My favorite pair of pants ever
I bought these a few years for a mix of traveling and hiking and they've turned out to be the best pair of all around pants I've ever owned. Unlike the other Kuhl pants (at least the ones I've looked at) these are lined with nylon on the inside of the pant which creates a nice smooth surface and helps keep you cool even on hot days.
Despite being 2/3 cotton, they're relatively quick drying, and I've worn them for everything from rock climbing, to light hiking, to traveling, to dinner with the parents. I've found these to be comfortable in temperatures from near freezing (if you're moving a lot) to up ~85 F (if you're just walking around town or on a light hike).
As far as durability, my first pair started getting some holes after ~2 years of medium to heavy use.
For fit, they run ~ 2" smaller (in the waist) than my normal size. They're a bit baggy, but not overly so.
