Familiarity: I've put it through the wringer
Fit: True to size
I bought a pair of these a few years back mostly in response to fall hiking/climbing in the North Cascades, and I've been incredibly pleased with the fit and protection that these bibs offer. I've been out in some pretty wet conditions for long days, and these have been critical in helping to keep me comfortable in adverse conditions. I'm 6' and about 150 lbs. and the medium tall fits great. If anything, I could actually use another inch on the inseam, so I know that the regular medium would be a poor fit; I usually wear pants with 32"-34" inseam. They will easily accommodate a couple wool layers also, which helps keep options open. One thing I will note is that as durable as the material is, I did have an issue with the fabric tearing on the inside ankle of one of the pants. This was mostly just from one particularly long, wet, outing, and occurred where the thicker crampon protective layer attaches to the regular proshell layer. The tear was about 2 inches long, and was repaired by Arc 'Teryx free of charge, which I appreciate, but I was a little disappointed given how I'd only worn them about a dozen times prior to that event; I've been using them with my gaitors on the outside now, which for me will be necessary. The bibs do have a nice hook which attaches to the toe of your boot laces, and also a drawcord cinch to seal the pant cuff to your boot. There are also eyelets for connecting an instep cord, and this would be necessary to use if forgoing gators, but as I mentioned, that won't work for me ( I've had the issue of getting abrasion tears with other gore-tex pants previously, however these held up better). My wife uses a pair of OR mentor bibs, and while those are nice, I prefer the fit of these. They are super comfortable bibs and would buy them again if I ever needed to.
