Facility with £50 off winter sport equipment (3)
I believe the answer is:
ski
'winter sport equipment' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for ski that I've seen before include "Engage in a winter sport" , "Sliding runner" , "Go downhill fast, perhaps?" , "Take part in a winter sport" , "Go on snow runners" .)
