I've been wearing the 5.11 Taclite pants for years now pretty much every day. I like the lightweight fabric for daily wear, the front pockets are deep enough to to carry a 3" J frame S&W, the belt loops fit a 1 1/2" gun belt, and plenty of pockets for knives, flashlights, magazines, etc. They have given me good wear life - I've only worn out the first pair I bought but that took about 6 years of constant wear and I could have stretched that out some more.

Some complain that they look too "tactical" and will telegraph that you may be a gun person but there are an awful lot of cargo pants out there so I don't think that this is a real problem.

They make several styles but the Taclite's normally go for $50.
