I remember when I was wondering if I should buy a surplus chemical suit. I talked to my sister, who is a chemist, and she told me that activated charcoal is activated charcoal, no matter what form it is. It is a filter and it will work. So I spent the $20 bucks and I couldn't be more pleased. I don't wear it during shotgun season, because I don't think that scent control is that important then, but I do wear it a lot during bow season, although not all of the time. It is bulky and uncomfortable, and in NY when it is cold out, I would rather wear layers of clothes that keep me warm. I do have to say though, I have yet to be scented in the woods when I was wearing it. I think I'm going to buy another one that fits me better too. Take care
