The 2suit (alternately 2-Suit or twosuit) (abbrv. 2S) is a garment designed to facilitate intimacy in the weightless environments such as outer space, or on planets with low gravity. It has been tested in microgravity during a parabolic flight.
The 2Suit was invented by Vanna Bonta in 2006 after she experienced microgravity during a parabolic flight that she flew with the National Space Society in 2004. Bonta presented the garment design in 2006 on a panel at a New Space conference of the Space Frontier Foundation. 
The documentary described the 2Suit as "one small step for humankind colonizing the universe." The garment was presented as a utilitarian garment with multiple applications that serves the need for human intimacy and procreation by stabilizing physical proximity in microgravity environments.
The 2suit is equipped to fasten to a stable surface. The roominess within the garment is adjustable from within. It also is lined with inner harnesses that can adjust the proximity of various points of the wearer's body to the body of another 2suit wearer. A quick-disrobe function removes the garments, optionally leaving the harnesses in place for fixing to a stable surface.
Function and purpose
The function of the 2suit is to allow two or more people to remain in proximity effortlessly in weightless or microgravity environments, permitting physical intimacy and facilitating tandem or adjacent tasks.
