The Rocketpack and chest control piece aren't readlily available to my knowlege. I had to make my rocketpack out of cardboard tubes and corrugated cardboad with a cardstock veneer. The backpiece was made with a sheet of 3/8" thick plywood and had added more cardstock as a veneer to hide the woodgrain.

The chest control piece was also made of cardstock that I had layered so I could create cavities to insert other parts to be able to turn the knobs. The jacket had been a lucky find at a thrift store. It wasn't totally acurrate,but it was close enough. I did have to shorten it for my Captain Proton character and had added the cuffs. The buckle is a vintage quick release for a WWII aircraft seatbelt.
