Redarrow.. I posted a link to Cabelas website. You can check out what they offer in the way of saftey harnesses. But, prepared for some "sticker shock".

Blueeyed.. the Gorilla EXO tech harness looks kinda like what you desribed.
I've been using the HSS for a few years now and, I have to say.. it beets the h*** out of the ones that come with your stand (although, those pain in the butt 'freebies' are still better than nothing) you can put the HSS on in a matter of seconds (even in the dark)! I have the pro series with the mesh back. The one bad thing about that one is that it tends to snag if your in a tree with rough scaley (sp) bark(which is quite noisy)! The only other negative thing I can say about it is, the leg buckles are a bit noisy (they tend to clank when you walk).
