Most ski / snowboard helmets are pretty similar and have the features / advantages you detailed. I have a couple Carreras myself that weren`t certified for bicycling when I bought them simply because winter bicycling wasn`t as common as it is today. (Notice I said `common` and not `popular`).

Anyway - one comment regarding the sweating issue. Its a reality in skiing too and so the common strategy is to buy a slightly larger helmet and wear a balaclava under it. That not only offers the option of full face protection on seriously cold days - its a lot easier to wash a balaclava than to wash a helmet liner.

So I have a few balaclavas and wash them on a very regular basis.
