We love a good al fresco cocktail, but not every venue takes kindly to public drinking. If you parade around a bottle of whiskey in front of the authorities at your local park or beach, you’re sure to get busted. And while we would never condone breaking the rules, there are a few cool, clandestine ways to smuggle in drinks. In fact, these secret flasks are so brilliant, they’re worth buying just to use around the house. From a mini umbrella to the world’s greatest babydoll, these are the best clandestine flasks you can buy right now.
