Rated 5 out of 5 by from Ultimate Protection for Legs I bought the Theta SV's to go with my Sidewinder SV jacket. Both items are listed as "our most durable item", a claim that has so far proved to be true. I have had these for 3 years, and the wear and tear of months of skiing have so far failed to make an impact on them. They look as good as they did on the first day. The high waist and back keep out cold and snow, and the thigh zips prevent over heating on long skinning sessions. I particularly like the full length zips, which have disappeared from most other pants.

Rated 2 out of 5 by from chafing wedgie. I agree with the details and workmanship of the previous reviewers. These are well made, articulated and the fabric breathes, repels etc.... I have wanted these for over ten years. I just returned from a hut trip trip, with a lot of backcountry touring, to find that these bibs like to ride up. Initially, I thought I just needed to adjust the suspenders; Arc'teryx provides ample adjustments, no luck. I extended the suspenders all the way out and still they ride up. Eventually I just undid the suspenders and folded the bib section down to my waist. I tied the suspenders around my waist so they weren't dragging on the ground. They still rode up. My day of skinning was constantly disrupted by having to undo the waist harness of my pack, pull my pants back down, re-clip my waist harness and let the pants slowly ride up again. I am 6'0 185# and I purchased the large bibs. A simple web search will provide other experiences similar to mine. As much as I have coveted these pants for 10 years, I cannot recommend them with this known issue. Hopefully it has been/will be addressed in future models.

Rated 5 out of 5 by from The only Short Large Technical Shell Bib on the market I have been looking for the tech shell bib for my husband for more than a year now. "Theta SV Bib" is the only one I found for a short stocky man. I myself own the women's version of it and I love the dropping back panel, the reinforced sit, knees and bottoms. I skied in it last season and it kept me dry trough 4 hours of unrelenting rain. The fit is true to the chart. The only thing I regret is that I could not buy them in XL with inseam 29 inches: in cold weather we normally wear thick fleece underneath the shell and that makes size L tight. Unfortunately the XL is 2 or 3 inches longer, which makes it unusable unless you have ski boots on a all times - I hate it when the pants are dragging behind you in the salty puddles. All the retailers are permanently out of stock with Short Large size, and the size we actually need is for some reason completely unavailable. Why?

Rated 5 out of 5 by from Top Quality Bib Just received my Theta SVs. Here are some important things to note: Regarding the fit, I'm finding that the leg length is more than generous while the waist is snug. I'm 5'11", 165 lbs and wearing a size Medium. As a very slender guy, I'm surprised by the fit. As of this review many special sizes are unavailable, and it's not a surprise that this includes the Large Short. Thankfully, the Medium is going to work well for me so long as I keep a trim waistline. Please keep this in mind if you tend to carry some weight in the middle. The overall shape of the pant is great. It has a fairly trim look, with enough space for layering but without the bulk. The cut is a slightly crouched shape, with a bend in the knees instead of straight legged. There is a full length zip down both legs, which can come in handy for adding or removing the pant as conditions change. Suspenders are very comfortable. As other reviewers have noted: The only two pockets, located at the top front of the bib, are certainly small. Perfect for lift cards or a compact camera, you'd be hard pressed to fit a full size smart phone in one of them. Personally, I like them and will stick to putting most items in my jacket pockets. I purchased these Theta SVs in Chipotle color and I'm happy with my choice.

Rated 5 out of 5 by from Great multi use potential Great product, I used th on a two day winter walking trip in Scotland and I was very impressed with their breath ability. I have also used them dry tooling on a very wet day in dunkeld. Great fit and hard wearing. Well designed built in gaiter. You don't need to be a ice climbing hero to get a lot out of these trousers. Worth every penny.

Rated 5 out of 5 by from Actually worth the high price Superb quality and very light weight. Performs as expected. Could use slightly larger pockets.

Rated 5 out of 5 by from bombproof These pants are incredible. I've had them now for at least 5 or 6 years. There was a honeymoon period where I was gentle with them but I have been beating on them for a few years now and they are as reliable and solid as the day I got them. Totally bombproof ProShell engineering with extra strong material sewn into the knees, behind, and ankles. I wear these pants in all sorts of conditions, all year long. With waterproof full-length zips, they are lightweight and ventilated enough to wear on a humid rainy summer day, but heavily enough designed that, with a layer underneath, they offer warmth on the coldest days on the mountain. I appreciate the way they are cut too: they are sort of slim fitting around the legs; enough so that they look good and stay out of the way (unlike so many baggy ski pants). If you lay them on their side you can see that they are cut and sewn into a sort of aggressive stance: there is just enough extra room around the knees and ankles that they look trim but feel roomy. These pants are reliable and bombproof and I can't recommend them enough. As a disclaimer, I received them as a part of the MountainTec program in order to put them to the test and review them. I have. These pants are awesome.
