Odd vent placement; other than that, great.
I got these in a Large, I'm 6'1" 200 lbs with a 33" waist and they fit pretty much true to form. I have to say that the leg vent placement is a little weird -- it goes across your knees. But, other than remembering not to kneel in the snow when your vents are open, there are no other problems.
They're nothing super special, but I'm pretty satisfied.
