I have a pair of Maui Jims with a clamshell case. The case fits very well in the forward portion of driver's door storage area. I have got to put them in their case everytime or I'll scratch them. I have never liked the visor clips myself. Today I just left them on the dash and grabbed them when I got back in the X.
