Thanks a lot for all this information!
I was at the Moscow Dealer and looked at the jackets. I already have Vertigo air boots and I like a lot. Now I'm thinking about a Spidi jacket. Unfortunately they only had one big size of Ergo Expedition no Ergo pro. And after all the reviews and your advice I think that Ergo pro would be the best option for the combination of the best abrasion resistance and good ventilation. I'll be in LA at the end of the month and I hope to find the Ergo there.
Do you know of any big MOTO stores in LA where I can definitely find this jacket?
Again, thanks a lot for your help.
