Description from the vendor website:

The Pack Out Bag is a convenient solution for carrying full poop bags (read: poop) hands-free between drop points. A water-resistant shell fabric and waterproof lining work in tandem with a waterproof zipper for easy-to-clean odor containment. Includes an adjustable belt to carry it around the waist. Or, directly attach it to a pack or your waist with the integrated clip.

The Pack Out Bag makes it a little easier for all of us to doo-doo our part to keep our trails clean.
