Bag from excursion, reportedly (6)
I believe the answer is:
sachet
'bag' is the definition.
(I know that sachet is a type of bag)
'excursion reportedly' is the wordplay.
'excursion' becomes 'sashay' (I've seen this before).
'reportedly' indicates a 'sounds like' (homophone) clue.
'sashay' sounds like 'SACHET'.
'from' is the link.
(Other definitions for sachet that I've seen before include "Package" , "'Small soft bag, for perfumed powder say (6)'" , "'Small soft packet, of pot-pourri perhaps (6)'" , "Cheats (anag) -- small porous bag" , "Scent bag - shampoo envelope" .)
