Extremely good, more than once, about British article in winter sports equipment (8)
I believe the answer is:
toboggan
'article in winter sports equipment' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'extremely good more than once about british' is the wordplay.
I cannot really see how this works, but
'good' could be 'g' (abbreviation) and 'g' is found within the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is present in the answer.
'british' could be 'b' (abbreviation e.g. in 'BBC') and 'b' is located in the answer.
'extremely' could be 'too' (eg extremely expensive could mean too expensive) and 'too' is located in the leftover letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for toboggan that I've seen before include "Narrow sled for snow" , "Light sledge for sliding downhill" , "Long light sledge for snow" , "Sled with boards curved up in front" , "Slider" .)
