'wrapped up' is the definition.
(I've seen this before)

'as a camper will be' is the wordplay.
'as' becomes 'in' (I've seen this in other clues).
'a camper will be' becomes 'tent' (I can't justify this - if you can you should believe this answer much more).
'in'+'tent'='INTENT'

Can you help me to learn more?

(Other definitions for intent that I've seen before include "Meaning -- determined" , "'Purpose, aim (6)'" , "'Engrossed, absorbed (6)'" , "Focused" , "Resolved; purpose" .)

I've seen this clue in the Evening Standard.
