I personally ever enter the woods w/o face camo (dust or paint). I don't like a net, etc, due to visibility issues. Besides, even if I am walking in from a hunt in the daylight, as long as my face is darkened, I am always in the hunt.
More than any camo clothing, I attribute my successes over the years to a hidden face. It always amazes me that the "experts" on TV wear the latest & greatest in camo patterns and scent reducing clothing, but hunt with a bright face.
I think that any type of broken pattern, plaid, or camo will work well in a hunting situation. But I'm a firm believer in getting a face dirty!
