In addition to waterproof breathable Gore-Tex Pro material, Arc'teryx gave the Men's Theta SV Jacket an extra-long cut to provide even more protection in horrendous weather. Plenty of thoughtful design features help make the jacket your shelter from the storm on any alpine climb or ski tour.

  • Seal the helmet-compatible hood over your helmet or hat, cinch the laminated cuffs, and pull the WaterTight zippers tightly shut for an impenetrable fortress
  • No-lift gusseted underarms ensure the jacket won't ride up as you raise your ice axe or plant your ski pole
  • Laminated hand pockets sit above your harness for easy access
  • Slightly looser athletic fit accommodates any layers you need under the jacket
  • Laminated underarm vent zips let you stay dry as you crank the engines into high gear on your final uphill push

Absolutely bomber!

This jacket is so insanely nice. I know the price is steep, which is why I got it on sale. The gore tex pro shell is very durable, yet the jacket packs well and is fairly light. The cinch cords around the midsection and waist are very nice for keeping drafts out. Huge pit zips dump heat quickly. Storm hood is awesome for keeping your dry and shielded. the hood is very adjustable and fits well over a helmet. This jacket will not disappoint. It saved my bacon in nasty storm on Rainier. Sheds precip and blocks wind like no ones business. 5'10" 170lbs, small fits well over layers.

Theta SVX

New for fall The Theta is replaced by the Theta SVX. uses new gore tex laminate and N150 p fabric gets replaced N80 pX. Oh yeah and gets a hefty price tag of $749! yikes

Theta SVX

$749.00 bones ??!? I know Arc'teryx is premiere quality, design & materials, but an extra $200.00 (36.4% increase friends) is pretty goddamn steep. has the cost of materials gone up that much? Zombie proof maybe? What gives?

Probably my last shell

    I've had many different Gortex (and Gortex wannabe) shells over the years and have always had to put up with some degree of inside moisture build-up due to physical exertion and/or ambient temperatures. So, that's what I expected with the Theta SV but was I wrong! I really tried to work up a sweat by putting on a liner jacket underneath and wearing a hat and gloves in relatively mild (48 deg F) temperatures, but it just wouldn't happen. No sweat even though I felt a touch too warm after about an hour. Given the conditions and the hilly terrain I hiked, I should have been swimming in perspiration. Instead I remained dry and comfortable. I don't think I'll ever get another Gortex shell again unless I manage to trash this one and need to replace it.

    just got it, but happy so far

      I have not even worn it skiing yet. BUT, I know people have lots of questions about sizes. I am 5'11", 185lbs with a beer gut (33-34 inch waist). I have a Medium and it fits me great. I've tried it on with an Arcteryx Atom LT and a baselayer, and it's perfect. The cut is also awesome. This is one of the longer pieces Arcterxy offers, and I wouldn't want it cut any shorter for a ski jacket. The back goes down about mid-bum.

      As other people have said, it's a fairly loud jacket. But for the protection and strength of fabric, that comes with the territory.


      • Familiarity:I've used it several times

      Amazing jacket- the material is one of the most durable I've ever seen, and the coverage of this jacket is amazing- long in all the right places. I use this jacket for mostly cold weather actitivies- skiing, skinning, etc. I wouldn't recommend using it in very warm weather as I think it's just too heavy of a jacket. The only downside I would say is that the material is pretty crinkly and loud- nothing huge, but I just personally prefer my Sabre for skiing as it's just a little softer in the cold.

      Perfect so far

      • Familiarity:I've used it several times

      Backcountry was awesome, they made my exchange for the right size a priority and I am very happy with the fit and the performance of this shell. The features are very intuitive and it becomes part of you quickly. I love that I can easily put climbing skins in the pockets, that's critical. It's seems like everything it's cracked up to be and hopefully it will endure rugged 4 season use for many years to come.

      What I've got to say-uh about the Thet-a

      • Familiarity:I've used it several times

      This is my first Arcteryx hardshell. I have my reasons for holding out so long. I've gotta say that I regret all of them. This jacket is near perfection! I picked up the jacket here at Backcountry's warehouse and headed up to Alta for some night-skinning. I love the length of the jacket, the high collar, and the big pockets! I did get warm on the skin up (I was trying to keep up with my freakishly athletic friend) so I had to open the pit zips and unzip the jacket to keep cool on a clear, windless night.

      I have skied several days in this jacket and have really enjoyed it and have kicked myself for not buying one years ago!

      I'm 6'1" and 165 lbs and I a have the medium. It fits really well but I feel like the sleeves are a little long (I realize the Theta has exaggerated length) and maybe a little baggy in the rest of the jacket? If I ever get the chance I'm trying on a Small. I really wonder if the small would fix these problems.

      No Arcteryx owner is without a justified complaint or two of scrutiny because if you pay for perfection, you demand it. Here's what I would change about my jacket: 1) Gore-Tex. I do miss my MHW DryQ. The 3-layer on this jacket is very loud and not super breathable. I tried to get dressed and leave my friend's house early without waking anyone. If it weren't for this jacket I would have succeeded. 2) Velcro on the cuffs. I am already questioning the longevity of the velcro because it seems that every time I open the cuff, insert my ski glove, and then close it, the velcro is fraying drastically more and more.

      I do love this jacket and would recommend it to anyone who isn't a ninja!


      • Familiarity:I've used it several times

      I have owned this jacket for a couple of months now. This is my first Arc'teryx piece and will not be my last!! I don't think I could find a better hardshell.

      I bought this jacket because of the burly fabric. I live on the east coast so I do a lot of tight tree skiing and skiing where 99% people wouldn't go near. Knowing this I really wanted a really tough shell that would still be able to breathe and not feel super stiff like I am wearing a leather jacket or something.

      Another huge factor for me was fit. I wanted something with some style to it. I didn't want a short tight fitting jacket that just meets the waistline like most tech shells are. I wanted more length and some room to layer as well. I am 6 feet and 150 pounds. The size medium fits me PERFECT. It is nice and long without being too long and has enough room in it to layer without looking like you gained 45 pounds.

      I have worn this jacket pretty much everyday since the temps have started to drop. I have hiked, skinned, skied, and even mountain biked with it on. All activities the jacket performed flawlessly.

      My first hard test on this jacket occurred a few weeks ago when they first started to blow snow at my local mountain. The temps were above/below freezing all night so the snow guns were blowing pretty much water with some snow. I skinned up the mountain underneath all of the snowguns and once at the top I was completely dry. I was blown away. The jacket had breathed exceptionally well and didn't make me feel like a human sauna on the way up even though I had the jacket all the way zipped up and the hood up because of the crazy conditions.

      This jacket has exceeded all expectations of mine!! I will be purchasing a pair of Arc'teryx pants as soon as possible so I can have a full bombproof setup!!

      Can't wait to put this jacket through more hell!

      Awesome shell; worth the big bucks

      • Familiarity:I've used it several times

      Received the jacket a couple of days ago and am very pleased. I'm 6'3", 215 lbs, 45" chest, 34" waist. I ran track (sprinter) in high school & college, so I exercise like a sprinter/hiker hybrid rather than a pure endurance athlete. I paired a large in the Theta SV with a XL Mountain Hardwear Monkey Man jacket and it fits great...I'm really looking forward to skiing & hiking this season. The large in the Theta AR was just a touch too small but I have the perfect amount of layering room in the Theta SV.

      Some argue against the fleece mid-layer as being "too heavy" but my feeling is, if you're in good/great shape, the extra few ounces will not make or break you, especially since a good fleece is quite warm & breathes better than a down sweater. Obviously, ounce for ounce, down is warmer (dry) but as long as you have a good shell (which this is!) that is the right size, you're good to go. You may lose a little space in your pack, but nothing insurmountable in most cases.

      Awesome shell; worth the big bucks

      Theta SV Jacket

      • Familiarity:I've used it once or twice and have initial impressions

      Just got the jacket and I'll update this once I've taken it out a few times, but I can comment on the fit. I'm 6'1" 170lbs and wear a size medium. There's plenty of room for layering (maybe even more than I expected), but like all arcteryx products the jacket is clearly well designed without excess bagginess or strange proportions. It's also pretty long, reaching 6 or so inches below my waist. I would like to see a powder-skirt (personal preference), but I do understand that there are pros and cons to that. I would also add that the jacket does seem a little stiff and "crinkly," probably unavoidable considering the bombproofedness of the materials.

      Hmm...based on your description I think I'll go with a Large. I'm a bit bigger than you (6'3" 215lbs) and I tried on the Theta AR in large and it was just a tiny bit too small to layer a Monkey Man jacket underneath. The SV sounds like it has the extra space I'm looking for without having to jump up to an XL. Do you feel the SV is too heavy for spring hiking? I plan to use it on the slopes but do you think it's too heavy for spring hiking based on your feel?

      I agree on your sizing. I do think that this would be overkill for spring conditions, but it is GoreTex, which always breathes well. Personally, I prefer minimal gear in the spring (unless it's raining...).

      Warning large equals double X

        This only gets two stars because the overrated arcteryx can size their gear to accomidate regular people. I am 6 1 200 athletic and wear a large in EVERYTHING but this was humungous. I know some of you that love this brand will try to defend by saying its for layering, but I could fit two down jackets under this thing and still probably have room to squeeze another. The only other brand that has disappointed me like this was patagonia which pulled the same sizing issue on a seperate jacket I also returned. I understand room for layering for winter but I have a large in another arc jacket and the size difference is at least double. warning to everyone. Useless unless you try it on before.

        I'm not in love with this brand (they fit me well and do a lot of things right, but not my favorite) and own this jacket right now as my all around piece. At 6'1" 190, not super athletic body type, I bought this jacket in XL. It looks a bit ridiculous with just a T-Shirt underneath, or even a couple light layers. I will be picking up a better fitting shell for warm weather activities. That being said, this fits my XL Rab Nuetrino perfectly (8oz/800fp down), without much room to spare, and that's not even the bulkiest of down jackets. It is definitely cut larger than most shells, even winter-specific shells, but I doubt you "could fit two down jackets under this thing and still probably have room to squeeze another." And mine certainly doesn't fit like a 3XL.

        You shouldn't give a piece of gear such a low rating based on personal sizing issues. This is the SV, which stands for Severe Conditions. This is made for the harshest conditions Mother Nature can through at you. This jacket was designed for mountaineering. The fit is Expedition fit to accommodate for large loft down jackets. You size up or down accordingly to fit your application of the jacket. If you're looking for a slimmer fit, go with the SL or AR.

        Not to be rude B Real but in the future you really should do more research when adding to your gear collection. My advice is to read through the reviews of products your interested in online at retailers like Backcountry or REI. More often than not you will gather a ton of information to better equip you in making future purchases. Arcteryx's website is actually excellent in the way of writen and graphical representation of the sizing and fit. For example go to Arcteryx's page for this product ( and I qoute.. "Our toughest and longest length waterproof GORE-TEX� Pro Shell jacket. Sized to accommodate extra layering for extreme weather conditions." and if you had clicked on "Sizing Chart: Men's Expedition Fit" it clearly explains.... "Cut roomier than our Athletic fit and suitable for winter/extreme conditions, Expedition (XPD) fit garments are cut larger to accommodate multiple layers without binding or restricting movement.". I agree 100% with what Mitch stated previously. This jacket is trully phenomenal. The fabric and constructon is second to none in its category. This shell will perform as expected for a decade or more if it is maintained properly. In fairness Ive ordered some items online and after trying it on it fit like hand me down or even worse fat man in a little coat. Frustrating as that is I didnt go online and undermine a products ratings especially if it was due to my negligence. This shell does exactly what it is designed to do under conditions that require versatility. The shell looks great doing what it does out in the elements protecting you and your layers. I appreciate this shell for what it is and how it flawlessly performs not for the logo sown on the chest.

        Couldnt change the actual star rating the site wouldnt let me for some reason. Valid points from all. Second ARC purchase, was just amazed at how different the two jackets were for being the same size.

        ******Changed to four stars because it is unfair to lower the average rating. Its a great coat and will do the job its supposed to well. WARNING to all not shoving a giant puffy under this SIZE DOWN. My fault for having smaller insulating jackets.

        I forgot one important thing when I read these reviews to try and figure out my size. Most men under six feet add about five inches to their height, even on the internet apparently. So don't listen to the drivel about getting a medium if you are six feet or taller. A medium= a medium if you want the jacket to fit the way it was intended.

        So i must retract my apologies to the other commentators due to the fact that like they said reading is key to this. Well it says Slightly roomier not a lot roomier fit. Bit misleading Sorry i didn't go to 8 sites to know that this would be a huge size differnece for my needs.

        I will be keeping the star rating at a two or a three however due to the fact that when I read a product review I dont want to read how wonderful it is I want to know what I may run into that I may not like. Usually not included with 5 star reviews. Star ratings dont make a product worse it just is there to inform others with helpful information.


          This jacket is awesome. As far as the sizing goes, if yo u have tried on a theta ar and liked the fit go down a size. I tried the theta ar in xl and the theta sv in l and the fit was pretty much exactly the same ( same length in arms and torso girth MAYBE a half inch shorter in the front length but not really noticeable). Only get your regular size if you want to put some serious layers under it (I know this is what it was designed for). The fabric is very tough and better performing than the ar version (ar only has this fabric in certain places). I am keeping the ar version do to its versatility and the drop hood. The hood on this thing is better for severe weather but overkill for what I do. The drop hood is much more comfortable.

          A note about fit: Remeber that most men who claim to be 6'1" are really only about 5'8" so if you really are 6'1" get at least a large or the jacket will ride half way up your ass. I don't know what you people are talking about who say a large is a double xl and that if you're over six feet tall to get a medium. Get your correct size and the jacket fits how it's supposed to.

          Beware of sizing

            I ordered the medium Theta SV at first. Im 179cm (5'10") 165lbs and an atheletic build. I wear a medium in all arcteryx shells/softshells. The Medium Theta SV is quite generous in its cut. Coupled with the extremely long cut and the size just felt wrong. When compared to the previous Theta SV it was more than a 1/2 size larger in the medium and when copared to the Sabre sv (loosest fit of all my jackets) it was still larger. Finally I ordered the small and im glad i did! perfect fit (small Theta SV is pretty much the same size as my medium Alpha SV but longer in the front and rear).
            Now about the jacket. The sillouette is perfect. Excellent pocket placement (away from shoulder straps and waist belts). roomy enough to stash my gear. Arms have ample length for my monkey long arms. Excellent articulation in the arms so your cuffs dont ride up. Hood is large and fits over any helment and can be cinched down so it does not flop around. Internal mesh pocket was a nice additionto stash larger objects.
            Overall great jacket. As good or better than the previous Theta SV and prefer the Theta SV over the Alpha.

            simply the best

              i am a nyc resident and i am loving this jacket because everyone else is loving this jacket. it is roomy and comfortable. most importantly it does the job in the rain. so far it is perfect. can't wait for cold weather to arrive. It layers so well. I will be getting the sidewinder next. i have the micon jacket as well and i cannot wait to wear it

              Finally an ArcTeryx Jacket to Love

                Originally I had the XXL version but, it was huge so I sent it back and got the XL. So far I've been out in a driving rain/blowing sand storm and was dry and comfortable. The GoreTex Pro Shell is as close to bomber proof as you can get. If you are planning on wearing a harness, I would probably steer you to the Alpha SV. Either jackets are in the same league.

                Great Jacket, Crazy Price.

                  This jacket is definitely roomier than others that I've tried which is what I was looking for. If anyone is wondering about the squid ink color....take a blue ball point pen and scribble a mark.....its exactly that blue-ish with light purple glow to it. Definitely not the purple the pictures are showing. Coughing up the money for this coat blows, but It fit me better than anything I had tried so I went with it. (6'1, 190, Sz Large)

                    Also, how do the Theta SV and Alpha SV compare sizing wise? I'm 6'1" 240lbs with a 52" chest - should I go XL or XXL?

                    The Theta SV fits about a full size larger than the posted size. My small Theta SV fits exactly the same as my medium Alpha SV. Even when comparing them on top of each other the Theta is just as wide and a touch longer in the torso. Best to try one on before ordering (or you can order both sizes and return the one that doesn't fit to backcountry

                    I'm debating between the Theta SV and Alpha SV. What's the difference between the 150D nylon of the Theta vs. the 80D nylon of the Alpha? Is the Alpha softer?

                    Best Answer

                    The Alpha SV uses the newer n 80 X-P fabric. It is more supple than the fabric on the Theta. Both are extremely durable and have the same performance.

                    Next season the Gore Pro membrane becomes available (20% more breatheable) and the Theta SV apparently becomes the Theta SVX (I heard they will be using the same fabric as the Alpha)

                    To add to Paul U...I spoke with Arcteryx and they said that the Theta SV will indeed become the SVX, using all n80 fabric like the current Alpha SV. The Theta AR will be a combo of the current 40d and will have n80 for reinforcement vs. the current AR's 150d.

                    What is the difference between this jacket and the Theta AR?

                    Best Answer

                    1. The SV is fully reinforced (150D fabric), the AR is not (the AR is reinforced in high wear areas like the shoulders and sleeves)... therefore the SV is more durable and will last longer (but also a few ounces heavier).

                    2. The SV has an expedition fit (wider) than the AR (athletic fit)... although the SV has a waist cinch that can make it fit more like an athletic fit.

                    3. The Ar has separate collar encircling the neck while the SV does not. I find this collar annoying when wearing a layer under that has a hood (but that's personal preference I guess).

                    4. The collar on the SV covers much higher on your face than the AR (it is an SV after all).

                    5. Price difference of $50. But then again, at this price range I don't think $50 is a big deal.

                    Hi I'm 5' 11" and 230lb. The largest part of my body measurement is my waist and it is abt 46". Should I go for XL or XXL considering I need to layer a fleece and a t-shirt?

                    Hello rivest,

                    I am 6' 1" tall and at the time I had aquired my Theta SV size XL I was 262lbs and had a 40-42 in. waist and there was plenty of room in the waist and I can imagine you would have a problem. The cut of this shell is expedition fit which means its cut roomier for layering. It all depends on how you plan on utilizing it. Do you plan on wearing alot of layering for winter activities like a baselayer and a puffy down then you might look at the xxl. At this time Im 220 with a 36" waist and can easily wear a baselayer, Atom Lt under my Atom SV with the shell on top for extremely cold conditions. The great thing about is they have an excellent return/exchange policy so no need to worry. Hope that helps you get an idea of how roomy this shell is. Great piece of gear you will love it! Ps. I just measured across the face of the shell laying flat and its 26.25"across, pleanty wide.

                    what are the major differences between the theta AR and SV. for $50 more am i better off getting the SV?

                    The Theta SV is built entirely of a more durable fabric (N150p GORE-TEX Pro 3L) and the Theta AR uses this fabric in the high wear areas like the shoulders. The cut of the AR is more athletic and the SV is cut roomier for layering. I own the SV and use it mostly in the winter. Any other season its really too much coat for the purpose it serves. This coat will hold up to just about anything you throw at it. The AR is a great coat too. If you want the biggest bang for the buck go with the SV. It will not dissapoint. Find a local retailer and try them both on and that way you can compare fit and feel.

                    My trusty Stoic hardshell recently bit it after 5 years of faithful use.

                    I'm now looking for a shell to last me the next decade. I live in the Pacific NW so hardshell is necessary given our weather.

                    I get in about 30 days of snowboarding a year (mostly resort, but I started doing more backcountry towards the end of the season).

                    I've started to get into mountaineering too. Mainly non-technical ascents but I'd like to get into more challenging stuff as my skills progress - ice climbing, etc. Oh, snowboard mountaineering is a definite goal as well.

                    I want to rely on ONE hardshell for everything. I'm considering either the Alpha SV or the Theta SV. It seems the main differences are:

                    Theta has bigger pockets (beer!)
                    Theta is longer

                    Are there strong arguments in favor of one or the other for my use? Does the Alpha's shorter length get annoying for skiing/snowboarding? Does the Theta's longer length interfere w/ harness?

                    Oh, and why doesn't bc carry the Sidewinder SV?

                    The Theta SV will be your best bet, as it's more versatile, especially for the down portion, and for more layering options. The Sidewinder SV will be back on when the new styles fill in for Fall '12 around mid september. Sidewinder wouldn't be as good as Theta SV for the climbing ventures.

                    Wish I could comment on Brandon's question. The alpha sv description said something about a climbing harness keeper loop. Does the theta offer any similar advantage or is that just compensation for the shorter length? By the down portion you mean it covers your butt with the drop back better? By layering you mean it has a more generous fit?

                    THe alpha SV has a hemlock harness holder around the side of the bottom drawsting. Small piece of foam (about 5" long) . It is supposed to help the jacket from rising up or rubbing along the sides. I prefer the Theta for skiing, but for climbing the Alpha is better (shorter cut helps as well).

                    I'm 5-7 150, Would a small be good for my needs aka backpacking, biking, heavy use.

                    Hello, for a all around jacket for...

                    Hello, for a all around jacket for snowboarding\sking, hiking and general around town for all seasons , would you recommend this jacket over the Crossbow or Sabre? I want to be certain that this jacket will work will on the ski slopes since it does not have the powder skirt. Also, how is the squid ink the color too purple? Thanks.

                    Thanks. What about the color Squid Ink? I read from the reviews here the color is more blue with a small purple tone? Also, i am 5'10" 180lb and 32 in waist and 41in chest should I stay with a medium. The crossbow and sabre medium fits me fine with room to layer.

                    Hi Paul, Could you elaborate on the color as compared to Bondi Blue, Micro Blue (which you own)and the Blue Ray I have on my Crossbow, which I think is a bit more subtle . I wanted to use this jacket not only as a ski jacket on the slopes but also wear casually around town. I just wanted to make sure the squid ink is not too flashy or girlie for a lack of a better word :-)I could not try or see this color jacket in person as my local shops does not carry it but I did see the Sabre pants in squid ink color and though it was pretty purple looking. Also, would the carbon copy Sabre pants match will with this squid ink color jacket? I hoping to return the Crossbow and get this jacket to use for all seasons. Thanks again. Jeff

                    The Squid ink color is the exact same as you saw with the Sabre pant. It is certainly not a girly color (I would almost consider it a grape purple). I own bondi blue, Miro Blue and Blue ray jackets and I find I take the Theta around town the most of all the jackets I own. I do find I get a lot of compliments on the color since it is very different.

                    Paul, how would you compare the Theta SV to your Sabre for sking on the slopes? Does the non powder skirt on the SV bother you? I want a shell that would serve all outdoor activities purposes and wonder if it would justiy the cost to own the SV and Crossbow.

                    Powder skirts are a nice touch on a ski specific coat but a pain sometime when wearing it around town. That being said the Theta is a nice ski coat. It provides ample coverage and has some great articulation. I sized down to a small on my theta since I tend to layer less with it.It also functions as a perfect 4 season coat (my sabre and stingray are not great in warmer weather) The sabre is a touch warmer with the fleece backer and the fabric is much quieter. The pockets of arcteryx Whiteline series of jackets are also roomier than the theta which is nice for skiing. If you can afford it stick with both jackets (you can never have too many IMO).

                    Sorry, more sizing questions as I am...

                    Sorry, more sizing questions as I am concerned about dishing out so much on this jacket, particularly forwarding / shipping costs to Tasmania, Australia. I am 5'9" & 170 lb, athletic build (wide back, I often find gear fitting tight under the arms). The most I would layer under this jacket would be a baselayer t-shirt, smartwool mid crew & a windstopper vest. Some (further) advice on sizing would be very much appreciated - Medium or Small size??? Thanks in advance :-)

                    Your in between a small a medium. My Small theta SV is the exact same size as my medium ALPHA SV (2009 version) and very close to Medium Sabre SV. I started out with a medium Theta SV and switched to a small (5'10" 165lbs). You should try it on somewhere just to be sure. They are VERY long jackets in the front and back. You could save a bit of money and look at a medium BETA AR.

                    How is fit and length of Theta SV medium...

                    How is fit and length of Theta SV medium compare to Sabre or Stingray?

                    I'm 5"10, 160lb and Sabre Medium is just good fit for me.

                    Is length of Theta longer than Sabre?

                    I am 6'3 and my weight fluctuate between...

                    I am 6'3 and my weight fluctuate between 260-270. I have a big chest and broad shoulders. Usually XXl doesnt even fit but based on these reviews this jacket is huge. Should I go XXl or XL?

                    The Theta SV is sized to accommodate layers for quite cold conditions, so even if you'll be wearing big puffy jackets and fleece under, an XXL should be fine. It does have quite a bit of volume in the torso. There is a sizing chart just below the 'Option" button and that will be a good guide.

                    Is this jacket too heavy to wear in the...

                    Is this jacket too heavy to wear in the summer rain?

                    You can wear this for a summer rain jacket, as it's Proshell, so despite it being super durable, it's not super heavy. If you only plan on using it for summer, you may be better served by the Alpha LT. For a year-round jacket, the Theta SV is great and it will serve you for many seasons.

                    It's hard to choose size for this jacket...

                    It's hard to choose size for this jacket and Alpha jacket. I am 6'5'' 200 lbs and 43" chest 33" waist. Which size will you suggest for Theta sv jacket? L or XL and how about Alpha jacket? thank you in advance~ peter

                    Is the Naranja color an orange? And what kind of an orange it is? Thanks.

                    My chest size is 38", waist 35". What size...

                    My chest size is 38", waist 35". What size should I get? Max of 2 light layers.


                    The theta SV runs very big. I own a lot of Arc shells and this is the most roomy of all of them. I have a 40" chest and have a medium and have room to spare- the waist area is also quite roomy and I have to cinch up a lot at the bottom. I can probably get a small and have no problems layering. Go with a medium (BTW these are also very long in the Torso)
