Fellows hanging on to a cowboy's legs? (5)
I believe the answer is:
chaps
'fellows' is the definition.
(both can mean men)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for chaps that I've seen before include "Blokes" , "Cowboy leggings" , "Men; leather trousers" , "Guy's" , "People" .)
