Aerial silk (also known as aerial contortion, aerial ribbons, aerial silks, aerial tissues, fabric, ribbon, or tissu, depending on regional preference) is a type of performance in which one or more artists perform aerial acrobatics while suspended by a special fabric. The performer climbs the suspended fabric without the use of safety lines, and rely only on their training and skill to ensure safety. The performer uses the fabric to wrap, suspend, fall, swing, and spiral their body into and out of various positions. Aerial silks may be used to fly through the air, striking poses and figures while flying. Routines are an exciting display of athleticism, coordination and flexibility.
