Well,not like they advertise. Im very funny about my scent and at any given time in the archery season i have 2 layers of reactivated scent lok or scent blocker on. Scent lok head net also, with rubber boots. Then i spray down with scent killer. My clothes goes on at the tree and comes off at the truck. Also bathe in scent killer wash before going out. You can try to do everything right, but when the winds BAD, its BAD! Got nailed the last Friday of the season by a buck coming into a scrape, and taken all precautions, this time of year there nose is going non-stop, more so than earlier, looking for estrous does and all. Just my .02
