BlenderBottle GoStak | Black 9″ Container

The innovative design of the BlenderBottle GoStak allows athletes to carry multiple energy drinks, snacks, supplements, or other items inside a single, existing BlenderBottle Classic container. The GoStak starter set includes four separate jars of incrementally larger capacity, which can then be stacked and locked into place with a simple twist. Each jar seals tightly and is highly durable, so theres no risk of leaks or one drink diluting another.
