Commonly referred to by the the folks at Stanley as the "ShortStack," the Stanley 8oz Adventure Vacuum Mug is a multi-functional tool for on-the-go sipping, and eating. Out of the box, the Vacuum Mug comes with two lids: one for sipping, and one strictly for transportation (convenient carry handle included). The single portion 8oz receptacle is not only great for taking your coffee with you, but it's also an ideal way to stow something for later, like chili, soup, or curry. Take it with you, and enjoy the convenience.
