I wish that we'd come up with a replacement that's just as good first , and only then phase out the original. As an example of the right way to do things, consider that nobody banned leaded avgas before the FAA found and approved a safe unleaded formulation.

They can calculate the years of life lost if people excercise less due to no available substitutes, and compare it to the current expected years of life lost from the chemicals.

Considering they are called forever chemicals, I suspect the results will favor the ban.

Someone's running hobby is not as important as clean water. Neither is your omelette. I'm sure there are professional and medical uses for those clothes, but we can't just spew crap that never goes away into people who don't get a choice not to consume it.

Also didn't they have unleaded avgas for years? I thought the leaded gas was just to keep some really ancient engines running? Probably wouldn't have been that expensive to subsidize replacements if so.

Maybe like studded tires, for some region

Where are studded tires banned?

There are number of US states that ban them. There's a map near the bottom of the page here: https://www.tirebuyer.com/education/studded-winter-tires

I'd call attention to the "Upper Midwest": Minnesota, Wisconsin, Michigan, and Illinois. These are all states with severe winters and frequent snowfall, and all ban the use of studded snow tires.

I have one and I can't compare it to your 20 year old model, but I wear it skiing everday in winter, maybe 140 days of the year, I have fo 3 years and so far it's fine.

Ski-related followup: What do you wear over it?

Currently gortex bibs and a gortex patagonia ski jacket. If it's very cold, I wear a down vest over the fleece.

Underneath I usually wear a wool singley and wool long sleeve shirt.

This keeps me very warm and comfortable all day.

Has anyone tried wax cotton? https://www.fjallraven.com/us/en-us/about/our-materials/g100... I have some items from Fjallraven which is made from a cotton/pollyester blend and I find it to be amazingly breathable and water resistant (when waxed). The thing is, I own so much waterproof gear but I hardly do a great amount of anything in the actual rain, even if hiking or camping, I usually avoid wet weather, I suspect…

Cotton retains water. It’s the worst possible fabric for wet weather. Many people have died from hypothermia caused by their own sweat freezing in cotton garments. It could be argued that the entire motivation for creating synthetic fabrics is to eliminate the water soaking property of cotton.

It's cotton impregnated with wax, and it's a mix of cotton and polyester.

no other class of materials is anywhere close to perfluorocarbons in many properties, such as low affinity for both water and hydrocarbons (and consequently fats), and ultraviolet resistance coupled with softness additionally such levels of resistance to biodegradation are rarely found in combination with either of the previous two qualities no other known organic compounds, out of the currently 182 million assigned…

There's always active materials. We already have heated jackets, why not dehumidified jackets? Then again, I don't do activities where failure of my clothes could kill me, so I'm not sure how the market would respond.

i have been working on that for a while but my intended use is enabling autonomic thermoregulation in humid weather by condensing sweat

i hadn't thought of it as a useful adjunct to wrapping myself in essentially a garbage bag to stay dry in the rain

In Florida, living between the coast and the everglades, rain is a daily occurrence. Having grown up there for 20 years, I feel that rain doesn't phase me at all. I have questioned the averseness northerners have towards getting wet. Living in Maryland now, so many I've interacted with will just not go outside all day if there is rain. They've been raised by parents who've trained them to wait for the rain to stop, t…

It's all fun and games until you're just above freezing and soaking wet. Wet in the south is something completrly different from wet in Florida.

> Wet in the south is something completrly different from wet in Florida.

So, "the south" refers to someplace like the Falklands? :-D

For anyone not familiar with what makes Shakedry so revolutionary is its ability to be waterproof, highly breathable, and incredibly lightweight. Its weight and breathability make it incredible for active sports like cycling or running. These jackets weigh around 100-150g depending on features and size and can pack into the pocket of a cycling Jersey, all while being waterproof and preventing the athlete from overhea…

So does this mean there will be no waterproof+breathable, also reasonably lightweight sportswear from now and until something new is invented?

I keep waiting for cheap, durable, hydrophobic aerogel fabrics…
