Keep an emergency stash of cash, checks, or other goodies on your person with the Patagonia Travel Belt ($30). This simple nylon belt doubles as an emergency lash strap, and features a hidden interior zippered pocket, a forged, anodized aluminum buckle, and an unassuming black or gray exterior. The only downside? You'll likely still have to take it off at the TSA screening booth due to the metal buckle — but it's a small price to pay for safety, right? Right?
