Hey! Ally Love here. As Contigos Chief Hydration Officer, Im thrilled to help you confidently take your drink anywhere with the West Loop 3.0 made for the commuter, traveler, and urban hustler in all of us. Leak- and spill-proof thanks to AUTOSEAL technology, this travel mug keeps your beverage safe whether its stored in your work bag, gym bag, tote bag, or car cup holder. Press a button to drink, then release to seal after every sip. THERMALOCK vacuum insulation keeps liquids piping hot up to 11 hours or icy cold up to 24. The Easy-Clean Lid pops open completely when youre done drinking, opening up all the nooks and crannies for thorough cleaning. The lid is also one piece, so there are no parts to misplace when you toss it on the top rack of your dishwasher. Hope you love it as much as I do!
