BUT - The tough fabric pretty much ground through and ripped apart in multiple places. Luckily, Gen managed to roll around and keep his unprotected parts mostly off the ground. The woven fabric suits are cooler, more flexible and potentially smell better and can be kept cleaner with less work, but if you fall at high speed, slide on and abrade the fabric significantly, If it were mine, I'd seriously look at replacing the jacket or replacing tha damaged areas on the suit or jacket. The second or third time you slide on the damaged area, it is more likely to grind through, losing garment integrity. Just so you know, I'd be happy to wear a new fabric suit or jacket, though.
Leather is heavier, hotter and less flexible - but more durable over the years and crashes.
Even when it's hot. There's a certain amount of comfort knowing that the leather wears through slowly and linearly and if a decent set of thicker leather, doesn't usually rip. When I was racing, a guy named Bob Agness would hand select hides for suitability for different parts of the suit. I had 2 sets of leathers. In hindsight, I suppose that, if I saw a guy that I raced with start preparing for a crash before the race even started, I would at lest mentally note that, too.
