If your going to paintball can u use a mesh mask?

If you want, but paint it's going through the mesh easily! It's not recommended a mesh mask for paint ball

I say no

I know for airsoft absolutely but with paintball paint will pass through easaly and its up to the manager/refs to allow it.

Rules is that your eyes, ears, and face must be covered. It's up to the manager to allow it. But if that airsoft mesh mask you're using isn't covering your ears then they won't allow it. A helmet over your ears won't pass either.
