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

Very nice product and Im sure will work well in a spill. However, it does make your back a lot hotter so be advised.

I liked that it fit! A bit sister then i thought but it is C1

Very good quality

fast shipping, great product. as advertised.

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。。。

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.

I bought the back protector after purchasing knee pads for my alpinestars street jeans. The back protector was notebly more comfortable comepared to the Spidi protector I had in before. Bear in mind the nucleon is made for my Alpinestars GP Plus jacket (and others) and that has some to do with the noteable comfort but most of the comfort comes from the the design.

Es lo que esperaba , buen producto

Se adapta excelente a mi chaqueta Alpinestars

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.
