Hobo evades clothing that's blown in the wind (4)
I believe the answer is:
oboe
'that's blown in the wind' is the definition.
(musical instrument, part of the woodwind section)
'hobo evades clothing' is the wordplay.
'clothing' says the answer is hidden in the clue (the solution is covered or clothed by the clue).
'OBOE' can be found hidden inside 'hobo evades'.
(Other definitions for oboe that I've seen before include "issuer of notes" , "Reed instrument" , "Slender double-reed instrument" , "Player" , "Double-reed wind instrument" .)
