Lots of pockets, rugged construction and breathable fabric. I may only be a Weekend Warrior but I got used to the pockets on our uniforms and feel that any pants that doesn't have a lot of pockets is a poor substitute for one that does. I do occasionally conceal carry and the durability of these pants and the multitude of places to put things (the knife pocket on the right is neat, and I use the ammo pocket on the left as a great place to store my iPod nano) makes these pants my go to pants. I can definitely see buying a few more pairs as other pants wear out.
