The Vespers Copper W.O.E. FlaskCopper coated stainless steel flask wrapped with American leather. At CIA, happy hours are called Vespers and to the chagrin of many security officers, alcohol can be found in every CIA Station around the globe. Vespers is a subtle nod to James Bond, who named his martini the Vesper in Casino Royale. Whether sitting around a campfire, attending a diplomatic function or building a relationship in a dark alley, a little bit of alcohol can go a long way.
