leatherstocking (n.)

Old English leðer (only in compounds) "tanned or otherwise dressed hide or skin of an animal," from Proto-Germanic *lethran (source also of Old Norse leðr, Old Frisian lether, Old Saxon lethar, Middle Dutch, Dutch leder, Old High German ledar, German Leder), from PIE *letro- "leather" (source also of Old Irish lethar, Welsh lledr, Breton lezr). As an adjective from early 14c.; it acquired a secondary sense of "sado-masochistic" 1980s, having achieved that status in homosexual jargon in the 1970s.

In commercial and popular usage leather does not include skins dressed with the hair or fur on: such skins are usually distinguished by compounding the word skin with the name of the animal from which they are taken: as sealskin, bearskin, otter skin, etc. In the untanned state skins valued for their fur, hair, or wool and destined to be tawed and dressed for furriers' and analogous uses, are called pelts or peltry. [Century Dictionary, 1900]

"close-fitting garment covering the foot and lower leg," 1580s, from stock "leg covering, stocking" (late 15c.), from Old English stocu "sleeve," related to Old English stocc "trunk, log" (see stock (n.1)). Probably so called because of a fancied resemblance of legs to tree trunks, or a reference to the punishing stocks. Cognates include Old Norse stuka, Old High German stuhha, from the same Proto-Germanic source. Restriction to women's hose is 20c. As a receptacle for Christmas presents, attested from 1853; hence stocking stuffer first recorded 1945. Stocking-feet "without shoes" is from 1802.
