An attachable sun visor system includes a sun visor extension assembly including a sun shade panel, an extendable rod having a first-end, a second-end, and a mounting member. The sun shade panel is configured to attach to a rod of a stationary sun visor in a vehicle and swivel from being adjacent to the stationary sun visor during non-use to being perpendicular to the stationary sun visor during an in-use condition to provide an effective shade area in combination with the stationary sun visor.
