Smoke is how I mask my scent. When I think of smoke and hunting it's not always about smoking cigs. I won't claim it works 100% of the time, but I've had numerous deer downwind of me after "smoking up" my clothes and observed their reactions. They will usually throw their head up, scent check the air a few times, cautiously look around, and then go right back to whatever they were doing.

So, does a human that has been sitting by a campfire smell more like a human or a campfire?? From my experience I say campfire

Does a deer associate campfire or leaves/brush burning with danger? From my experience I say no

I still wash my clothes in scent/UV brightener free detergents, but I haven't bought into the other scent free hype. For me, I picked up a Bee smoker and use it to �smoke up� before hunting.
