Fur hat and coat from Russia sank at sea (9)
I believe the answer is:
astrakhan
'fur' is the definition.
(astrakhan is a kind of fur)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for astrakhan that I've seen before include "Hark, Santa is in Russian wool" , "Fleece from Central Asia" , "Hark Satan (anag.)" , "Fur - city on Volga" , "Russian sheep's wool" .)
