In 35 years of bowhunting......I've never used scent killing products available from the hunting industry. It's been my experience no matter what you wear or put on your body, the moment you hike a few steps your body starts producing smell........and a wild animal's ability to sense it is second to none.
I simply try and keep as clean as I can so I can stand myself when I crawl into the sleeping bag at night. Part of that is using Mitchum unscented deodorant (solid).......it works very well.
In my opinion, the most important part to being successful (especially with a bow and arrow) is simply being downwind and understanding thermals. No matter how bad one smells, if they're downwind from their prey they will remain undetected by sense of smell. Good luck this year!
