Abstract: A wearable sombrero-style hat with a refillable reservoir is disclosed. The sombrero-style, or type, hat has a generally conical crown with an opening at the top of the conical crown. The opening allows the use of a reservoir that is adapted for insertion through the opening in the conical crown. The reservoir also includes an upper end with a fill neck that has a cantilevered collar or protrusion that extend from the fill neck in a generally radial manner. The collar or protrusions engages the edge of the edge of the opening at the top of the generally conical crown to support the fill neck at or near the top of the conical crown, while the lower end and outlet of the reservoir are positioned below the fill neck, and thus allow the connection of a dispensing tube to the outlet of the reservoir, and thus allow the user to drink from the reservoir through the dispensing tube.
