There's nothing worse than ripping your gear, unless you're talking jeans in the 90's, in which case -- dude, awesome jeans! For ultra-durable accessories that won't expose your boxers, check out Ragged Edge.
Run by a maritimely-minded Virginian mother/daughter team who originally just wanted a bag for their smelly sailing clothes, Ragged's a collection of insanely tough carrying cases (ranging from card sleeves to large duffels) made from rip-proof materials like Pentex, PET-X, Carbon fiber, and Kevlar Aramid, which "doesn't have the same following as Carbon Fiber", probably 'cause of bad head shots. Large-scale stowers include backpacks like a just-released carbon fiber joint with triple step zig zag stitching and a wrap-around zipper for "easy opening from your right shoulder" (suck it, lefties), "gear bags" like the 22'' x 10'' x 11'' Traveler made from PET-X sailcloth ("not as fancy, but durable to the core"), and a kevlar briefcase that's "been known to stop bullets" and has "3 pockets for the little things", which'll be perfect for clearing out your desk when your manager overhears you bragging about gunfire. Smaller satchels include a specifically-proportioned carbon fiber iPad bag with magnetic flap closure, all manner of wallets (from bifolds, to trifolds, to a minimalist clear plastic/orange kevlar ID sleeve), and document holders such as a bright orange, double-pocketed PET Folder, also a Japanese profession vital to keeping Tokyo's subways efficient.
Continuing their Mac-ish descent, they'll also soon be dropping equally tactical sleeves to hold iPhones and iPods, which'll keep 'em intact, even if your brain is what got acid-washed.
