These pants are mostly great, but with a few issues.
First, the great:
The color. I got the chartreuse, and I get TONS of compliments on them. My boyfriend also loves that they make me very easy to spot on the slopes.
The fit. I am 5'9", 140 lbs, wear 6/8 pants, and the medium is a nice fit they are even long enough, which is hard to find. I always wear something under them because I tend to get cold easily and can just open the vents if I'm too warm.
The styling. The 2 front zippered pockets looks really cool, and these pants are quite flattering.
The waterproofing. They are guaranteed to be waterproof, and they are. I have worn them in storms, in powder, and in slush, and I have always remained dry.
The venting. I can open them up and stay quite cool on warm spring days.
The extras. The left pocket has a small internal velcro pocket that is the perfect size for stashing some cash, a credit card, and driver's license. The right pocket has an attached glove hook.
Then, the issues:
The waist adjustment. The specs on this site are incorrect. These pants do not have belt loops, and the only source of adjustment is a pull tab on the waist connector.
The waist connector. There is some black webbing that leads to a plastic "belt" connector. This does not always stay fastened.
The connectors. These pants feature a zipper along the back which allows you to connect the zipper of a Burton jacket. This is a really solid interface. However, if you don't have a jacket with the zipper, there are no side connectors to attach a more conventional snow skirt to. I got really frustrated when the Burton AK Baker jacket did not feature this zipper, even though Burton claims all of their AK jackets do.
Overall, I love these pants even though they're not perfect. Although I have several other pairs of snowboarding pants, I have worn nothing but these since they arrived. As long as the issues mentioned above are things you can live with, I recommend them.
