I often use fresh earth dryer sheets while drying my clothes, after washing them in scent free soap. At some point I started putting these dryer sheets in the plastic tubs that I store my hunting clothes in. This seems to work very will. Anytime I pull my clothes out of the box they reek of fresh earth.
I'm too tight to be buying a bunch of scent loc, which I don't believe in. So this is a good and cheap alternative. I like it so much I even toss one in my backpack to help cover the smell of my food and other gear. Its not fail proof (nothing is) but if you do this and bath in scent free soap (as I do) you will find yourself spooking fewer game and harvesting more bucks/bulls/coyotes.
Try it out this season and see if it works for you.
