No,

But I Did spend up to over 5-6 hours at s time in a borrowed harness a few weeks ago. I also satyed at a Holiday Inn Express last night. Ok, not really, it was the Hyatt.

It was during the 2010 GT300 www.gt300.com,
it was a full version of one of the magic marine harness'.

It was very comfy and gave me no problems. Not bad for a borrowed harness.
