Whether Scent-Lok works or not doesn't matter. Too many less expensive ways to fool a deer's nose for me to plunk down that kind of cash. I agree with all the posts about scent-free soap, clothes washed in baking soda, and using home-made scent-killer spray. After washing, spray all your clothes down with scent, allow to dry outside, store in scent-free bags, and do not put them on until you get out of the truck to hunt. Yeah, it sucks changing clothes outside when temps are below freezing, but so what. I also spray a camo bandana with scent killer and wear it over my mouth. You can take scent-free to any extreme, but any little thing you do will help some. Most importantly, hunt the wind! My $.02
