We have to say, this 16 oz. matte black RTIC Travel Mug is our favorite. It is our flagship product and perfect for all our loyal supporters out there. The slim design lets the mug fit nicely into most cup holders.  Your drink will stay hot up to 6 hours (or cold up to 24 hours.)

Details: kitchen grade stainless steel, double-wall, vacuum-insulated, screw on flip-top splash-proof lid, no sweat exterior, air-tight seal, easy grip base.
