Aspen 20 oz Glass Tumbler

“I'm very picky about what I drink my coffee out of. Metal is a no-I can taste it! Glass is my preference but doesn't stay cold and sweats. This is my perfect to go cup. Glass on the inside, insulated metal outside. I can make an iced coffee before work and it stays cold, not watered down and no sweating 4 hours later. Easy to clean in the dishwasher.”
