Snagged these bibs at the beginning of the season and now have about 45 days in them. I couldn't be happier.
The fit - I am a 6'1 lanky build, and I ordered a medium. Coming from a baggier (more spacious) bib, I am happy with the form fit. Even though it is more trim, I don't feel that I lost any range of motion or ability. Overall, they really nailed the fit for skinnier folks.
Durability - I have used these both for resort days hot lapping lifts, and back country days. I have not seen signs of wear through any of the joint areas (knees, hips, backside). Additionally the weather facing pockets and zippers seem durable and can handle an aggressive pull without breaking.
Could do better - the kangaroo pocket isn't as awesome as I would like. It doesn't have enough room and I also noticed that I am cautious when opening and closing both chest zippers compared to the weather facing zippers (as if I am going to rip the piece off from the zipper); a larger pocket with a more durable zipper would be $$$$.
Final Thoughts - easy. If you to want chase powder out-of-bounds, or rip hot laps in-bounds, then buy these top-notch bibs.
