Contigo The travel mug is made for the modern movers, shakers, commuters, travellers, and urban explorers in all of us. The ultimate in on-the-go convenience, this thermal coffee mug is a leak- and spill-proof thanks to auto seal technology. Press a button to drink and release to seal after every sip. Vacuum insulation keeps liquids piping hot up to 5 hours or icy cold up to 12. The easy-clean lid pops open completely when you’re done drinking, letting you get into all the nooks and crannies for thorough cleaning. The innovative lid is also one connected piece, so there are no parts to misplace when you toss it in the top rack of your dishwasher. Stainless steel bodies are hand-wash only.
