Rough to the eye, silky to the touch. The nubuck leather is made using the outer layer of the calfskin, then the part has to be sanded from the outside of the skin. Nubuck is more expensive than Suede. This is because using the external layer, only the parts without imperfections are selected. Moreover, the outer layer of calfskin is tougher than the inner part used for the suede and, therefore, logically is stronger and will last longer.
