Designed for coffee, tea, or whiskey, this insulated tumbler pairs the strength of 316 surgical-grade stainless steel with an ultra-thin silicon dioxide lining for a clean, glass-like taste. The smooth, hydrophobic interior resists flavor transfer, while the durable, shatter-resistant construction is corrosion-resistant, hypoallergenic, lead-free, and recyclable. Double-wall vacuum insulation keeps drinks hot for up to 12 hours or cold for up to 24 hours, depending on the lid style.
