As the weather gets cooler, I which up my iced coffee for hot coffee, and I am CONSTANTLY looking for mugs that keep coffee hot. I came across the Corkcicle Tumbler, that claims to keep beverages hot for 3 hours or cold for 9. I am here to tell you that at least on the hot side of things, this tumbler is LEGIT. I still had hot coffee at 10 am and I poured it at home around 7:20 am. Its a little pricey, but it works so well, I am buying another immediately.
I’m buying the 16 oz size for my coffee, and a 24 oz size for my ice water at work. And with so many cool colors, they look great too!
