I own several army charcoal filled chemical warfare two piece suits (Get them from Gary-Sportsmans Guide). Wear shorts under it early in the season, more when its cooler weather. Don't wash em'. I just leave them on the wash line on a rainy day, toss them in the dryer. I've used all sorts of camo including a long sleeve ASAT as my outer garment on a warm Texas afternoon. I can honestly say I have not been busted, not even once, while wearing the chem suits. Bowhunting since 1963, used WWII camo back then.
