A coupler is coupled to the mounting panel so the coupler may be operationally coupled to the vehicle sun visor so the mounting panel is operationally coupled to the vehicle sun visor. A primary panel is operationally coupled to the mounting panel so the primary panel is positionable between an extended position and a stored position. The primary panel is selectively positioned in the extended position to block sunlight for a user. A secondary panel is operationally coupled to the primary panel so the secondary panel is positionable between an extended position and a stored position. The secondary panel is selectively positioned in the extended position to block sunlight for the user.
