This mug is powered by SNAPSEAL Technology, which provides on-the-go, leak-proof confidence when in the closed position.
To drink, simply push the lever up, then push it down again to seal the lid. Its one-handed operation is ideal for when you're on the go. Thanks to THERMALOCK double-wall, vacuum insulation, your drinks will stay hot for up to 6 hours and cold for up to 12 hours. The one-piece lid means there are no loose parts to misplace.
