I roll with an A* Bionic, it's comfortable under leathers and has integrated chest protectors, though the Bionic 2 offers a bit more protection. Link provided on STG site: http://stores.sportbiketrackgear.com/Detail.bok?no=2822
Michael at impact Armor is the man. He shipped Kalebs straight to Barber to make sure we had it for the first ride of the year. New Chest and Back Protector for 2013 season. Great company
I bought a Know Chest and Back Protector combo before the beginning of the track season. I wore it at ACC over Memorial day weekend. I only noticed it when zipping up my leathers before sessions, but never noticed while riding on the track. It didn't impede my movement at all. I found that I don't like connecting the chest protector to the back protector, when I did connect them, the back protector would creep up during the session and by the end of the first day had started to rub the back of my neck raw. After that just simply insert the chest protector into my leathers. I hope this helps in your choice of protection. Nick
I've used the T-Pro back and chest protectors for several seasons. Happy with how they protected me during a crash and hold up to wear and tear. US importer for Forcefield T-Pro is Johnson Leathers out of San Francisco. They are good people to deal with. Always fast response and good service.
all this talk makes me want one .. im thinkin about modifying my old hockey pad chest/shouler/back protector and see how that works .. save money and its strong stuff
