Here's what others have to say...

Are there really no pockets on the inside? My primary use for an inside pocket is ipod/headphones. Would that work somehow?

Responded on

nevermind, I checked the arcteryx website and it does have one internal pocket

What is the difference between Gore-Tex Pro 3L and Gore-Tex Performance 2L?

Responded on

ProShell uses a woven backer to protect the Gore membrane from the inside, while Performance shell uses a knit backer or a urethane coating; in the case of 2L there is a hung liner to protect the membrane which adds a bunch of weight and bulk to the jacket.
The woven backer is more breathable, a bit lighter and much more durable than the backer on performance shell.The 3L construction means the face fabric, Gore membrane and backer are laminated into one piece of fabric instead of having a separate liner material inside the coat.

I am 6'1" and 198lbs. I am a Large in all of my Arc'teryx jackets/fleece (Alpha LT, Fission SV, Fission LT, etc) but from what I have read, is the large going to be too big? Should I get a medium in the Theta AR?

Is that specific offer the tight fit model of 2011 or the more loose fit cut version of 2010 and previous?

Cheers, Florian

Responded on

If you're referring to sale prices, that would be for 2010 Theta AR model. None of these would be considered tight fit. They all have room for layers underneath. The 2011 version has a bit softer feeling face fabric, that is still bomber, a Vislon watertight front zip, and a layer-ready fit that is not too baggy without layers.

Responded on

The previous Theta AR before the 2010 redesign were much baggier. The ones that Backcountry has on sale are the current version. They are by no means tight- they have room for layering. They new fit is much better.

Posted on

This is a great jacket! I use it for everything, (commuting, back-country skiing, walking the dog in the rain).

Is there a jacket with similar cut, that offers good wind breaking capacity and breaths better?

Responded on

The new Beta FL and AlphaFL have a longish cut (but not as roomy) and is supposed to breathe better than proshell. Otherwise you may want to look for something without a laminate coating (perhaps just a windshell)

5 5

Needs nothing.

6' 150lbs - Size Medium

Not much to say here.
Arcteryx seems to be the only brand that still fits a slimmer crowd. Sure is costs more than a decent car ... but it's worth every penny.

Light. Functional. Perfect.

Could use a powder skirt ... but not really. They have other, heavier, ski specific jackets with powder skirts.

Does anyone wear this jacket with jeans...

Posted on

Does anyone wear this jacket with jeans as just a rain jacket? Or is it too heavy duty for that? How about the Theta SL? Price is not a factor AT ALL.

Responded on

Hey! Yeah, I use this jacket as an all around-er... It is a heavier denier face material so it will be warmer... Also remember that the Theta line is the longest of them, meaning it will probably cover your butt... The best all around, in my opinion, is the Alpha LT... I also use the Alpha SL pull over a lot...

Responded on

Johnny, same as Dean, I wear it all the time with wind pants and jeans. It is very long though so I tighten the hem cinch cord so it doesn't hang so low.

Responded on

This jacket can definitely be a great rain jacket (it has essentially no insulation whatsoever). The Theta SL doesn't breath as nicely as true 3 layer gore tex (it's "PacLite") and isn't nearly as durable. If you leave an SL at the bottom of your pack folded the same way long enough it will wear through just from wiggling around.

However, I have this jacket and an Alpha LT which is considerable thinner and weighs ~120 grams less. My Alpha LT serves as my rain jacket and a lighter more packable alternative. My Theta is a tougher ski jacket. The only thing about the Alpha LT is that is doesn't have a collar like the Theta and is a bit shorter. Both options are very light though. I just live in New Mexico where I pull a rain jacket out of my packet one every 2 years.

That being said, you can't go wrong either way ... except with the SL ... GoreTex PacLite is meh IMO.

Oh, hey ... Dean Whitehead agrees ... Alpha LT all the way.

If you're a climber the Alpha LT kicks ass with its little removable foam inserts that keep it from pulling through your harness.

Best rain jacket (for me) to date

I know it looks pricey, but every piece of Arc'teryx gear I've owned has been worth every penny, this is no exception. The Pro Shell is gore-tex, it doesn't let in a drop. The pockets are well placed and very accessible when carrying a pack. It packs down to about Nalgene size, has PERFECT drawstring adjustments to add the custom fitting touch to anyone. I've NEVER in my life owned a shell that fits me this well. I am 5'9" 130 lbs. and I got a small, the shoulders/pits leave plenty of room for layering even if you get your size.

It's pretty amazing how much this shell accommodates layers but then cinches down to a slim fit rain shell. I layer the Atom LT (size S) underneath for light coverage and the Atom SV (size M) for super warmth. Neither one has any problem underneath, although I wish I had gotten an SV in size small. I CAN also do both the LT and SV together or either one with a 200 wt fleece. The last two combos are serious overkill, and would only be used in seriously cold conditions, but are possible and comfortable, not too bunched or immobile.

The pit zips are the best, with double zippers on both sides, you can adjust to whatever ventilation size you'd like, I tend to leave them slightly open in the middle at all times, this also enhances mobility, especially when layering.

The hood is pretty amazing, as previously mentioned it is huge, that is so it can accommodate a helmet comfortably, which it does. It also cinches down to the perfect size for my head, and then just my eyes poking through for SERIOUS conditions. Pretty damn amazing.

I was going to buy an Arc'teryx shell either way, the selling point for me on this specific shell was the length. I have found that the other Arc'teryx shells are just too short for me, this jacket is probably another 6-8 inches longer than the Beta or Alpha series. That being said it offers more protection from the elements. For me this was a no brainer after I tried all three on side by side. I was actually surprised at how short the other jackets were. Something to keep in mind though, the Arc'teryx articulation on the sleeves is perfect, the sleeves and waist never ride up, so if I had a shorter cut, ride-up should still not be an issue.

I got this jacket on sale for about 300, STEAL if you ask me, the $500 is steep but no doubt, you get what you pay for.

Full Protection

This is probably the best jacket for anything that requires full protection with no fuss, just function. The design is quite simple but very anatomical and easy to move in. Of course this jacket makes a ton of noise just like every other hardshell jacket; this is why I don't wear hardshells except for in the most severe conditions. The seam taping is absolutely the best I have ever seen and the waist adjustment is quite nice and in my opinion a necessity. I prefer the drop hood to the attached hood featured on the sv, it is huge with a strong brim just like every other arcteryx shell. Dont expect this to be an everyday rain jacket, if that is what you are looking for pick up something like the nau rebound (that's what I use on rainy days), but if you are looking for full protection this is the way to go. I suggest sizing down unless you plan on fitting a subzero down as a midlayer.

Is the fit the same as the Theta SL? Or is this slimmer or shorter or what?

Responded on

The Theta AR is longer in length than the SL. AR is thigh length, while SL is hip length.

Responded on

The theta AR has more room than the SL. I can definitely fit more layers under my AR.

Awesome Investment

I have waited a long time to pull the trigger on this expensive a jacket. I am very happy with everything about this jacket. Great fit, well made and very functional. Skied i the rain at alta with my Brother, he was soaked, I just sat there in my dryness... I am looking forward to using this on some camping trips this summer!

Nice work Arc'teryx!

Ok let me explain. I hate to be the kill joy in this pretty boy party, but lets get real. Have you seen/worn this overrated trash bag? Arc'teryx has a name for a reason and this jacket they make today with ProShell is NOT where it came from. In a extreame effort to save a few ounces Arc has all but lost what made it worth the money. Are you buying this having worn, felt, and seen the older Arc'teryx XCR shell? or are you just saying to yourself that it's just gotta be the best they or anyone can do? I have both and can tell you that the two jackets made by the same company have no business being on the same mountian together. It's the difference between building it so it will last forever and building it so you'll need to buy the new model in a few years. ProShell is so paper thin and weak that holes are now a thing to just get use to. Also I guess stiches are too heavy these days so we'll just glue the entie thing together....? The glue will fail as it has for me. The XCR has it glued and stiched. I wish you all could hold, feel, and wear the older XCR before buying the ProShell, then look at the sales man and say WTF DUDE!!! This is for all of you that are really going to use/depend on it like back country ski/snowboard or mountianeering folk. the rest of you can grab the nearest hefty and hit the bunny slopes for all I care.

Responded on

All Arc'teryx products have a lifetime warranty, if you send them the jacket, they will repair it at no cost. If they cannot repair it, they will replace it. I would love to try out the XCR version considering how much I love this version. I am sorry that this is your experience with this jacket, I love it for everything I've used it for.

Responded on

You can still find the XCR for great deals on Ebay. just buy one. you'll spend about $200. I recently bought a like new sidewinder XCR and is the most beautiful Arc I have to date! if you don't like it you can resell it for the same price. I love Arcteryx and own lots of thier gear. beautiful stuff. Wish they would make it all in Canada so that I atleast understand the price better or lower it for the China crap. I'm not a Arc hater, But I think you all should know whats going on since not many people on here have a clue how the bird made it's rep and now demands the premium retail.

Responded on

Let's see, BC has a lifetime warranty and Arc'teryx has a lifetime warranty. Why don't you do something about your jackets issues instead of being an attention ho?

Responded on

lol it's not about attention. It's about telling people that you can do better. The new soft shells are still great and will hold up well. If you just wanna feel all warm and fuzzy inside about spending a ton of money on a product with a good warrenty then go for it. For me its not worth the down time sending anything back to the manufacturer. I'll glue and patch it myself. I'm giving people valuable information so that it's an informed purchase and not a ignorant one. That being said I do believe that out of all the flimsy light weight shells on the market that this is one of the best. For best results I would say to skip this model and go strait to the Alpha SV. the build quality is their best and is made entirely with the thicker face fabric.

I am concidering purchasing the Theta AR jacket but am concerned about fit. I have a 50" chest and am thick through the shoulders and arms and will use the jacket as a four season so will need to layer under it in winter. Any help out there?

Best Answer Responded on

Dan, I have a weightlifters build and do not have any problems with this jacket. I am 5'9" and 195-200 and I bought the XL to give me some room in the back area and also allows me to layer.

I have an opportunity to buy this jacket, but there's nowhere to try it on my area.

I have no plans to layer underneath, besides a base layer or t shirt, as I'll be using it for hiking/trekking in Central America, mostly during rainy season for the next 1-2 years. I need it to fit snug and not be baggy.

I'm 6 ft 2 in and weigh about 175 lbs. I was told a medium would be a good fit as the large would be too baggy (remember I'm not skiing or using this in any cold weather environment), and I tend to agree but am concerned about the length of the sleeves. I wear dress shirts with 34" arm length, hopefully the medium will provide enough length in the sleeves? Please help me out so I can decide whether to pull the trigger on the medium I have the opportunity to buy at a considerable discount. I feel like if I get the large to ensure long enough arm length, it'll be too baggy (which is huge concern for me). Thank you for any help!

Best Answer Responded on

If you can get away with a 34" sleeve length at your height, with no heavy base layers to speak of, whoever told you to go for the medium was exactly right. "considerable discount"?...pull the trigger because it sounds like you're all set. Enjoy!

Responded on

Thanks. I just bought it. It's a pre-owned, hardly every worn and I have 7 days to try it and see if it's the right fit, if not full refund -- very nice seller. Hopefully it fits.

Is the hood stowable?

Responded on

No- The hood is fixed and does not roll up in the collar like some other models. It has a 3 way adjustment on the hood which can be cinched pretty good.

What size should I ( Large or Medium) get for my boyfriend. He is 6'4" and about 175lbs?

Best Answer Responded on

I would try the Large first. I think the sleeves on the Medium would be too short if he has really long arms being 6'4".

should the fact that this jacket has no powder skirt be a deterrant not to buy it for snowboarding?
it does hav a draw cord hem doesnt it which should do a decent job of stopping snow coming in?

Best Answer Responded on

It has a draw cord at the hem as well as an inner cinch at the waist. Its a versatile 4 season shell. It also has plenty of length in the front and a drop back hem so it provides plenty of coverage. If a powder skirt is necessary look at the sabre SV or Stingray models as they are snowsport specific shells.

another 5stars

Just adding my 5-star review to the dozens of others. This jacket performs, and the material is great. Never turning back from Pro Shell, and Arc' just makes sweet equipment. I like lots of other companies for different things, but my favorite base, mid, and tech shells come from Arcteryx. Only negative on this jacket for me is my use of the theta AR as a snowboarder: I wish it had a powder skirt. But that's my fault for buying a jacket without it!

Posted on

Trying to decide between the Theta SV and Theta AR. Is the only difference the weight of the fabric? Is fit identical between the two? Any details very appreciated.

Best Answer Responded on

I had the same decision to make a few months ago. I unfortunately can't tell you the differences, or similarities of the two. I can tell you that the AR rocks. I really like the lightweight fabric. It is nice and thin, without feeling flimsy.

I have noticed the hood design is different. I like that the hood on the AR is attached around the collar. The collar is separate to the hood, not part of it, as it is on the SV. It may only be a small thing, but as I rarely use the hood, I like the way it sits on the AR. Not sure I'd be as happy with the one on the SV.

I bought it mostly for skiing. It passed with flying colours being worn everyday for 5 weeks in Europe. The real test is likely to come this southern winter. Slush and rain falls more than snow down here in Aus.

Sorry I can't give you the info you are after, but I don't think you'll be disappointed if you get this (or the SV for that matter).
