Garments for space travel? (5)
I believe the answer is:
capes
'garments' is the definition.
(cape is a kind of garment)
'space travel?' is the wordplay.
'travel?' indicates an anagram (I've seen 'travelling' mean this).
'space' with letters rearranged gives 'CAPES'.
'for' is the link.
(Other definitions for capes that I've seen before include "Short cloaks" , "Cloaks or headlands" , "may be worn" , "Sleeveless cloaks - promontories" , "Space for cloaks" .)
