My review will be on a very specific use of the Split Jacket Wind Gasket.
I thought I could use that for skydiving and ... I was wrong.
When you fall down at around 200 to 300 km/h face down, you don't really want to have the gasket detaching and poking your eye/eyelid. But that's what happened. This wasn't such a great experience at all.
So, maybe for other uses it's a good idea, but for skydiving, forget about it.
