From the ITV website:
Our kiting harness was designed for Paragliding and Powered Paragliding pilots who want to ground handle their wings and sharpen their skills. Compact in size, well built, robust and easy to use, it is the ideal companion to carry with you anywhere.
Too windy to fly?, practice your kiting skills – one hour spent handling your wing on the ground is worth one hour in the air!
Beware!, this harness is not certified and not made to fly with – KITING ONLY!
