Top notch Arc'teryx quality/performance but flaws
January 10, 2011

When you buy an Apple computer, you know what you're getting. TOP notch build quality, beautiful design and impeccable performance. Same can easily be said for Arc'teryx products, these snowboard bibs included. However, a few minor design decisions and one glaring oversight exposed after a few outings prevent me from making these pants the greatest of all-time. Pros: Arc’teryx construction Heavy duty reinforcement around high-stress areas 110% waterproof 200% windproof Cons: No side pockets AT ALL No buckles on bib straps JUST a shell, no insulation (can be argued that this is by design) Expensive The lack of side pockets on these pants are the single (and only) frustrating feature of these pants. I think it goes without saying that ANY pair of pants should have side pockets. After taking these pants out for 3 or 4 outings, I can't remember how many times my hands have instinctively reached to the side trying to pull out a trail map and been met with disappointment that, yeah, there are no pockets!! There are however two very small zippered pockets towards the top of the bib, pictured in the product photos. They're great for holding a tiny wallet (ya NEVER want anything hard or sturdy in a pocket between the ground and your body god-forbid you fall directly onto your chest and the camera or radio or iPod cracks your sternum). However, they're useless for anything else! Because this product is a bib, these two pockets are placed very high, which means if you want to access anything in these pockets to have unzip your shell, unzip your inner vest/fleece, pull-up your pullover, then get at the pockets. Extremely inconvenient. Really wish there were buckles on the bib straps as well, very difficult to have to go number-two in these pants and be forced to strip off everything you're wearing over it just to take off the straps and pull down the pants. Front zipper runs very high up onto the chest, so again, having to go to the bathroom involves an awkward reach up under your pullover to unbutton, then unzip. With all this said, there’s no doubt in my mind that these pants can be wrapped around 4 pounds of dynamite, detonated and come out the other end in returnable condition. Construction on these pants is heavy-duty and top-notch. Arc’teryx took care to really fortify the heels of these pants, lots of scuffing and scraping on this often exposed area of the pants can really take a toll. Great pair of pants, would definitely recommend to a friend accompanied by a stern warning of “be prepared to work around the lack of pockets and high zippers and you’re all set!

Amazing product
October 23, 2012

I've been using these pants for three years now and have nothing but positive words to say. I use them in a variety of sports, activities and conditions, but primarily for mountaineering, and backcountry and resort skiing. They are incredibly durable and, after three years of use, are still in great shape. All the high-wear areas are reinforced with stronger fabric or extra stitching and this extra quality has made a huge difference. The different size and inseam options also make for an excellent fit. I have a short inseam and had not previously found shell pants that fit me satisfactorily. These do and it is a pleasure not to have extra fabric hanging down over my boots. The full length zipper allows me to regulate temperature very effectively and seals out water without any issues. The only critique I have is that I wish the pants came with a small strap to tie the internal gaiters around the bottom of the boot. This would be a nice addition, as the internal gaiters do have rivet holes for such a strap. All in all, an absolute 5-star product.

Bomber bibs
December 07, 2012

As a member of Gore MountainTechs, I have the opportunity to field test GORE-TEX gear in some of the harshest conditions...and these bibs are amazing. They're lightweight and packable, yet thick enough to stand up to tough abrasion on rock/ice. They articulate well in the knee and hip, but can sometimes bunch up in the crotch when high stepping...just the nature of the beast with bibs. Extremely waterproof, have had no issues. Would recommend layering in very cold conditions, but overall excellent bibs!

Pros: Great design, Build quality, Lasts forever, Performance, Cons: Cost

Theata SV bib
January 29, 2008

Amother great product from Arc'teryx. Using these pants for winter work, they keep the elements out.(local ski hill) Size is true and the short, reg and tall options are great.

Instep to Low
January 09, 2009

I like these pants with one major flaw. The instep patches are not high enough up the leg. They do not even go up above my ski boots. I am less than a month into the use of these bibs with fourteen days of skiing and I already have six patches of repair tape within two inches of where the instep patches stop. I like the pants but am very upset that I already have small slices in my new $400 bibs before I have even had a chance to put a crampon hole in them. Find a pant with a higher instep if you plan on really using these for their designed purpose.

Great Bibs to Keep You Dry & Comfortable
December 22, 2012

Overall I have been very pleased with my Arc'teryx Theta SV Bibs, and have considered purchasing a second pair for when the day comes that my first pair needs to be retired. Activities: I have used these bibs for many mountaineering trips, ice climbing trips, and countless days of skiing. Fit: I love the fit of the bibs. I am 155 lbs., 5’-9” tall and have a 30” waist, and 30” inseam. I bought a size medium, and have found the fit to be great. Function: There are many aspects of these bibs that I really like. One of those features are the full length side zips, which I often partially zip down from the top when looking for extra ventilation. The built in gaiters are also very effective at helping keep snow out. Waterproofness/breathability: I’ve tried various types waterproof material, and have not found a product that does a better job keeping the water out while also being breathable than Gore-Tex. The fact that these bibs are made with Gore’s most durable and rugged waterproof breathable fabric (Gore-Tex Pro), makes these bibs very capable to withstand the hard ware-and-tear I expose them to. Durability: I have had these bibs for over 3 years, and they still perform like they did when they were new. Just remember that like any Gore-Tex waterproof fabric, it does need to be maintained properly (i.e. cleaned and treated with DWR). Construction: Superb, which is consistent with any other Arc’teryx product I’ve seen or owned. These are a great pair of bibs that whether it is a bitter cold day of ice climbing, or a warm spring day of skiing, they are my go-to shell. As a disclaimer, I am a “Gore MountainTech” and test products for Gore.

Best pants I've ever had
January 14, 2010

Has all the functionality I need and require (which is a lot) and until now, ski pants were fitted to a lowest common denominator. These fit better than my jeans. These are the best, most versatile pants money can buy. Worth the tariff if you have real needs in terms of functionality.

worth the money
January 01, 2010

These pants are phenomenal. Fit is a bit baggy compared to other pants. I'm 5'11" and 175lbs - the medium size, regular length has more leg room than other Arc'teryx mediums I've tried on. Chest pockets are great for smaller items like a wallet, snacks, cellphone. The Gore-tex Pro Shell fabric is amazing - breathable and not clammy against the skin.

Great product, but cut lower than I thought
January 16, 2011

Love Arc'teryx gear and this bib is no exception. First class quality and craftsmanship. However, the bib part in front was cut a lot lower than I thought from the picture, only a little higher than regular snowboarding pants. Decided should probably try the Alpha one instead, which is higher cut in the front. Fit was great and not super baggy, nor did it restrict movement.

Pros: Build quality, Lasts forever, Performance, Cons: Cost

The good choice.
April 17, 2011

I finally pulled the trigger and bought this bib after looking at it for a couple of years. Although it is quite expensive, it deserves all of my gratitude. The quality of the material used, the craftmanship, and the overall comfort make this bib the best I have ever owned. Super comfortable, ultra light; I would definitely recommend this to anyone looking for high quality hardshell for mountaineering or skiing. To bad that it is so pricey.

Pros: Build quality, Lasts forever, Performance, Cons: Cost

best ski pant I have owned
February 11, 2010

Bought the pants 2 months ago. Have used them a lot as ski/rando pants. The quality and build is excellent. don't hesitate, buy now if you want the best bib for skiing!

Arc'teryx - The Best Money Can Buy!
April 19, 2008

I live on the East Coast where I ski and snowboard local resorts in the Mid-Atlantic Region. We frequently see ice here. I also take at least one trip out west each year. This year I experienced BIG Powder. These Arc'teryx Theta SV Bib Ski Pants are the best I have ever owned. Nothing I have ever had comes close. They are light weight, comfortable and extremely durable. I am 6' 1" 240lbs and the XL fits perfect. The length is great, the built in suspenders are small and more manageable than any I have ever seen. They have a built in belt around the waist so there is no chance of snow in getting in when you are sitting down strapping your board on. The crew at Altrec is awesome also. Buy Sell or Hold? Believe me, these are an absolute BUY!

I live in Vermont and ski the local resorts (Bolton & Stowe) and these bibs are the lightest and most durable ski pants I have owned. I really like that they come in different lenths, as I am not extremely tall. I'm considering buying another pair simply for fear they won't make them in the future.

Not as good as Alpha SV
October 28, 2011

I bought this one along with Alpha SV to be able to compare the two and pick the one I like better. My intended use for the bib is skiing so Alpha from the specs seemed like too much, but I couldn't resist the reviews it was getting, so I wanted to see them both. While there is nothing wrong with Theta bib, and overall it is a great product, in comparison with Alpha it pales out. First the material feels not as durable on Theta as it is on Alpha, even though it is quality GorTex. Secondly the upper body on Theta is much lower than Alpha's and I didn't like that very much. In addition it is not so snug as Aplha's. Theta's is contoured for typical skiing position and it makes one look a bit odd when just standing up. Since I will use the bib to work around the house in winter too, I love the knee pads that are available with Alpha but not with Theta. A common issue with both bibs is the sizing. I am 5.8, 155 and typically wear medium, with Arcteryx I have to go for small/short to make either of those bibs fit the way they should. And the biggest feature that is missing on Theta in comparison with Alpha is the zipper all around your crotch. There is no words to describe how convenient it is to take care of "business" in the open if you have something like that. So while Theta is a great product overall, only $50 more buys you even better bib IMHO. And if you can't decide on one or the other before you see them, then get both and see what works better for you. You can't go wrong with either of them - it's just a matter of personal preferences in selecting one you'd like.

Pros: Great design, Build quality, Great value, Cons: Cost
