I was looking at a new pair of Richa textile trousers today,all the EU approved safety tags etc,on reading a bit further it turns out the only bit that's certified is the removable knee armour,there is a disclaimer on the rest of the fabric,so it's got to be leather trousers with armour for me,I currently use John Doe Kevlar jeans,they are a German brand,full Kevlar to the ankle,with well placed knee armour,I'd imagine they'd give better protection from road rash than just textile,hope I never find out though.
