Breath is probably ten times stronger than the average body odor, and we all have to breathe, so what are you gonna do about your breath ?
I also do not believe the suits work nor do I believe in any scent eliminating product. This past weekend my hunting buddy used every product available to eliminate his scent, the clothes soap, the body soap, the suit, the sprays, everything ! and he got winded immediately while I did nothing and saw deer, go figure.
