They are great until they pop... One failed in a crease for unknown
reason last week, makes a real mess...

That silicone fluid is insidious. It leaks imperceptibly. You feel wetness
on your neck but can't find any water. Then your shirt sticks to your skin,
but you still can't find any leaks. You have 6 hours of flying left for the
day.

I went back to foam. I use the Temper foam aftermarket ones now. They are
just as comfortable as the gel seals were, but don't leak.
