Pinlock principle?

[Itchy]

It works by double glazing and creating an air gap between the visor and the insert right?

Therefore does this principle work on any polycarbonate thing that is near your face?

I have a set of these you see...

I also have 3 spare lenses. So if I get some silicone and double glaze it very closely then it ought not to fog right?

Right?

Pin lock also has a moisture absorbent coating on the 'inside' surface of the insert. It absorbs latent moisture in the air trapped by the insert and it's silicone seal and the visor.

I say yes if you can fit them so they don't touch each other which I imagine to be challenging. The concentric adjusters on a pinlock system allow for very minor adjustment.

[edit] good point MCN...forgot about that absorbency stuff.
