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

Mサイズ。縦43cm、横25cm エアスルーのプロテクターでCE規格は、これ一択だったので購入。さすがにこれからの季節エアスルーでなければ背中に熱がこもって暑い。 サイズはHYODのD3Oとほぼ同じ。HYODのメッシュジャケットにぴったりでした。重量はD3Oよりやや軽い。 クシタニのCE２プロテクターよりひと回り小さく長さが３ｃｍ短い。クシタニのアメニタには入り、がたつきませんが、やや短い。Lサイズが縦約46cm、横約26cmなのでクシタニ用にはLサイズの方がいいかも。

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.

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

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

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

Wanted a better spine protector than my alpine jacket came with (the one that the jackets come with is a joke, just foam) Definitely feel much safer with this on my back

Paraschiena molto leggero e comodo

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

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.
