I'm in the market for a 'green' jacket to go with my ride.

I am looking at this one on riders discount. http://www.ridersdiscount.com/street-ge ... 106396.php
Just want to get peoples thoughts on protection it offers. How good/what does "Rock Tex™ 600 outer shell" do for you in a crash? I am guessing no where near a leather jacket?
If you know of a shop/online where I can buy a kwaka leather jacket let me know

Regards,
Vivek
