What Are Team USA's Gymnastics Leotards Made Of?

Many gymnasts wonder what fabrics are used to make Team USA's competition leotards.

These custom-made leotards are made from a shiny fabric called mystique.

Mystique takes traditional spandex fabric and layers it with thin, flexible foil and holograms.

This process gives the leotard a special 4-way stretch elasticity that makes it both aerodynamic and breathable.
