Are there any options out there for a *breathable* aluminized fabric?
I have several ideas I would like to test adding an IR-reflective layer to, in order to possibly boost warmth. It either needs to be super duper lightweight & not durable (a protected, inner layer) or more durable and comparable in weight to regular UL nylons (15d - 30d).
What exactly is something like the Fugu jacket using?
Note: I'm *NOT* looking for a waterproof or WPB fabric. Just breathable like regular nylon.
