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

I have more than a few Alpinestars jackets and I prefer not to switch these protective inserts around so I just purchased one for each jacket. I hope I never have to use them but I sure feel whole lot better having them in place in case I do. I can tell their quality is top notch and their construction is durable. Shipping was fast as always and Amazon is the place to buy the stuff!

Very good quality

Took it out of the box, very well built, feels nice.. Should do the job!

For the price is a nice back protector for any Alpinestars jacket or any other racing jacket you may ride in the street.

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

Se adapta excelente a mi chaqueta Alpinestars

With this back protector you will hardly know you have it on, its light and air flows nicely through it. There should be more of these type of air flowing protectors on the market IMO.

Buen protector de espalda. Necesario para chaquetas alpine star. Buena calidad. Nivel 1.

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

The Alpinestars Nucleon KR-Celli back protector is a great, afordable, entry level choice for a CE level 1 rated back protector. Its fairly light, breaths well, and decently flexible after wearing for a while. Its a good choice if you want some protection without breaking the bank. I use it in a cafe style riding jacket, and it blends into the jacket very well.
