SunShader 4.0 is now in stock. With our newly designed, slimline, soft rubber clips that sit on the very edge of your screen, none of your valuable screen space is lost. Plus, new internal materials ensure your SunShader retains its shape in even hotter weather. Sizing: It is important to measure your laptop WIDTH (not the diagonal screen size) and use the Size Chart Image on this page to get the correct size for your laptop. SunShader is the original, patented laptop sun shade, heat shield, splash hood and privacy screen. It protects your battery from being damaged by overheating, and allows you to see your screen clearly in direct sunlight.
