LEATHER
Leather is the skin or hide of animals, cured by tanning to prevent decay and to impart flexibility and toughness. Leather has an ability to conform to your body, provide comfort, durability, and has the ability to breathe.
The term hide is used to designate the skin of larger animals (e.g., cowhide or horsehide), whereas “skin” refers to that of smaller animals (e.g., calfskin or kidskin).
The word comes from Old English lether- meaning leather (as in letherhose, leather pants).
