This back protector worked well for me
Since buying this protector I crashed in a dog-leg at my local track. While I did break some bones (collarbone & ribs) my back remained protected.

Great Product and comfortable!
I have had this back protector for about a couple weeks. I haven't been able to ride to much but have commuted to work a couple days wearing this. My commute is about 90 miles total and i can say that after a little riding the protector molded to my back and i didn't even notice it. I wore both my larger winter Jacket and my summer lightweight smaller jacket and it fit underneath both fine. I cant say to much about airflow because i have been riding it colder weather but with the comfort and honeycomb features i can see how you will get great airflow and not sweat a ton wearing this. Overall a great product and hopefully i will never have to see how well it protects my back.

Do all the Alpinestars back protectors have the button snap to allow me to snap it into my Alpinestars Motegi one piece suit?

Is this compatible with any neck braces? Looking at the Leatt GPX Trail, does not look like they will fit together.
