It appears that some of the rear cover options for the Moto X 2016 (which may also be known as the Moto Z) have appeared online. These apparent "MotoMod" style modifications offer covers with a number of different designs and materials for Motorola's next phone. Materials for these covers seem to include leather and wood.
