You gotta get Owala! It’s steel and for this price it is a steal. It keeps the cold for 24 Hours My family uses these every day and I want to pass these along to you. These are brand new with the tags on them. These fit in my drink holders in my Ford Edge, My Ford F150, and my Nissan Rogue. Keep your drink cold and enjoy life. Check out my listing also for the Triton as well.
