Your is safe with us. The Cleaner carbon-filter duffle is fully lined in activated carbon to keep any revealing odors trapped inside. With dual zippers, feel confident your goodies are securely zipped up and concealed from others! You can lock the secondary interior zipper with any padlock (not included). This sleek design features a durable, water-resistant polyester exterior, a built-in key lock, and a logo for your privacy. How does activated (or treated) carbon work? Activated carbon particles are modified to absorb odor molecules. When the odor molecules come into contact with the treated carbon, they are trapped within the pores of the carbon until the product is reactivated. To reactivate your duffle bag, cycle it in a dryer on low for 10 minutes.
