my buddy was telling me about a covering for hunting blind windows that he called see-through shoot-through. he said it would stop the cold wind from blowing in and will not fog up. i have checked around all the local shops and no one has any thing like this and have never heard of such a thing. ?? is my buddy been pulling my chain or is there such a product out there. if so what is it's proper name and where can i get it. it gets a little cool in my northern michingan blind in late november.
