I like the Mountain Hardwear Canyon and Mesa pants. The Mesa is very similar, and made of the same fabric, but with a more khaki look. I like the new Mesa, which doesn't have any big cargo pockets, something last year's Mesa and many other hiking pants had.
I don't often wear shorts, and I don't like convertibles. I did buy a pair of shorts for this summer- the MH Canyon short. Same material and sizing, with an imported pocket configuration compared to my Canyon pants from 2007-08.
I don't bring heavy rain pants. I often don't bring any, but when I do, I just bring DriDucks, which are very light and cheap.
