Setting aside the issues from waste during the manufacturing process and the messes that have been made (see 3M plants for example), is the actual Gore-tex product itself hazardous? Like, how much of the material do you have to eat, and how edible is the Gore-tex product? I get Teflon coatings scratching and getting mixed with the prepared food, but I typically don't go around gnawing on my clothing. Does Gore-tex leach anything that can absorbed by the skin while wearing it?
