We can't all afford a bulletproof suit, so for the cost-conscious business traveler, consider accessorizing with the $899 MTS Multi-Threat Shield. It looks like an ordinary attache case, but quickly unfolds into a three-foot tall Kevlar shield that can block bullets, knives, and even physical attacks. Granted, it weighs 8 pounds, which might be a bit heavier than your average bag, and it won't actually hold your laptop. But it protects against handguns, shotguns, and submachine guns. With an optional armor plate slotted into a front pocket, it can even block a high-powered rifle.
