I use the base layers scent loc and i love it. Make sure you follow the directions. I also get scent free showers before hunting. And of course all the clothing i use for hunting is pre washed and kept in an air tight contaner with some fresh earth wafers. My wife argued about that scent loc clothing saying there is no way it works well i proved her wrong I took a bottle of Pinesol cleaner that smells really strong with the lid offand I held it under my shirt tight up against it and you could not smell a trace of it threw the outside of the shirt! That to me is some damn good clothing!!
