The Osprey Ultralight Zip Organizer is a toiletry bag for keeping everything together. Once you arrive at camp or hostel, open up the Ultralight Zip Organizer and hang it from the clip loop so you have quick access to all your toiletries. A mesh pocket allows damp items to get some air when not in use. The see-through section is see-through. Sorry, it doesn't take a rocket scientist to figure out that one. That section is removable though, so you can lighten your load a touch. Don't forget to brush your teeth before leaving the bathroom, you probably hid your toothbrush in one of the other zippered pockets. Once you're done, close it up and tuck it neatly into your pack.
