Visited a little shop in Adelaide today checking out one piece leathers. I've noticed that some leathers manufacturers use 1.3mm leather. This guy uses 1.6-1.8mm and says that while the 1.3mm would probably be ok in a 100k off, his are track/race quality. Got armour of course and helmet rest/hunchback thingy. Price is under a grand if you go to his shop. I looked at his website and price is about $1400 so sorry for you people that don't live here. Anyway has anyone off'd in these at speed? Any opinions at all?
