I saw this on outsideonline
I have no idea if this actually works
I think what it is is that they make fabric with fibers with imbedded ceramic particles that make it reduce IR radiation
Sort of like a mylar space blanket, except it’s fabric and breathable
Anyone heard of it?
They have a plot of radiation energy, but no plot of effective R value or how much it reduces the lower comfort temperature
