This is one of the strangest things I remember from my childhood. Dad was a fireman at the airport and he had one of these at home in the attic. An asbestos suit. I suppose they used them at one point when fighting fires. It was in a box and only taken out a few times, I remember my older brother wore it one year at Halloween. The suit was not for sale on ebay, just the ad and there was a link to this video about the suit. Strangely enough, when my house burned we found this in the rubble and it was mostly burned.
Edited to add a photo I found of my younger brother wearing the suit.
