The bottoms are kinda tight, especially around the ankles. Its kinda a good thing tho because it seems to stop that nasty habit of your underlayer folding up in your boot and being a pain in the ass. The tops they make are also really really really good. I highly reccommend mine that I bought last month, its loose, light and keeps heat in like a motherfucker when you have a layer over it. I've used it for running, and it so nice. So nice. If its cold, I put a t-shirt over it and it keeps me really really warm, but even in august I could run with it, as alone, it wicks moisture away so fast that it cools you, and keeps even me, a honestly pretty sweaty guy, dry. Amazing stuff, well worth the $40 I paid in the store for it. It shows up around here every so often, snag some when you see it.
And also, I'm sad that other ski companies that make outerwear and softgoods normally dont ever reach into this market. It would be cool to have some more choice and style when it came to it (HH has taken it a step by doing something cool with their sleeves, but more is needed!)
