Almost miss out winter sports equipment (3)
I believe the answer is:
ski
'winter sports equipment' is the definition.
(I've seen this before)
'almost miss' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'miss' becomes 'skip' (to skip something is to miss it out).
'skip' with its last letter taken off is 'SKI'.
'out' acts as a link.
(Other definitions for ski that I've seen before include "Take part in a winter sport" , "the end for many Russians" , "Participate in winter sport" , "Winter sport equipment" , "Piece of sports equipment" .)
