The custom-designed mouse pad covers 100% of the Arena surface and adheres firmly to the desk thanks to special materials. The Arena mouse pad features a microfiber surface that is water-repellent and machine washable. The edges of the mouse pad are stitched, and the pad has a thickness of 5 mm to maximize user comfort. Finally, the entire mouse pad weighs an impressive seven and a half pounds (3.4 kg), which, along with the non-slip bottom, means it is resistant to accidental movements on the surface.
