Simpson Hybrid S on sale July 2017
Simpson's Hybrid S 3-point belt compatible FIA-approved head & neck restraint device is on sale during the month of July.

It is designed to work with the OEM 3-point belt system, but it is fully compatible with racing harnesses too.
I think this is a great safety item that is worth having if you track your car. I have one that I use with both of my NCs, one with OEM seats and belts, and other with roll bar, race seats, and 6-point harness. It works just like a regular HANS in the latter case, and may even be a little more secure since the Hybrid has straps that tie into your harness sub-belts.
You can get it with M61 or sliding post anchors.
