I got a pair for hunting (free), and I agree with the velcro comment. My other issues are that the crotch is cut weird (read different enough from the BDUs that it can be felt in the fit), and the back pockets aren't deep enough. My billfold sits too high which means it puts my butt cheek to sleep when I sit on it too long.
Totally concur with the Navy camouflage. There isn't any time in the Navy where you want to blend in with the water, unless you are a SEAL, and you won't catch those guys wearing those. Then with all the individual augmentation orders to send sailors out to do Army jobs the first thing you have to do is issue sailors a bunch of new uniforms.
