A waist or seat harness worn by kitesurfers and windsurfers to hook into the control system, transferring the pull of the kite or sail from the arms to the body's core.
A harness is essential equipment for any wind-powered board sport. Without one, you'd have to hold the full force of the sail or kite with your arms alone — exhausting after just a few minutes. Waist harnesses sit around the lower torso and are the most popular choice in kitesurfing.
They allow maximum freedom of movement and a more upright stance. Seat harnesses wrap around the waist and under the thighs like a climbing harness, providing more support and preventing the harness from riding up — preferred by beginners and for long-distance riding. In windsurfing, harnesses hook onto lines attached to the boom, letting the rider lean back and use body weight against the sail.
Proper harness fit is critical: too loose and it shifts around uncomfortably, too tight and it restricts breathing and movement.

"Switched from a seat harness to a waist harness this season — so much more freedom for unhooking and tricks."
