Save your money!!!! If you want to use scent blocker buy the spray for $10. I would also suggest going to your hunting area and picking up limbs, leaves, etc.. and putting them in panty house. Then put the panty hose in a sealable rubbermade bucket and put your clothes in it with it. This is much more natural and keeps them from smelling you.

However, the most important part is playing the wind. If you are sitting in your treestand don't forget to bring a pee bottle to pee in so you don't leave your scent beneath your tree.
