There is no way scent killler can work. When we walk in the woods every time we take a step the air in our boots go poof, poof, poof. It is letting air out and with it comes scent spores scent bombs. And when ya walk and move your arms, scent escapes from your arm pits and does the same. Then your hair does it too. The wind carries it till it sticks on branches and grass where you just walked. The only way to stop it is to put your feet in a plastic bag and tie them tight. This might work a bit but damp feet are cold feet. I wish I had 1/10 of 1% of the profits the scent spray compaines made.
