I have a hard time finding pants that fit (34x36). Most are too short and since I weight train, too tight in the seat/thighs. My work pants of choice are loose fit Carhartt jeansand these prAna (large) fit just like the Carhartts. They are very comfortable and the Lycra makes it easy to make that widestem, backstep or highstep while climbing. They do not interfere with my harness, are lightweight, and cool. They are not waterproof (no uncoated nylon is) but they dry quickly which is an awesome feature in the backcountry. They also take up less room in a pack than cotton pants. I find the unusual fly ok but I like the pocket arrangement and zipper side pockets. I will not be purchasing cotton climbing/hiking pants again anytime soon.
