Zippers and TSA-approved locks are about as good at securing your suitcase as leaving your doors unlocked and using The Club to protect your car. They only keep honest people honest. Well, to paraphrase Doc Brown, "Where we're going, we don't need zippers".
Trunkster, a totally zipperless suitcase, packs a digital scale, internal GPS, and a USB charging station -- all in one lightweight case. Travelers Jesse Potash and Gaston Blanchet got tired of hauling around luggage that made accessing their belongings difficult, so they designed the Trunkster. A sliding rolltop door replaces the need for a zipper allowing quick access to whatever’s inside. And the airplane-grade aluminum and polycarbonate design makes the suitcase look pretty slick.
