There's a commuter, traveler, and urban explorer in everyone. The Contigo West Loop 3.0 Vacuum-Insulated Stainless Steel Travel Mug with Easy-Clean AUTOSEAL Lid, 20 oz (591 mL), is made with every journey in mind. The ultimate in on-the-go convenience, this thermal coffee mug is leak- and spill-proof thanks to AUTOSEAL technology. Press a button to drink, then release to seal after every sip. THERMALOCK vacuum insulation keeps liquids piping hot up to 13 hours or icy cold up to 28. 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 piece, so there are no parts to misplace when you toss it on the top rack of your dishwasher. Stainless steel bodies are hand-wash only.
