Nothing’s worse than lukewarm iced tea. Except for lukewarm, formerly hot, coffee. To find the best insulated cup, keep these factors in mind.
One issue with keeping cold drinks cold is the tendency for the cups to sweat and get condensation all over your car’s cup holder, desktop or hands. If this is a pet peeve for you, look for an insulated cup with anti-condensation design such as a vacuum sealed outer layer that helps reduce sweating.
