The Demogorgon is made from an inflatable yard sprinkler made by Big Mouth. We took it abd added an airtight zipper and a clear window in the middle of the mouth so that you can see out of the suit. The suit is a sealed single layer design. This type of design has no fans to keep it inflated so it is dead silent and if someone hugs you, it doesn't deflate. You can even have someone lay on top of it and it will support their weight. Breathing is through a snorkel that comes out in the back of the head.
