The Alpinestars bionic plus protection jacket is a great idea and over all fits better and wears better than expected. While riding the only thing I could say about the jacket was the I did not notice it was there and it did a fair job of protecting from roost where it did have padding. The padding could have been a bit more rigid and covered more surface area to protect against the larger rocks and get offs. I did develope a rash of bad arm pump while wearing the jacket that went away when I stopped wearing it. I believe that the device has some blood flow restricting issues in the forearm area. Overall the jacket is a great step in the right direction. It's amazing to me that there is so little protection out there for the shoulders ribs, and elbows; I'm glad that manufacturers like Alpinestars are taking the steps to develope a device to help limit the damages that motocross crashes can cause and look forward to the next generation of jacket.
It does not take the place of a chest protector, it did fit well but you would still need a chest protector, to redundant. It was a little pricy for what you gget
