I can understnd your need to go "light" in Hawaii. And let me assure you, it gets HOT with the sunroof. Thank the MINI gods my A/C runs incredibly well. The screens do very little good when the sun is over head. Also, I hate wearing hats but may consider it because of the sunlight in the eyes. I'm hoping one of the after market companies comes up with a solid clip on cover for the interior of the sun roof. MINI should make those silly screens a solid material.
