I also have one and used it when I got caught out in torrential rain during a bad storm in Queensland.........rode from Rocklea to Warwick (150kls) two hours+ in non stop very heavy rain and wind, and found the jacket great. Good test for the bike as well, it was brand spanking new with zero kls on the clock and tyres that had never seen a road....scarey!!
The jacket stood up to it very well, not so the leather gloves though. I've since used it here in Tassie but never in such heavy rain, and I hope I never have to again.
