The Simple Modern insulated tumblers are made of high-quality food-grade stainless steel. Whether you are drinking water, beer or even coffee, this tumbler will not retain the taste or smell of any liquid.
This tumbler has a double-walled exterior with a vacuum between the walls. This means your drink has no medium for the heat or cold to transfer through.
Stay hydrated at the office, while camping, on road trips, hiking, cycling, golfing, shopping and so much more!
