Standard visors may disfigure if left in a vehicle window on a hot day when the vehicle is not in operation. We recommend taking the visor out of the window and storing it in the door pocket, the pouch on the back of the front seat, or between the front seat and center console.
Custom visors will not disfigure in extreme heat. They can be left on the window even when vehicle is not in operation.
Both the standard and custom visors are produced in a size that provides ample protection from the sun. Just as you would with the front windshield (factory installed) visor, never use SideVisor in an unsafe manner.
