The FAA’s 2011 U.S. Commercial Space Transportation Developments and Concepts: Vehicles, Technologies, and Spaceports report has a section that looks at commercial spacesuits being developed by American companies.
One of these companies, ILC Dover, has been building spacesuits for NASA for decades, producing the suits worn on the moon by Apollo astronauts and space shuttle astronauts. The David Clark Company has been around since 1941, producing pressure suits for Chuck Yeager, Gemini astronauts, and the space shuttle program. The third company, Orbital Outfitters, is a newcomer that is designing pressure suits for XCOR’s Lynx suborbital vehicle.
