Update:
Considering the spidi defender, seen in the above post, or the knox contour race back protector and the attachable chest protector (the straps from the back protector run through it), both shown below:
Anyone have any experience?
I like the defender because it is one unit and looks solid and nice and thin. My only concern with it is whether or not the back goes down far enough to provide ample tailbone coverage.
The knox combo looks to be pretty awesome and the back part is CE level 2 which is mo betta.
I need to figure this out fairly soon to run my 'new' 1piece at the track...
