If you want to watch some decent reviews of suits and the features they offer, take a look at http://www.sportbiketrackgear.com/motorcycle-race-suit-shopping-guide - Yes, I know they are from the US and not local.
I went through all of their vids posted and made my decision and then ordered locally
Most suits have individual reviews posted as well http://www.sportbiketrackgear.com/leather-race-suits
thats was my first step.. unfortunately can't find any place with rstaichi stuff in stock(or even available on order) for example.. those videos are really helpful
