers.

I think Brandon is right on the money here. I would go with a size small in this jacket, it should fit very nicely on you.

Cillian, first of all this jacket is awesome. I have the Candy Apple Red and its pretty well the best looking jacket I have ever seen. Its light, durable and Im stoked to go alpine and ice climbing with it this winter. In terms of size, I think this jacket fits a bit big. This is emphasized by the AR denotation, meaning 'all around' so you can do whatever with it. Its meant to be layered with. I find I have to size down with arc for the 'slim' fit I like. I am about 6 feet and 160 and the small fits great with a t shirt but can still handle a down layer ect. I would go with the XS because I think you would be swimming in the small.

Hope this helps!
