Arc'teryx gave the answer with the Men's Theta SV Bib. What was the question, you ask? Alpine professionals asked for a pant that would deliver protection from the elements in four seasons of wet, nasty weather. Ask and ye shall receive! Look towards this bib if you need a tough, full-coverage pant for expedition mountaineering, serious backcountry skiing, or alpine climbing.
The Theta SV Bib is built with waterproof breathable Gore-Tex Pro fabric laminated to the N80p-X nylon, sealing out any adverse weather while being a supple and notably soft to the touch. Reinforced paneling of N15-p-X shell fabric in the knees and butt is burly enough for any adventure, and the reinforced Keptrotec instep patch can take a nick from a crampon or two. The high-rise bib is an alpine classic; a streamlined profile with an integrated elastic waist to keep warmth in and snow and drafts out, and a full drop-seat option that does not require removing the suspenders and is compatible with harnesses make it a no-brainer. The Cordura powder cuff seals out the snow, and the full separating two-way zippers let you vent as needed or remove the bib over boots with ease. Now, the only question alpinists are asking is, "What mountain should we conquer?" You're on your own there.
The Arc'teryx Theta SV Bib features N80p-X GORE-TEX that offers exceptional durability and full weather protection in a supple, notably soft touch textile. Reinforcement fabric is used in the knees, lower leg and seat areas of high wear areas. Full separating side zippers give a drop seat option without the need to remove suspenders. Powder cuffs fit over boots with lace hooks to secure position. Hems have cord cinch. Elastic waist is integrated for comfort and clean finish. Stash pockets on the front bib hold small items. Rugged, resourceful, reliable.
The Arc'teryx Theta SV bib pants thrive in harsh weather conditions where protection is key. They are crafted with robust Gore-Tex® fabric for high-performance protection and durability.

These are the first pair of bibs I've owned, and so far I'm pretty pleased. They are lightweight, seem very durable, have nice articulation in the knees. I like the fit for the most part - slim, but not overly tight. A great fit for touring when you don't need extra material hanging around, such as when you are using crampons.
I do feel the pants are a little tight in the crotch, although not bad. Even with the suspenders fully extended, still feeling some pull in the groin while skinning. I went with the Medium, which fits great everywhere else (33 in waist, 5'11" 170 lbs). And I have tried a large, which doesn't fit that well throughout my lower half. So it seems to me this particular pant isn't quite tailored to my body, although not a big deal.
My only gripe, although with a shell pant like this I shouldn't expect too many features, is not having a significant pocket for holding things like keys, wallet, etc when I am hitting up grocery store or gas station before heading up canyon. The pockets provided are fairly shallow and are best suited to a small snack or a multi tool, something of that size.

These bibs are thin, light and durable. I have owned these for a season now and they are my go to bib for most days. I like to layer and that is why I prefer these shells. They have absolutely no insulation, pretty much gore tex saran wrap for your lower half. I have climbed a few times in them but would probably still prefer my soft shell for ice.
The built in gaters are weak and should have been made with a little more quality for Arc'teryx. The vents are ok but i still prefer my old Patagonia Patrol pant vents that came with mesh inside the vent.
I would recommend these to someone who wants a high quality shell bib.
I ordered these based on my previous experience with Arc'Teryx. I own several other Arc'Teryx products that I love and use routinely.
The Good- These bibs are extremely light weight and well constructed, the fit is athletic, and they look pretty slick.
The Bad- The pockets... I knew this going in, but it really doesn't hit home until you put them on for the first time. More pockets, deeper pockets, or simply no pockets at all would have made more sense to me.
The bigger issue was one that's mentioned in Cory Akin's review. The suspender length is not enough. Extended all the way out, the Theta SV's still tugged in the groin and went right up the backside every time I bent over. Not fun in my living room, much less fun in the backcountry. I'm 6', 185lbs, size large.
A solid product with some major design flaws. Ultimately, I returned mine and will keep searching.
