When astronauts began walking in space, their suits had to be further altered to give more mobility and comfort while providing more protection from micrometeorites and accidental rips and tears.
The Gemini space suits were airtight casings enclosed by a layer of woven fishnet fabric that prevented ballooning when the suit was pressurized.
A layer of felt and seven layers of insulation lay under a nylon outer covering for protection against temperature changes.
Life support was provided by the spacecraft through a tube connected to the midsection of the suit.
The Gemini space suits were worn by astronauts for launch, in-flight activities, including EVAs, and landings.
The space suit was designed by NASA based on the X-15 high-altitude pressure suit, and has been used by the U.S. Air Force on U-2 and SR-71 Blackbird high-altitude flights and even on the Space Shuttle.
Gemini spacesuits were designed and manufactured by the David Clark Company in Worcester, Massachusetts.
