Like anything, If it makes you feel better, than good on ya! Comfort and mind set is essential to the confidence you need to drop an animal.I bought a Scent Loc suit a couple years ago. Made no difference to me. I had deer under me before, and after. Can't say it helped. Can't say it hurt. I'm one of those folks who don't perspire much. Limits my scent Irecon. I wash the suit with my regular hunting cloths these day (nice camo). Maybe somebody can prove the stuff scientifically, I don't know. Sure wish somebody could invent something to get those deer out prior to dark andalilviate my sittingin my stand a couple hours after dark. Missed many dinners, and deer, because of that dark thing.
