sheepskin-lined

5 years ago

Hi!
I've finished reading Rita Hayworth and Shawshank Redemption by Stephen King. I have highlighted 500 hundred words. Some words are not clear to me at all. Like for example “sheepskin-lined”. 
When can I use “-lined” and what does it mean?
He was usually cool, calm, and collected, but that night he was jumpy as hell, almost embarrassed, as if he was asking me to get him a load of Trojans or one of those sheepskin-lined gadgets that are supposed to ‘enhance your solitary pleasure,’ as the magazines put it. (from Rita Hayworth and Shawshank Redemption by Stephen King)
Thanks!
