Sometime you should smell the inside of your hunting hat. I keep all my archery equipment in a air tight box and still use scent elimination spray but I always sprayed the outside of the clothes once i got them on in the field. Then one day I decided to check the inside of the hat. Our hair leaves a greasy smell that I'm sure was allowing the deer to wind me. Now, if your bald, I'm not sure what your hat smells like
