I bought it thinking it would be similar to all ski helmets. It's not. It has very limited foam on the inside. It's like 80% shell. Will it save my dome from lacerations?
Will it help save you from lacerations? The area that it covers, yes.
But the reason for wearing a helmet isn't for cuts, it's to protect you from impacts. More padding is better when it comes to protecting you from impact. So yes it will work, but no, not very well.
