In reply to Jordangask:
The problem is that climbing helmet standards say how much protection they should offer against certain types of impacts, whilst ski helmet specs specify other types.
A ski helmet might work great as climbing helmet and/or vice versa but next to none of them have been tested under the other certification so we just don't know. I've worn my Meteor when skiing down a colouir but mainly because I had it because I had worn it climbing up earlier.
I suspect that foam climbing helmets (like the meteor) may well work much better in more skiing crashes than hybrid style helmets, because they generally offer better side impact protection, but I have no idea if it is a marginal or significant degree.
