The surface of both the Ripper and Hammer feature a hexagonal pattern that has been has printed at a 1200 dpi resolution. The design inside each of the hexagons has been printed in a random dot pattern to eliminate cursor fade and jitter. The back of the Ripper consists of a foam type rubber glued to a printed cloth sheet. The foam type rubber adds a level of padding and prevents the mat from slipping during use. The X-Trac Ripper can also be easily rolled up for transport and thrown into a bag. The back of the X-Trac Hammer uses an ultra thin rubber compound called the Sure Grip II which prevents it from slipping while maintaining a thin profile.
