The 2suit (alternately 2-Suit or twosuit) is a garment designed to facilitate low-effort sex in the weightless environments such as outer space, or on planets with low gravity.[13] The flight garment, invented by American novelist Vanna Bonta,[2] was one of the subjects of Sex in Space, a 2008 History Channel television documentary about the biological and emotional implications of human migration and reproduction beyond Earth.[13][14][15] The 2suit sparked international discussions in news and political debates as a metaphor for human colonization of space.[16][17]
