Napped leather (5)
I believe the answer is:
suede
'napped leather' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for suede that I've seen before include "Leather with a soft napped surface" , "Brushed leather" , "Undressed kidskin" , "material used in gloves" , "Leather with flesh side rubbed to velvety nap" .)
