Straight from Bell's site:

'The SE03 3mm DSAF shield is an injection-molded optically correct polycarbonate face shield with a Double Screen Anti-Fog insert for superior fog control. The SE03 3mm DSAF shield uses the SV (SE03/SE05) pivot kit, is compatible with tearoffs, and is available in a variety of colors. Compatible with the GTX3 Carbon, GTX3, GP3 Carbon, and GP3.'

It's used but not nearly enough (because a sports racer drove over me; while I was wearing my smoked visor), and it's even got a couple of tear-offs still on it.

$60, and I can bring it out to the track any race day.
