Perhaps it’s barely taken off (3)
I believe the answer is:
Here is my best explanation:
'barely taken off' is the definition.
I can't judge whether this definition defines the answer.
'perhaps it's' is the wordplay.
'perhaps' becomes 'k' (I can't explain this - if you can you should believe this answer much more).
'it's' becomes 'it' (I've seen this in other clues).
(Other definitions for kit that I've seen before include "Stuff", "Set - uniform - gear", "Set of parts; clothing", "Set of articles or tools", "Outfit", "Gear", "Young stoat", "Supplies", "Young cat" and "Young beaver".)
