Freeheart thermal insulated drinkware is 100% Made in the USA. They keep drinks cold and hot for hours, have reduced sweating, top rack dishwasher safe; microwave safe, and are BPA Free. The bottom base and walls of the tumblers are thicker than competing brands making them ~15% heavier and feel more like glass than plastic. As a result, they also insulate longer by approximately 5%. The tumblers include a sliding travel lid for drinking on the go.
