STM 15 inch Laptop Backpack (Black)

Omne trium perfectum. It’s said that good things come in threes, so it’s no surprise you’ll discover plenty of great stuff in our aptly named Trilogy backpack. From a trio of storage compartments (two main ones, plus a full-size front pocket) to a triad of additional pockets (internal mesh, external drop, overflow stash) and much, much, much more. Designed to fit your lifestyle, we consider it a triumph of functionality and style. The Bag has "REVERSE COIL ZIPPERS" To "show one’s teeth" indicates a demonstration of strength or power. But in the case of our reverse coil zippers, not showing the teeth is what makes this closure so tough. The zippers on our Stories bags position the slider on the flatter side and feature a fabric covering over the teeth that helps to keep out dirt and moisture (the kind of stuff that has no purpose getting into your bag in the first place). The Bag is madeup of "WATER REPELLANT FABRIC" that Protect your stuff while you protect the planet. Stories is crafted from environmentally-friendly, free of perfluorooctanoic acid DWR C6 plus two coatings of polyurethane. That means wetness has to really, really work overtime if it’s gonna get inside your bag (past the outer water-repellant material, then the double layer of PU, followed by the inner lining that’s treated with yet another coating of PU).
