Just my 2 cents here, don't know if it works or if it doesn,t work. I needed some new camo and wanted to get a coverall. Decided to get a scent loc one as the price was good, I figured why not it couldn't hurt. Both times that I have been out so far this year I have seen deer come from downwind and they never knew I was there. I try to practice good basic scent control as at is. So did they not catch my scent just because of the scent loc coveralls, probably not, but did it help, maybe. It looks good and feels great and I needed some new stuff as it was....
