To fully re-activate saturated activated-carbon, you must heat it to approximately 800 °C or 1,472 °F, in a controlled atmosphere of low oxygen concentration to reduce the possibility of combustion. This is scientific fact and is even stated in the U.S. Army Corps of Engineers – Engineering and Design, Adsorption Design Guide, Design Guide No. DG1110-1-2, if you’d like to check it out for yourself. This fact is not however mentioned on any of the popular scent elimination clothing manufacturers’ websites.
....Here is something else you should consider before purchasing one of these products: activated-carbon’s adsorption effectiveness when used in an air filter application becomes greatly reduced when it is wet. So what happens when you sweat during those humid early season bow hunts? That’s right, your clothing gets wet and becomes even less effective.

A leading manufacturer of activated-carbon garments admits that no laboratory testing has been conducted to determine the effectiveness of the clothing when it is wet from hunter’s perspiration.
