It's all what you have confidence in I guess. Kinda like fishing lures. The one you use works becuase that is what you are throwing.
Myself, the only commerical stuff I will buy is the regular green soap by Scent Killer (the liquid body soap), and any of the scent free anti-persprents. I also use a good scent free /UV brightner free laundry detergent, on my hunting clothes. This year I am trying the Dead Down Wind Laundry stuff.
Thats it.
I keep my clothes in a rubber made tub with chunks of cedar sapling, cut into 10-12" lenths, and scuff the bark up.
Then I can do what those fancy Carbon Suites claim! (forget the wind & hunt) but I don't I still mind the wind. lol
