When there is an overlap of seasons, I wear a thin orange vest and my insulated hat is reversible. Once I get in the stand I wrap the vest around the tree and reverse my hat to camo. I usually don't wear the orange at all walking in for a morning hunt because I walk in total darkness and hunting is illegal then, so I am walking in the dark and not hunting. If some fool shoots me withmy flashlight on,orange wouldn't save me anyway. 100 square inches on head and 250 square inches on back and chest combined, I think.
