Know before you buy
Yes, the Mega Mug is designed with a 2.9-inch base diameter specifically to fit most standard cup holders, despite its large 40oz capacity.
The lid is designed for everyday use and includes a secure slider, but it is not 100% leak-proof. It is best to keep the mug upright to prevent spills.
While the mug is technically dishwasher safe, we recommend handwashing to preserve the integrity of the finish and insulation over the long term.
The mug uses a combination of double-walled vacuum sealing and copper plating to minimize heat transfer, allowing it to keep drinks cold for over 24 hours or hot for over 9 hours.
Yes, the mug comes with a BPA-free plastic straw that features a flexible silicone tip for added comfort while sipping.
No, the triple-insulated construction is designed to be condensation-free, so the exterior will remain dry regardless of the temperature of your drink.
