RealTree AP for turkey hunting and for Deer during Archery Season. But I believe that camo is strictly the choice (to wear or not to wear) of the hunter.
For those of us that are older... I can remember when there wasn't any "camo" and natural colored clothing were the items of choice. And scent blocker was gotten by hanging your clothes near the wood fire.
Seriously though, camo isnt really important when some states mandate blaze orange hats & vests!
