This stylish, stainless steel barware will give any beverage a little extra flair, but it is practical as well as pretty. Vacuum insulation keeps drinks cold for hours, and prevents condensation from forming on the sides. The press-in lid has a silicone gasket to protect your drink from splashes and debris, whether you are traveling or just relaxing outside. The 19-ounce mug is completely BPA free and should be washed by hand, though the lid is dishwasher safe. Do not microwave.
