This insulated also doubles as a bowl to use along side your favorite instant water boiler while out backpacking. This specific tumbler has a press in lid with a sliding closure. The design/words have been etched in and will not wear off. You didn't hear it from us but this tumbler also doubles as a great place to keep your wine cold while sitting around your campfire.
