That's a kitefoiling harness, they carry far more load than a wing harness.
I had the Mystic Majestic and upgraded to the Mystic Stealth, which is closer to $1000. The new harness is lighter and more compact. All the materials are water so it dries really quickly.
WIth the Stealth I use a rope loop instead of a hook. The metal hook would chip the rails of the board when it hits during a fall.
