RevZilla Store asked: Why did you choose this?
Sandra F: For CE certified level 2 back protection in order to replace the foam piece that comes with the motorcycle jacket. Oct 29, 2014
Joaquin F: Wanted improved back protection for my Alpinestars Celer jacket. Oct 13, 2014
William K: Anthony's review, of course! Oct 6, 2014
Yang L: For best protection against high impact area. Sep 30, 2014
Anthony D: Upgrade to the AStars Celer jacket I just bought. Bionic armor is level 1 and $30 more. This looks to be a win, hopefully it fits and performs as well as all other Astars gear. Sep 25, 2014
caleb s: so i can have protection Sep 23, 2014
A shopper asked: I am purchasing the Alpinestars Stella Gunner WP textile jacket in a size small. Should I purchase the Alpinestars Nucleon Back Protector in small or medium? I am 5'2" and weigh 110 lbs. I am also considering purchasing the Alpinestars Bionic Chest Pad, although I'm not sure how much protection the pads really offer.

I'm a new rider on a 2004 Honda Rebel 250CMX

Any suggestions are welcomed!

Michael S: Hi - I am also a new rider (2014 Honda CB500f). I am 5'7" and 175 pounds and where a Large Jacket because of chest size. The protector is light and semi-flexible. I got a Medium and it fit fine. I think Revzilla has a return policy so I would go for a medium if you where a Medium jacket. If you where a small jacket, then I would get a small. That is purely my guess. You should contact Revzilla; they have been great about answering questions for me. Oct 29, 2014

Robert J: At 62" tall you should get size small in the Alpinestars Nucleon Back Protector. The women's model of the Bionic Chest Pads will definitely give you more protection and is highly recommended. Oct 29, 2014

William K: I'm thinking the small one. Measure the foam pad that came with the jacket and order the appropriate size listed on the chart on the Alpinestars site. Good luck. Ride safe. Oct 29, 2014
