Collapsing Helmet-The miracle of modern technology, modern skin suits have an emergency, collapsible helmet built into the neck of the suit.  If the wearer doesn’t have time or can’t get to a proper helmet in time, the helmet deploys and keeps the pony able to breathe until they can get into a proper helmet.  Which should be soon, as the collapsible helmet is very uncomfortable (like wearing a too-tight gas mask).
