Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying, foot-launched glider aircraft with no rigid primary structure. The pilot sits in a harness suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.
The paraglider consists of a canopy (the actual "wing") constructed of rip-stop nylon from which the pilot is suspended by sturdy Kevlar lines called risers, and a harness. In addition, the brake cords provide speed and directional control and carabineers are used to connect the risers and the harness together.
