As far as I am concerned the more the marrier. Depending on the weather I usually ware what I have under my camo's in the truck. When I get there I spray myself down. Then I lay my outfit out on the ground and begin to spray that down. When I have everything the way I want it I put it on. If the weather is hot and I am sweating like a pig I hit myself again. When the weather cools down I dont throw any more on because I feel that I have covered all the bases.
