Croatian designed wet weather gear (8)
I believe the answer is:
raincoat
'wet weather gear' is the definition.
(I've seen this before)
'croatian designed' is the wordplay.
'designed' is an anagram indicator (designed with the letters).
'croatian' with letters rearranged gives 'RAINCOAT'.
(Other definitions for raincoat that I've seen before include "Actor in a (anag) - wet weather garment" , "Water-resistant outer garment" , "Wet weather gear" , "Catriona (anag.)" , "Mackintosh" .)
