The "I Am Not a Paper Cup" coffee mug features a hollow cavity nestled around its inner perimeter. This insulating barrier helps maintain the temperature of the liquid inside while keeping the outer surface comfortable and cool to the touch.

Basically, once the barista hands over that venti double extra hot caramel macchiato frappuccino (with non-fat milk), it's going to maintain that 147.5F temperature without burning your hands.
