I should clear up my statement. The nose pads adhesive melted and the pads slid off. I was able to get new one for free from Maui Jim and SuperGlue them on.
Yes the shade was closed by the sunglasses get so hot I can't put them on when I get out of work. If you look in there it is bare metal. No insulation.
I am currently looking for something I can tuck in there to help during the summer months. It's 105 today here in Sacramento.
