I had Olympia gear in my crash. It performed exactly as desired. There was not a scratch on me and the back pad prevented my spine from being snapped.
I replaced it with the BMW Airshell. I prefer this jacket because I got the optional back armor and it is clearly a more rugged piece of kit. There is more cordura and stiching seems a lot more robust. The mesh doesn't look like it will burn through as quickly, although that wasn't an issue with my crash. Still, I would not hesitate to use Olympia again.
