It is common for the organizers of endurance sports to provide aid stations along the route where participants may receive water to prevent dehydration. To reduce waste at these events, organizers encourage ‘cupless’ races that requiring participants to carry their own vessels. The present invention comprises a hat with a visor, such as a baseball style cap, with a collapsible drinking vessel integrated into the visor. During the course of the race, a runner may encounter a water stop and require a vessel to contain the liquid for immediate consumption. At such time the runner can simply remove their hat and configure the vessel to the open position to receive the liquid. Post-consumption the vessel is configured back to the closed position and becomes seamlessly integrated into the visor with no negative effects upon the runner.
