Nubuck is top-grain cattle rawhide leather that has been sanded or buffed on the grain side, or outside, to give a slight nap of short protein fibers, producing a velvet-like surface. It is resistant to wear, and may be white or coloured. Nubuck was used by cowboys as it was light and comfortable.

Nubuck is similar to suede, but its texture is finer. It differs in that suede is created from the inner side of a hide, whereas nubuck is created from the outer side of a hide, giving it more strength and thickness along with a fine grain. It is generally more expensive than suede, and must be coloured or dyed heavily to cover up the sanding and stamping process.
