X.One® screen protectors are not made from tempered glass. It is made out of polymer based material imported from Japan which is more durable in terms of anti-shock feature compared to tempered glass.
However, there is only one tempered glass series in X.One® which is the Gorilla Series which is made only for curved screen devices. Although the Gorilla Series does provide an anti-shock feature but the protector still cracks once your device fall onto the ground.
