I love this jacket. It is very comfortable, breathes well, and the protection is great. I came to test its protection the second track day I road with this thing. The fork seals on my CR had blown the weekend prior and I did not realize exactly how much fluid had leaked out. Long story short, I hit the first table top nose extreme high and when I landed the forks bottomed out, throwing me hard chest first into the bars. I felt it, but it didnt even knock my breathe out. So, I was very, very happy with how well it dissipated the brunt of the impact. I do not ride the track without this on.
I did have to cut the sleeves off of mine because it was cutting off my circulation. Im not a big guy by any means. Im 6'1" and 184 lbs... so I do believe the sleeves are made a little too tight. Also, I wasnt a big fan of the elbow pads.
If I did it again, I would have saved 25 dollars and bought the vest instead of the jacket, but all in all I think this is a great purchase.
My only real gripe is the fact that this jacket does not work with the Bionic neck brace. I spoke with an Alpinestar rep and they said that they are still working on a jacket that is compatible with their neck brace. How does the bionic jacket not work with the bionic neck brace?????
