to observe. The EVA lasted only 46 minutes but allowed a verification of both EVA configurations of the EMU. This was the only Apollo spacewalk prior to the Apollo 11 lunar landing mission. Apollo 11 made the A7L the most iconic suit of the program. It proved to be the primary pressure suit worn by NASA astronauts for Project Apollo. Starting in 1969, the A7L suits were designed and produced by ILC Dover (a division of Playtex at the time). The A7L is an evolution of ILC's initial A5L, which won a 1965 pressure suit competition, and A6L, which introduced the integrated thermal and micrometeroid cover layer. After the deadly Apollo 1 fire, the suit was upgraded to be fire-resistant and designated A7L. On July 20, 1969, the Apollo 11 EMUs were prominent in television coverage of the first lunar landing. Also in 1969, International Latex elected to spin-off its pressure suit business to form ILC Dover. The basic design of the A7L suit was a one piece, five-layer "torso-limb" suit with convoluted joints made of synthetic and natural rubber at the shoulders, elbows, wrist, hips, ankle, and knee joints. A shoulder "cable/conduit" assembly allowed the suit's shoulder to move forward, backwards, up, or down with user movements. Quick disconnects at the neck and forearms allowed for the connection of the pressure gloves and the famous Apollo "fishbowl helmet" (adopted by NASA as it allowed an unrestricted view, as well as eliminating the need for a visor seal required in the Mercury and Gemini and Apollo Block I spacesuit helmets). A cover layer, which was designed to be fireproof after the deadly Apollo 1 fire, was attached to the pressure garment assembly and was removable for repairs and inspection. All A7L suits featured a vertical zipper from the helmet disconnect (neck ring), down the back, and around the crotch.
