Picture it: you're going to the beach. You've got a ton of shit to lug there—chairs, coolers, umbrellas, towels, books/magazines that you won't read, etc. You've got a ton of beer and food, but you want to bring something else to whet your whistle. Maybe some tequila, for instance. Maybe some FIREBALLLLLLLLLL if you really want to have a shitshow on your hands. But you don't want to add to the weight by bringing a glass bottle. Introducing the answer to this alcohol-on-the-go conundrum: the Incognito Flask ($7, Vapur). Lightweight and durable, this guy holds up to 10 oz of liquid (that's 10 shots for those of you playing along at home) and collapses down to nothing when empty. Things are about to get rowdy.
