Blue jacket material (5)

Ross

I believe the answer is:

denim

(Other definitions for denim that I've seen before include "Twill cloth" , "Hard-wearing material seen in jeans" , "dark blue material" , "Coarse durable twill-weave cotton fabric" , "Tough cotton fabric" .)

I've seen this clue in The Washington Post.
