Hit the slopes and almost lose control (3)
I believe the answer is:
ski
'hit the slopes' is the definition.
(I've seen this in another clue)
'almost lose control' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'lose control' becomes 'skid' (I've seen this in another clue).
'skid' with its last letter taken off is 'SKI'.
'and' acts as a link.
(Other definitions for ski that I've seen before include "Runner for use on snow" , "Descend fast" , "the end for many Russians" , "Winter sport accessory" , "Glide ove snow" .)
