People forget you have to breathe. Every deer in the woods can tell we are predators when they are down wind of our breath.

Now there is something to be said for losing the odor that rubs up against brush or foliage. Toss some corn stalks in your hunting tub...you're clothes will smell pretty, too (if you like the smell of corn).

If you don't have a hunting tub for your hunting clothes, that's step #1.

Something to think about: They have drug sniffing dogs that can find minute traces of drugs hidden in sealed coffee cans. Coyotes and many other critters have as good or superior noses to domestic dogs........

The only way for these suits to work would be with a space helmet and air supply and a reservoir for the air which you breathe out.
