Top-grain leather, (the most common type used in high-end leather products) is the second-highest quality. The “split” layer has been separated away, making it thinner and more pliable than full-grain. Its surface has been sanded, and a finish coat added to the surface which results in a colder, plastic feel with less breathability. It will not develop a natural patina. It is typically less expensive and has greater resistance to stains than full-grain leather so long as the finish remains unbroken.
