I just use really cheap camo I bought from walmart in the early season, and then switch to my nicer, more heavy duty camo when it starts to get cold. Whether scent control actually works or not, its too deeply rooted into my pre-hunt ritual to just stop using it. My camo/undergarments are always washed in scent free detergent and stored in a scent free container, I bathe in scent free soap and water and dry off with a scent free towel, I use scent free arm and hammer deodorant, I spray everything that comes into the woods with me in scent free spray, my boots and climber stand always stay outside on the porch, and I always brush my teeth with arm and hammer baking soda tooth paste, and then I eat an apple. To change any of that routine before a hunt would just be bad luck.
I wear camo and spray down my clothes I never can play the wind in my neck of the woods as soon as I think its out of one direction it swirls around on me partly because I hunt river bottoms between the bluffs it seems to always change throughout my hunts.
scent away earth scent smells just like freshly turned dirt. if you scrape the ground in the woods down to the dirt , it smells exactly the same.. also cedar branches rubbed all over your clothes makes you smell like a cedar tree which are abundant in our area.
One of the best tools a deer has to help it survive in the woods would be it's nose and ears. Don't take that for granted. If you can control your scent, DO IT! What can you lose?
