The new law will affect all kinds of things Coloradans buy and use every day, that are made using something called per- and poly-fluoroalkyl substances, or PFAS.
don't replace it if it still works. that would completely defeat the intent of being environmentally friendly. getting rid of it entirely just makes it someone else's problem. it will still exist somewhere and still be breaking down.
if it's breaking down and needs to be replaced anyway because it's a decade old then ignore me lol.
Patagonia is good as long as it's not a Goretex. There's also Vaude which is really ahead when it comes to environmentally friendly designs. I think RR is another one.
You will always need to reapply the DWR layer every now and then depending on your use. Most people use Nikwax.
