In reply to Mattia:
Sorry for the delayed reply.
Yes, it was just their standard full body harness. This seemed to load far more evenly than the Mad Rock, which Penny had found pretty unbearable/uncomfortable whilst being lowered off.
At the time we were half tempted to get a small group test put together, as this info was likely to be useful for plenty of others, but didn't due to the fact that it would have really needed a couple of other harnesses to make it truly comprehensive (and at the time I think Penny just wanted to go climbing!). That said, maybe it is something we should revisit if anyone else out there has experiences of other full body harnesses.
Maybe one to bear in mind if you hear of any feedback from elsewhere.
