I have one of those tight stretchy ones. One day I went out and it was hot, too hot to wear my Swanee wool, so I left it in the car. Wearing a leather Arvis hat, white and red plaid wool shirt and khaki brown pants, at least I had my face mask and my Nifty seat. I was still hunting anyway and would probably not get a shot. When I stopped, parked my butt on the Nifty seat, I ripped off that face crusher to hydrate and eat my apple, a small 8 pointer came walking up. Red and white shirt, white beard, I did not even have my hat on and my sweaty bald head was probably reflecting like a car mirror. That little buck walked with in 20 feet of me. I thought, 'you poor blind fellow', I thought he was blind and considered putting him out of his misery. He looked right at me like I was not there. Then another hunter fully camoed and straight down wind of him and me walked across an alfalfa field about 200 yards away. The little eight pointer flopped to the ground about 15 feet from me and did not take his eyes off the other hunter until he was out of sight. He then got up and browsed his way around the bend and out of sight. I have no clue why he could not see me, sitting there with my back against a baseball bat sized tree. I still hate that face crusher mask, I still have it in my pocket and I still take it off as soon as I can.
