Best scent control I've found is a 30 degree morning with a strong thermal.

Seriously, I bet I get blown at 10x more sweating my ass off during bow season than I do when it cools off. Do scent control products work to some extent? Sure. Do they really make any difference when it's 80 degrees and your clothes are sticking to you? Nah. I use them, but I'm not fanatical.
