White coveralls..
I bought some extra large white painters coveralls some yrs. back. I used some kids felt tip pens to draw some camo patterns on the coveralls. I then washed them in hot water with some bleach to tone down the felt tip camo pattern.These have served me well over the yrs. and the price was very resonable. I have yet to wear them out or be cold in them due to the fract that I can wear layers under them. For my head and hands I use white fleece gloves and a white knit face mask. I also cover my rifle or shotgun, whatever I am using, with white tube socks for a quick snow pattern. All works well enuf to take generations of ducks, geese and 'yotes. Good luck!
