Know before you buy
Yes, the base is designed to fit most standard vehicle cup holders, despite its large 40 oz. capacity.
The mug features a spill-resistant slider lid. While it is excellent for preventing splashes and minor spills, it is not 100% leak-proof if the mug is tipped over completely.
Yes, the entire mug, including the lid and straw, is dishwasher safe, making it easy to keep clean after daily use.
The copper-plated inner lining provides an extra layer of thermal insulation, which helps the vacuum-sealed walls maintain your beverage's temperature for over 24 hours for cold drinks and 9 hours for hot ones.
No, the double-wall vacuum insulation ensures the exterior remains condensation-free, so you won't have to worry about water rings on your desk or a slippery grip.
The included flexi-straw is made from BPA-free, durable plastic designed for regular use. It is flexible enough to be comfortable but sturdy enough to withstand daily cleaning.
