    Perfect fit for my Alpinestars jacket size L. Seems breathable in Texas summer weather.

    Fits nicely in the new AS jacket. Not super heavy or too uncomfortable. I’m pleased with this so far. I’m going to assume it will do its real job properly, if need be…but, hopefully I’ll never need to find out. Till then…

    Fits great in my size small Stella T-GP Plus R v3 Air Jacket. Doesn’t change the fit of the jacket at all.

    見た目は目の大きな立体メッシュですが、中心部を親指で押しても変形しない程度の強度があります。ジャケットのオマケについてくるソフトなプロテクターとは別物です。通気性も良いので蒸れません。 ジャケットに合わせてSサイズとMサイズを買いました。Sサイズは長さ39センチ、幅23センチ、Mサイズは長さ43センチ、幅26センチです。同じメーカーの同じサイズのジャケットでも、シリーズが違うとポケットの大きさが違います。装着するジャケットのポケットサイズを測ってから購入した方が良いです。

    I have been lucky enough to not have out this to the test but it is light, flexible, and fits in my alpine star jacket perfectly.

    This product is so good in quality, very light and protective.

The extremely lightweight, CE-certified KR-CELLi Protector insert features an articulated back shell plate for flexibility and riding fit, plus an advanced micro-structure cell design for efficient impact energy absorption and high levels of airflow.
