Full-grain leather keeps the outermost layer of the hide intact, including its natural marks. It is the strongest grade, and it is the only one that develops a genuine patina.
Top-grain has that surface lightly sanded and refinished to even out blemishes. It is more uniform, slightly thinner, and more resistant to staining — but it will never age the same way.
Nappa describes a finish rather than a grade: a soft, full-grain leather (usually lamb or goat) tanned to a supple hand. It is what makes a jacket feel expensive the moment you put it on.
By hand, a good hide has a slight give and springs back when pressed. If it feels like plastic film over foam, you are holding a bonded or heavily coated leather.
