Apparently, Rock Bottom has a Basement Tumblers

A modern take on an old tumbler classic, the insulated tumbler combines the build and functionality of the original but with a sleeker form factor that is easier to tote around. Constructed out of ultra durable double-wall stainless steel that is vacuum insulated, your drink will remain a consistent temperature 2x longer than your typical glass or plastic containers.
