Embodiments of fluid containers are described that include a multi-chambered fluid bladder and a sealing mechanism for selectively sealing off different chambers from each other for independent use, such as for two different kinds of fluids, or opening to fluidly connect different chambers to each other to form larger chambers for a common fluid. Embodiments can further include independent fill ports and outlet ports for each chamber. The sealing mechanism can comprise a clip or latch that is configured to clamp the fluid passageway in the bladder closed. Some embodiments can include a removable handle that attaches to the bladder and includes the sealing mechanism.
