Designed by gamers for gamers (and office work, too), the XL is 2 to 3 millimeters thick with stitched edges that prevent fraying and peeling. Along with a smooth, low-friction cloth surface, featuring the company logo in the lower righthand corner, it has a nonslip rubber base to hold everything in place. Plus, it’s machine washable and waterproof, so you can keep it in your desk setup for years to come.
