Did you know that the Czech Republic produces the best quality material for parachutes? This material is exceptional in that it is very light in weight and extremely high in strength and logically does not blow. If it fails the buoyancy tests, it is discarded. If you can't make a parachute out of it, you can make a jacket out of it, and not just any jacket. The Parachute jacket is extra super breathable thanks to the absence of a liner.
