This "Younger's" Jumpsuit was worn on screen in the season three episode titled "The Promised Planet" that first aired on the 24th January 1968. When the Robinsons nearly reach Alpha Centauri, they find a human base run by young people. The "Younger's" convince the Adults that Penny and Will aren't their children and they leave in the Jupiter-2.

The costume can be seen on screen in several scenes of the episode. Original authentic costumes from this Sci-fi classic are very rare and would take pride of place in the collection of any Lost in Space collector or Sci-fi fan. A Certificate of Authenticity is included.
