Abstract: The present invention according to a first preferred embodiment comprises a cylindrical drinking vessel having a pair of integrally formed circumfrential grooves and a pair of vertically oriented parallel handle support braces on its outer surface. A carabiner, or rope connection latched oval or D-shaped ring, fits between the handle support braces in a position to straddle the pair of circumfrential grooves. A pair of flexible bands are releasably fastened through the carabiner and around the vessel in the circumfrential grooves to secure the carabiner as a handle to the drinking vessel and thus form a cup. In a second preferred embodiment of the invention, the cylindrical vessel is integrally formed with a pair of handle supports to which are assembled a hinged latch so as to emulate the operation of a carabiner. According to a third preferred embodiment, the carabiner is formed separately and fixedly attached to the side of the drinking vessel, for example, by welding.
