THIS WAS A GREAT POST!!! it really is amazing with these creatures if you think about it...one little flinch and boom gone...I know this is going to sound stupid but i came up with a awesome idea 2 years ago for the mist that comes from our breath in the winter months...not only did i use it so im not spotted but have also used it to prevent fogging on my glasses. Find a buck grunt call...take out the mechanics inside that make the noise or just use the tube...depending on your gear find a way to make it comfortable in your mask but inside!! i have the tube go around the side of my face to wear it will not interfere with my mask and OMG its amazing!! NO FOG OR MIST THAT COMES OUT!!! i also came up with this cause i was sick and all i could do was breathe out of my mouth because my nose was so stuffed lol. if you dont want to dismantle a deer call go to your local auto parts store and pick up a thing of spark plug wire covers or and wire covers...very light, different sizes, and different lengths. my dad bought a black on and has it run from his mask to the front of his jack and faces the tube out his jacket and still no fog because the fog is already being created in the tube but because of the length it evaporates because of the length of the tube. Just make sure to clean it after every hunt!! i hope this helps everyone!!!
