This is a custom build and will take several days to make. Made with sturdy vinyl strips and bolted together with actual chicago screws. This piece remains light without having to use EVA foam. Not as light as eva foam but much sturdier. We make the straight jacket as well (not included in this listing) If you get the straight jacket from us it will include straps to keep it attahed to the jacket. If you are not purchasing the straight jacket then you will need to figure out how to keep it stable on the head. Let me know if you have any questions.
