I recently bought a Dainese Air-Tourer S-ST Textile Jacket.
The build quality seems good, the ventilation is absolutely superb. The back protector is an extra. I would doubt the jacket would afford much protection if things go wrong and you ended up sliding down the road though.
Thanks! Got one now, not sure on model name, was told even though mesh, customer had no damage after a spill....... Just weather specific, but in the heat am looking to enjoy it!!!!
