The idea here is based off of collapsible cardboard that’s used in military airdrops. The design would not be long lasting but more a consumable product that could be purchased in a vending machine and used while traveling.
It would even be possible to use light biodegradable plastics to make it longer lasting.
This need to be replaced. I don't know who to credit for it, but it is not original artwork.
On the bright side: when you're dealing with a helmet that's already been made, you know feasibility will be off the charts. ;)
