Alpinestars Nucleon KR-Celli Motorcycle Back Protector, Black, Large

Fits perfectly in Alpinestars jackets. Very comfortable and high degree of protection CE rated. I used it in an Alpinestars air jacket and after installing did not even notice it was there during the ride.

This spine protector fits perfectly in my jacket. Its light weight and sturdy. If you have a jacket, you definitely need this to add protection for your ride.

light and soft, fits well, hope never to put it to the test

The back protector fits my jacket perfectly. Its lightweight. I cant even tell its there. Of course, Ill never know how well it works unless I crash.

Fits perfect in my Large Astars bomber jacket. This thing is super lightweight and barely noticeable, love it.

Just my opinion but this should easily be ce2 for the cost.

Super! adapté à mon blouson alpi top! Pris en taile S.

This fit perfectly in my European size 56 Leather Alpinestars coat, it is night and day protection compared to the Original flimsy foam piece!!

Ｌサイズを買ったのですが、SSにのるとヘルメットがプロテクターに当たって首が疲れます アメリカンに乗るときは首が起きてるので大丈夫です 個人の体形もあると思いますが、多分Ｌはでかすぎです
