Hi mate, I have several riding suits, my leather gear is custom made as is my Cordura Jacket.
For best abrasion resistance you cannot beat leathers with good armour, for best all weather gear there is a lot to choose from in Cordura Jackets and pants.
I rarely ever wear my full Kevlar lined Jeans, I feel most safe in my Leathers, 2nd most safe in my Cordura outfit that is also very well armored, Kevlar jeans....... not so much.
Each to their own though.
My advice is buy the best quality you can afford.
