RE: scent lock or scent block clothes
It looks like a mixed bag on the subject.
I am a bow hunter and here's what works for me: I place my hunting clothes in a Kolpin Gear Bag on the back of my ATV and pin 2 dirt scent wafers on the inside of the bag. When I head in the woods I usually break off a pine branch and rub it on my trousers and shirt. I then drop it on the ground and scrub my boots on it. This method has never failed me and I don't care which way the wind is blowing.
For added protection, I also hang dirt wafers in my P/U just in case I should use it instead of the ATV.
I'm surprised that none of you mentioned the wafers.
Oh yes, I also wash my clothes with odorless detergent and frequently scrub the bottom of my boots.
