Thing to be aware of is that a m/bike helmet can scoop the water during a high speed MOB and potentially cause serious neck injury. What Gecko (and I assume Gath) claim is that their chin strap is designed to fail in that circumstance so that the force on your neck is much reduced.
Now of course people don't fall overboard regularly. When they do fall it is often not at speed, and presumably even then only a fraction of those would be at the angle most likely to maximise scooping...
