Levi's work great, or the double front carhartt jeans are probably awesome, but theyre pretty damn expensive....This might sounds really lame... But the best pair I ever used were from aeropostle (I think thats how it's spelled) They were having some before school sale, and I got them for 13 dollars. Now I know they dont sound like they would be good because theyre from a hoity toity "fashion" store, but they lasted me a whole year on the road w/o another pair of pants, they just ripped actually, andI got new ones cause theyre doing that sale again. The thing I liked the most about them, was they feel awesome and they had some elastic material that made them stretchy, so even when I got nicks in them it didnt become a giant gaping hole.
