A:Answer Indeed, it is wearable. It is a bona fide helmet. It is adjustable as well and it fits my big head. I don't think there are many heads it won't fit either, lol. I can also see out of it quite well. I know what you mean though. Almost every costume you see, comes with a mask that's open in the back. Or, it won't even show the back of the person's head, and not specify if the mask is just a face mask, or a whole head helmet like you're looking for... So just to be clear again. Yes, this is a whole head helmet that should fit kids as well as adults.
