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…

Often, yes: novel compounds can have side effects which take years to understand (e.g. DDT‘a impact on bird populations lasted past the point where its effectiveness was rapidly tapering) and depending on what characteristics something was picked for you can end up with something which doesn’t biodegrade and is thus a long-term problem if it doesn’t turn out to be harmless.
The fact that these are man-made is irrelevant to their harmful effects and framing it as if it was contributes to the persistence of the natural fallacy.
Thinking about it for a minute, I’m not sure why we need fluoropolymers for waterproof technical fabrics. Unless I’m very much mistaken, PDMS rubber, polypropylene, polyethylene, and other materials provide similar levels of water resistance, without requiring the use of fluorine-containing compounds. Most explanations I read for Gor-Tex-type materials using PTFE (e.g., [0]) reference the hydrophobicity of the materi…

Sorry, I meant PFC. I’ve edited the comment.
Yeah you're thinking of older style goretex membrane laminants. They'd have 2 or 3 layers with a goretex membrane inside and an outer shell of non-waterproof fabric to protect the goretex. The outer shell would be treated with a PFC spray to make it water resistant and keep from soaking up and holding water (which makes the inner goretex layer not breathe). Goretex shakedry came out a few years ago and changed things…
Certainly seems like shakedry is being phased out because it contains a (banned) toxic chemical. What am I getting wrong?

Since I watched the movie “Dark Waters”, I’m trying to avoid those PFO(A|E) as much as I can. Threw all non-stick pans away and learnt how to cook with just cast iron or inox pans. https://en.m.wikipedia.org/wiki/Dark_Waters_(2019_film)
I ditched them a while ago as well. I only use cast iron or stainless steel and it makes me wonder why I ever bothered with non-stick before.
Because they are incredibly useful when it comes to certain kinds of food, especially eggs and fish.
I find all the "self-congratulatory" posts on the topic of non-stick pans, and demonization of people that use them, of the "thou doth protest too much" quality. Tons of renowned chefs, like Jacques Pepin, have spoken of the benefits of non-stick. There are ways to get closer to the quality of non-stick with other techniques (e.g. a meticulously cared for and seasoned cast iron pan), but it takes a lot more work and is still finicky.
I totally get it if you don't want to use a non-stick pan because of health or environmental concerns (I find there isn't much to be concerned about if you're not using too high heat on the pan), but this pretending that non-stick pans aren't super useful is silly. I'd challenge anyone to make a perfectly light and golden French omelette with, say, just butter on a non-nonstick pan (it can obviously be done, it's just way harder).

I remember US army like 10 years ago compared different fabrics and have found eVent was performing significantly better than Gore Tex. Does ShakeDry really better than alternative according to some realistic tests?
ShakeDry is much better than eVent in my experience running in very wet weather. eVent is fine for shoes (I’m pretty sure it’s what Altra uses in the weatherproof Lone Peaks) but for both weight and performance, ShakeDry is the better jacket material. I’ve spent way too much money on running gear over the years and ShakeDry laps the field in waterproof + breathable. To be honest, I don’t particularly care what perfor…

I don’t think the material lasts long enough to have multiple users. My experience of ptfe and related chemicals is that they wash out and the material degrades over time worth wear, so they don’t stay water-repellent very long. If they didn’t degrade quickly, they wouldn’t be such a threat to the environment. Edit: Sorry, I didn’t mean PTFE above but PFC.
Goretex isn't a coating though, at least with their membrane stuff like shakedry. The fibers themselves are PTFE. It doesn't wash away over time. As I understand it the environmental risk with these jackets is from the production process and PTFE use there. Once it's a membrane it's inert and stable.

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.
Odd choice. Writing “18th” is faster for the writer and the reader.

Weird, I'm a keen cyclist and very into outdoor gear, and I've never heard of it. There are now many waterproof fabrics though, it's very hard to tell one strong claim from another.
Shakedy is however a gamechanger for anyone doing ultra distance and self supported racing. The ability to bike through a rainy night without worrying about Your upper body being wet is nothing short of amazing. And I say that as a proud owner of a not-too-old Goretex Pro mountain jacket and some older membrane jackets before that.
