I should edit my thoughts.I dont think they matter enough to justify the cost. Never wore it,often dont even practice the wind direction rules.Shot 179 buck and many more does in my life time with bow , slug gun,rifle,pistol flintlock and inlines. I hunt close quarters all shots under 50 yards.I do use natural smells. In the early bow season often wear sneakers. I hunt from the ground and do wear cheap wallmart camo jogging pants and shirt and jacket. All the equipment you buy does not make up for a good spot you scouted and spent months watching and 100' s of hours sitting waiting in a season. I know guys that even shave there heads tp prevent the hair from smelling.Gee I have a full long white beard and shoulder length hair. I eat italian food on stand or any left over from the night before.Pee on the ground and pop soda cans. Need the soda to wash down the popcorn and pepperoni. Love pop corn between pepperoni slices. Not joking seiously. I dont drive a truck to the huntin spot but a 84 honda,when I was younger use to take my harley with a little trailer. I watch some of the other hunters. And it takes them 30 minutes just to get all their equipment on there bodies you would think their going to the amazon for 6 months. Kinda funny. Then they walk by me on the way out and scratch their heads while they view my deer. I heard one guy say 2 years ago to his buddy. What in the hay is that crazy old varmit doing we aint??? I reached around and grabbed some pizza and ask if they would like a piece? LOL
