I think the rings prevent it from getting hot which is why I believe they are hollow for circulation. NF even if you feel right on the body in between the rings it isn't that hot at all so what is making it that way...circulation is my only guess. I of course may be wrong and we will know tomorrow when clicker gets the email answer. I also think Joe's mockup it looks naked so I guess you guys should go ahead if you can take the rings off when we find out if they have use or not and put a naked woman on your INH. You know you want to.
