The suit Neil Armstrong wore when stepping onto the moon was made using cutting edge technology of that time. A good part of that technology and suit construction came from a bra manufacturer in Dover, Delaware. The suit had to live up to a whole range of specifications, a very important one being that it be capable of containing the pressure necessary to support life i.e. 3.75 pounds per square inch of pure oxygen.

Faced with that problem, the manufacturers of the suit, International Latex Corporation turned to a division of the company that manufactured Playtex bras and girdles. Using their knowledge of rubber garments, the engineers there managed to put together a suit that met the above requirements. They also invented a bellowslike joint called a convolute and made of neoprene re-inforced with nylon tricot that allowed astronauts to move their joints at the shoulders, elbows, knees, hips and ankles. Steel aircraft cables were used through the suit to absorb forces and help the suit maintain its shape under pressure.
