While it’s at-heart nothing more than a two-sectioned, soft-sided bag, the Flight 001 Spacepak (Clothes Pak version) has a simple, potentially-useful trick: pack all your clothes in the ‘Clean’ side at the start of your trip, moving them to the ‘Dirty’ side as they begin to reek of smoke, sweat, and bacon. Sure, you could do this with a couple of large resealable plastic bags, but you wouldn’t get all the handy, silk-screened lettering.
