Can someone point me the way to a waist harness that doesn't ride up or a seat harness with a higher hook? Does it exist? I'm fed up using my mid '80s waist harness as it tends to ride up more nowadays, I've become more rotund since them trim and terrific days and more barrel shape.

I don't have a windsurfing shop locally to have a touchy feely so will need to look on the net with your recommendations.
I'm trying to avoid a seat harness if I can help it.
