Ya, I felt truly stupid once I realized Gore-Tex is Teflon. REI is gonna need a makeover once this catches on.

Since learning about micro plastics from fabrics polluting our waterways, I'm keen to find alternatives.

I had an Australian style rain coat (dense weave, regularly reapply wax) as a kid. I couldn't find anything comparable locally.

Meanwhile, I got one of those fisherman jackets. I sweat so much, the only benefit I get is wind protection.
