We’re big fans of the great outdoors and this clever gear can have you packed away without the rest of your stuff smelling like a grow house. The Deodorizer Bag is made from military-grade, activated charcoal cloth which actively absorbs odors. This active charcoal is a big step up from “smell proof” which is merely an attempt to block odors from leaking out. Because the interior charcoal cloth is active it will eventually become less effective at absorbing odors, so the “D Bag” is not intended for long term storage. Every day use should still be good for around 2 years, and longer if only used occasionally.
