2suit. The 2suit (alternately 2-Suit or twosuit) (abbrv. 2S) is a garment designed to facilitate sex in weightless environments. It has been tested in microgravity during a parabolic flight.

History

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.

In 2008, the first 2Suit was manufactured and tested  by a History Channel documentary for the television series The Universe. The episode premiered on December 3, 2008.

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.

Design

The 2suit is a flight suit with a large front flap that can be opened and attached to another 2suit via Velcro strips.

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.

References in popular culture
Cracked.com listed the 2Suit as one of "seven real suits that will soon make the world a cooler place." 

The 2Suit has been mentioned in travel and exploration magazines as part of articles on subject like the "400 mile high club."

The 2Suit was discussed as fashion in WIRED and Discovery Magazine, among other media.

The 2Suit has been the subject of songs, including the Valentine's Days album titled 2Suit, by Binary Bits, and in the Anti-Gravity Love EP track Sex Suit by Irish band Fred and Bob
