I don't know that brand, but I wonder if it's a humidity thing? Moist air is better at conducting heat.. I was stationed in North Carolina. I know what you mean about the humidity. It's a killer.Im in TN and the black cloth interior in my Veloster N is smoking hot in the summer with Llumar ceramic tint and a Covercraft windshield cover. Of course TN is like walking through a bowl of hot tomato soup from May-Sept.
