Nappa leather or Napa leather is a full-grain leather, typically dyed, made from unsplit kid-, lamb- or sheep-skin by tanning with salts of chromium or aluminium sulfate, and noted for softness and durability. It is often used in high-quality leather products such as high-end furniture and vehicles.
The tanning process which produces Napa leather was invented by Emanuel Manasse in 1875 while working for the Sawyer Tanning Company in Napa, California.
