this year i purchased some long john type of clothing with scent lok from cabelas and they were fairly cheap like 30 bucks for top and 30 bucks for bottom, they work let me tell u that! I put those on first then all my other warm clothing then on my outermost layer of clothing i spray it with scent a way spray good u need to spray your pack or whatever just spray everything. I was in a tree stand the other day and i was upwind from this field and this buck came right out 19 yards from me. Too bad it was a doe tag or i could of had myself a nice little 3x3
