I didn’t know Gore-TEX was ptfe. Damn, those things last forever (like BPC).

Think plastic is a problem? PTFE is way worse.

Those are the microplastic we are going to find in breastmilk forever.

Yeah a lot of outdoor manufacturers have been trying to make more eco friendly waterproof gear that doesnt use PTFE. Patagonia in particular has been really trying hard to get rid of their use of them: https://www.patagonia.com/our-footprint/ptfe-polytetrafluoro... From what I understand the gear that doesn't use PTFE is unfortunately still not great or have the long term durability as goretex. Hopefully soon they'll figure out a good replacement!

Klättermusens Cutan fabric performs quite well. Especially compared with Gore.

PTFE is also used in implants specifically because it completely inert under normal conditions.

which sorts of implants? i know, for another example, some orthopedic screws are actually calcium which are made to reabsorb, which i have 3 of myself from an athletic injury repair by an NFL team surgeon (maybe relevant if the materials change for type of repair).
