How does a suit's design become dated?
Well, when I came back and started racing again in 1999, I had my old Dainese leathers and wore 'em for a year. I had a get off on a 600 in an endurance race wearing those leathers at the chicane at TWS. I'd crashed 'em before in the old days at up to 100 mph. I thought they were great leathers regardless of the road rash I got THROUGH them.
Not even a hole in the leathers and they burned up my forearms in a get off at T3 TWS once. I've crashed in most of the corners at TWS at least once.
Well, I got these new Teknics. They have hard armor EVERYwhere and soft back armor and soft armor in many locations where hard armor isn't necessary. They actually have KNEE PUCKS. I was still duck taping my knees with the old Daineses.
And, they were soft padded throughout. I have crashed in 'em at 80 mph right at the apex of T2 at TWS, a FAST corner, was at full lean and it seized. It tore some of the stitching on the back, the bike rode on top of me all the way off the track and I didn't flip, just laid out on my back. I could feel the friction heat off the back of 'em through my Knox back brace!
Yet, I was unscratched, not even a bruise. I don't recall being hurt too bad in these leathers except for a hard face plant at a mini race where I jammed a shoulder. That one hurt my rotator cuff, I think. I still can't throw a rock very well anymore, though I can, now lift my arm over my head without pain, finally. Hey, it's a rough sport. If you wanna race, be ready for the beating.
Anyhow, I survived the Daineses, but nearly every crash involved bruises and such even though the integrity of the leathers was never harmed. Modern stuff is SO much better.
Little things are improved on leathers every season from information gleaned in crashes at the professional levels and, not unlike helmet technology, that improvement in design trickles down. I stepped out of racing in '86 and back in '99 and in those 11 years, WOW, did gear improve or WHAT?! Of course, I could say the same about tires, heck, about bikes for that matter. But, the quality of those cheap Teknics shocked me. Dainese is a quality brand still and the cheap stuff 15 years newer is FAR, FAR better than the higher dollar 15 year old stuff, like by light years.
