Query: Does not keep beverage hot

We have two of these travel mugs as they came in a set. I personally like my beverage hot-not lukewarm. I sip on my beverage over the course of a couple of hours & with these mugs, it only stays hot for about 30 minutes(& I live in a warm climate-no snow). The mugs are durable as far as cleaning. They seem to seal well(haven't had any accidental spills in the car) & they come in a nice array of bright colors. But, overall, I would have to say that not keeping the beverage hot is why I have to only give this mug 2 stars.
