Man-made material that's somewhat poorly crafted (5)
I believe the answer is:
lycra
'man-made material' is the definition.
'lycra' can be an answer for 'material' (I've seen this before). I'm unsure of the 'man-made' bit.
'somewhat poorly crafted' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'LYCRA' is hidden in the letters of 'poorly crafted'.
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for lycra that I've seen before include "Material for exercise wear" , "Fabric used in tight-fitting cycling wear" , "Elasticated synthetic material" , "Sports clothing fabric" , "skin-tight garments" .)
