I am a true believer in the sprays. I only use Hunter Speciality sent-a-way spray. I order it by the Gal. befor bow season every year. the wife and I use it and there powder for the boots and hats with a passion.
We spray our cloths and let dry and when we get out of the truck in the woods , I spray her and she sprays me.I will not go with out it.

you have to first make sure you and your cloths are clean and sent free as much as you can.I don't say it covers everything but every little bit helps.
I rattle a lot in B/P season and have deer downwind all the time and they don't smell me for the most part.

I do believe!!!
