#2I am not optimistic about the future of sustainable specialized materials.
It seems very likely that the same structures that give modern high tech materials their unique abilities are the same ones that make them so environmentally unfriendly.

#3"All" is a bit over the top. I have Carradice bags and a Poncho and they work fine. I have ridden in very heavy rain without issues.

#4Maybe we can mimic some of the effects found in nature without chemicals and make hydrophobic surfaces based on their nano-level properties?
Or like ducks use preen oil, something closer to that.

#5> Gore is committing to a "goal for being free of PFCs of Environmental Concern." That doesn't affect the ePTFE membrane though because, according to the brand, ePTFE "is inert, insoluble in water, extremely stable and not biodegradable. Therefore, it does not degrade to become a source of PFCs of Environmental Concern."
Gore continuation: biodegradable:degradeable ::(->) unbiodegradable:undegradeable

There is already an XVIII century technology and WWII popularized option called millerain. But it requires some maintenance and isn’t “light” as preferred by cyclists and runners.

Isn't nature made of chemicals?

#8Given that many cyclists also have deep climate anxieties and conservative (with a small'c') attitudes it sounds as though 1970's era pvc coated nylon and cotton will make a resurgence

We are in the middle of a biotech revolution. Figuring out how to scale up bioengineered materials is a likely source of impressive materials.
Nature is full of stuff like spider silk, chitin, bone, phosphorescent materials, sponges,etc.

Yeah wax was used to make tents waterproof as well. But it’s quite a bit heavier than plastic thread
