> A zipper breaking as you flee from danger may make the difference in survival. In an apocalyptic scenario, zippers are way too annoying to fix and replace. Rip out your zippers and replace them with cordage through metal grommets, or with button flys. Army duffels use overlapping folds of material with metal grommets and one giant metal clasp. Roll-top bags just need rolling and can be tied closed with cord.
