This has been a highly debated topic for many years. There are many people that swear by it. I have seen many use it and get busted. The idea behind it is that the carbon absorbs your odor. The problem is that it can only absorb so much before it has to be reactivated. This is where the problem is. To reactivate the carbon in the suit you would have to burn it in a fire as your dryer is not hot enough. I am sure that brand new, it will work for a short time though.
