Saved my life.
A car pulled out without looking and I T-boned them at 80km/h. My chest impacted either the car or my handlebars, leaving me with a punctured/bruised lung and cracked ribs. I don't want to imagine how I would have fared without these chest protectors installed.

Alpinestars KR-Ci is Awesome !!
Bought these to put into my 2019 42/52 Alpinestars Missle TechAir 1pc Suit.
The M/L/XL fits spot on. its really flexable once its warm and breathable. Also its ce lvl 1 so you get some extra piece of mind. Feels great in the suit too . Really glad i made the purchase.. way better than keeping the foamies.
Very fast F9 shipping.. thx again Alpinestars and F9!

Perfect fit
First off, I have no idea what people are talking about that it doesn't fit without trimming, unless they ordered the wrong size. Slide out the original pad, take note of its orientation and slide in the armour. Line up the Velcro and seal it shut. Easy. For reference I wear a Jaws leather jacket in size 46/56 and ordered the M/XL.
Second, although I really don't want to find out how much better it is than the foam it does feel much more substantial in the jacket and gives the impression it would reduce or prevent chest injury.
Worthwhile quality upgrade.

Quality as expected.
Bought these chest inserts to go with the back protector insert I bought years ago.
The size chart is true, and the quality is same as other inserts. Solid product.

Great Upgrade
Bought these with my Alpinestars Jaws Airflow. Great upgrade from the foam that came with the jacket. Didn’t affect the fit of the jacket.
They were a royal pain to get in the jacket and secure the Velcro for the pockets since I couldn’t see what I was doing. Took a couple tries to get each positioned and secured properly.
The M/XL were the same size as the foam protectors that came with the jacket.

Perfect additional protection
I bought this for my Alpinestar jacket. I took the size large, and it is a bit big for the pocket of the jacket. I had to trim it in order to fit perfectly.
