What are some good, thin, light, quick-drying pants that you use outdoors? I'm looking to be using these on a 2 month Europe trip, so lots of pockets would be a plus.

My main problem with these kinds of pants is that they pockets are almost always super shallow and have a vertical opening, meaning they dump all your shit out when you sit down. I hate it.

Anybody know of ones that won't leave you looking for your fallen items if you decide to slouch in a chair?
