I love these thermal tumblers for when I'm at the beach or on the boat. It really does work to keep your wine cool. This one from Nestally comes in a variety of colors, and I chose navy blue. In addition to the tumbler, it comes with a metal straw, a tool for cleaning the straw, the cap which can be closed to keep your beverage intact, and a cleaning tool for the tumbler. I should note that it clearly states on the bottom that it is dishwasher safe and I have washed mine that way several times.Most importantly, this really works to keep your beverage cool. I poured 8 oz of chilled water into the tumbler, and did the same in a plastic cup. I let them both sit outside for a while on a pleasant day, about 74 degrees and very sunny. The table it was on was warm but not hot.When I checked on them after nearly an hour, the difference in temperature was clear. The tumbler was 55 degrees, but the plastic cup was almost 68 degrees. That is what I call significant!The Nestally tumbler delivers on keeping your drink cool, and it does it in a durable and attractive package that is dishwasher safe.
