Bra Flask

When the bra flask is empty, your bust size looks normal, but when filled with fluid, the bra flask suddenly moves you several sizes higher in bra measurements. That is because rather than just a single compartment, the bladder is split into two sections, one fitting over each breast. This gives the whole setup a more natural look. And let’s not forget about the long drinking tube attached to the bladder, through which you can secretly sip your drink directly from the bra flask without alerting any prying eyes.
