I am a big fan of Propper Lightweight Tactical pants and shorts.  They dry quickly when wet, are truely light weight, and fit me perfectly.  These shorts have plenty of pockets to use while hiking and are really  great to wear just as casual shorts.  I get a lot of compliments on the pants and the shorts when I am wearing them as casual wear.  They are strong, well made, and most importantly, are worth every penny I paid for them.
