I have one of their “iconic” puffy jackets. I bought it cheap at a gear swap because it has a tiny rip. That has never worsened, which I believe is a property of the material. The polyester is quite durable.
I wear it about a third of the year here in Seattle. In the five years I have owned it I have washed it maybe once and possibly never. I don’t even wear it in the rain often because I have a rain shell which is also plastic and also doesn’t get washed.
I do also have some hemp pants from Patagonia. I wear those often. They made it about three years before they needed to go in to have pockets repaired from cell phone damage. Those fibers require farm land and water to grow. Repairs help mitigate that damage but it still exists.
I’m honestly not sure which garment has the most negative effect on the environment.
Not a perfect company, I mean almost all of their iconic garments are plastic, but they're doing far more than other technical outerwear companies.
