Stealth Black Wingsuit
That wing suit. Only one was ever made. Whereabouts unknown.
It was reputedly the fastest wing suit ever made and had the slowest falling speed. So good was the aerodynamics, it was capable of incredible lift over several seconds. Enough lift to make a landing (without the hassle of cardboard boxes - eat your heart out Gary Connelly).
Well, you can't get your hands on the wing suit, but the next best thing is the t-shirt. If you have to ask whether it comes in any other colour, other than black that is, you need to go out and see the movies.
