We cant offer na answer other than that its not rated for it, so officially no.
In a ski helmet i would want something that has ear protection and more protection at the back of the helmet.
Saying this i have a meteor and its a great climbing helmet, i have also used it for a bit of paddling and i would use it on a bike.
Ski helmets can be cheap from aldi/tk maxi/ sport pursuit so why not get 2 helmets, an elios and a ski helmet if price is an issue. Would be about the same as a meteor.
