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.

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!

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.

Sehr leicht das Teil, kommt mir relativ kurz vor in der Größe, sonst alles super.

Very light weight, and breathable through a series of honey comb like openings. I expect it will be very comfortable and pretty much disappear once installed in a jacket.

クシタニのエアコンデントジャケットを購入したのですが、標準装備の背中プロテクターは通気性が皆無で背中に熱がこもります。かといって、別売りの通気性があるものですとペニャペニャで防御力が心配なためダイネーゼの物と迷いましたが値段の関係でこちらを購入。重いといえば重いですけど、まぁ許容範囲かなと思います。軽く調べたところクシタニ標準は150g、HYODのD3Oは300ｇ、これは250～300ｇくらいらしいです。 Ｌサイズで、クシタニＬＬサイズジャケットはぴったりでした。 通気性はよくなったので、おおむね満足です。もうちょっと安ければいいんですが、ダイネーゼのだとこれの倍の値段ですから。。。

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

Flexibilität genial, man spürt ihn kaum. Winddurchlässigkeit, speziell im Sommer, wunderbar.

My son was wearing this when he was involved in a motorcycle accident. He impacted an SUV that pulled out in front of him when he was going 45mph. He was thrown over the vehicle and landed on his back. He had no spinal injuries! I am so grateful we invested in high quality personal protection equipment.

Well worth the money
