We incorporated our triple-action odor control system. The external fabric layer traps in odors, and there are two internal layers of our ACTIVATED CARBON FIBER (ACF) fabric, which absorbs odors. The outer rip-stop nylon layer is perforated in order to provide airflow to the ACF fabric layer behind it. Once the DISCREET-O-MATIC ACF fabric fills up with absorbed odor compounds it can be recharged by heating with a blow dryer, or in a clothes dryer.
