On hot days, iced drinks poured in ordinary cups quickly turn to an unpalatable dilution, and the vessel itself becomes annoyingly slippery with condensation. Likewise, on cold days, hot drinks turn unpleasantly lukewarm in typical mugs. Enough is enough. The 22-oz. Matte Black Double-Wall insulated tumbler can hold ice for 24 hours, even during the dog days of summer; it also keeps coffee, tea and cocoa piping hot for hours during winter’s chill. Its ergonomic, narrow-to-wide design allows it to fit easily in most cup holders, and its lid fits securely, preventing spills. Essential for outdoor workers or anyone who prefers their cold drinks cold and hot drinks hot.
