Here's what I've found out from personal experience:

1: Carbon clothing helpds a little, but isn't worth the money

2: The only real way to get past a deer's nose is wash your clothes in scent free detergent. Take them straight from the drier to the plastic bags. Those clothes can't get any air in the bag. The only thing your clothes should touch is either plastic or leaves. Don't ever open that bag unless you're in the field away from your truck (due to exhaust).

3: Before the hunt get up early and shower. Use all your scent free detergent and soap. Wear clothes that you washed in your scent free detergent to wear in the truck. Then when you get to the woods, exchange those clothes with the ones in the bags.

Here's a few other things that I've found that actually help as well. If you chew, do it on stand. It helps mask your breath. Seriously. It actually helps. I chew apple skoal and i've found it helps. Those deer won't react to that smell because it's not exactly a foreign smell. It helps a little but still not completely effective.

You still MUST watch the wind. It's not a choice. You have to sit in stands that you're not going to get busted in. IF you're in a spot where deer come from every direction HUNT HIGH. Get 30 feet up that tree or you'll get busted.

If you really want to get away with it, you have to be completely anal about scent control. My brother has been using this technique for the past 4 years and hasn't gotten busted yet. Works for us and is the only thing i've ever seen, or system, that actually works. Give it a try and happy hunting.
