The best are Kangaroo hide leathers which can be expensive but they are a lot lighter than cow hide and as a one peace give the best protection.
You can get two peace in kangaroo hide and for non track use they are easier than a one piece for touring purpose.
There are many types from top line; Arlen Ness, Dainese.Texport,Spyke or Crowtree/BKS made to measure, on the cheaper front JTS do a good line of suits with good armour for not much money.
It comes down to money with most people.....how much do you value your hide WN.
