My first set of Syed custom leathers turns 20 years old in a few months. Despite numerous crashes and repairs, they are still wearable - and I can even still fit in them!
But, my Motoport Kevlar suit, though only 4 years old, will probably outlast them and my 'stich, put together. I think Kevlar is way more durable than leather or Cordura.
