Carhart Bibs are the way to go. They are durable and covert. They even have a hammer loop that will carry a tomahawk for the upside down flipping hawk throw. They blended in well in rural Missouri anyway...
[h=3]"WE DARE YOU TO WEAR 'EM OUT" GUARANTEE[/h] If your Duluth Trading Fire Hose Work Pants ever let you down, fray, tear, rip or give out, send them back to us. No questions asked, we’ll send you a brand spankin’ new pair, and the shipping’s on us.
These have really gained a following on the 3-gun circuit and a few of us in the Pacific Northwet are using them for precision rifle training and competition. Not Multicam but definitely better made than most pants out there...and they're relatively cheap.
Their knee pads that fit into the pad sleeve on the pant are great and only run $13
