(Other definitions for angora that I've seen before include "Fabric from animal hair" , "Breed of goat with silky hair" , "Yarn made from hair of goats or rabbits" , "Long-haired cat, goat, or rabbit" , "Name of goat at 12 Across" .)
'wool' is the definition.
(I know that fleece is a type of wool)
This is the entire clue.
(Other definitions for fleece that I've seen before include "Gull" , "warm garment" , "Warm coat; swindle" , "Wool coat" , "Cheat" .)
