Sargas 320 is made of a durable microfiber cloth material with slightly more friction than coated mouse pads. The special microfiber surface counteracts data loss and improves the sensor tracking performance. The Sargas 320 was built with our in-house S.Q.A.T technology which tests the data loss of the surface, many months of testing has been carried out to ensure that this cloth pad has an extremely low data loss. The underside is made of natural rubber offering a firm grip irrespective of the surface under the mouse pad or extensive movements. The wide tracking area ensures for long sweeping movements without interruption.
