    A-Stars Chest Protectors

    True to size, soft and pliable for installing and barely noticeable when wearing in my Alpinestars jacket. Definitely worth the extra protection.

    Chest inserts into Track Vest 2 in seconds. Full protection CE II front and back plus additional pads baked into vest. Perfect under Motegi V2. Best cooling set up for heat. Thanks to STG.

    Perfect upgrade!

    Fits my A*Stars track suit and both the perfed leather and text jackets. It's better to upgrade before an accident then wish you did after the fact. Been wanting and waiting, finally decided to pull the trigger. Picked up the Lg and it fits the pockets spot on.

    Good add-on for an A* Atem suit

    Posted by Josh on 27th Oct 2016

    I just recently bought an A* Atem suit (52/42) and the chest inserts that come with it are pretty flimsy. I bought the larger size inserts and they fit perfectly in the pockets. I'm not going to ditch my Knox chest protector just yet, but this was an easy and cheap upgrade to maybe make the suit a little safer.

    Even more protection...

    Posted by DannyBoy on 7th Dec 2015

    I purchased the Alpinestars Nucleon KR-Ci chest Inserts to go along with my new Alpinestars Jaws Perforated leather jacket. Easy to remove the original foam chest protector inserts and install these. Very nice and noticeable difference in the amount of protection these pads offer but they did not take up any more room in jacket, the Jacket still fit just fine.

    great item

    Posted by art on 7th May 2015

    replaced the bionic chest pads with these. what I like about these is the conform to you chest. while you feel them in there you don't have pressure points with them as you do with the bionic version
