Patagonia sizes are American sizes. This is labeled XS, but it's a Japanese size S. I bought this at the Patagonia store in Yokohama about 10 years ago. I wore it 2-3 times back then and have kept it stored after home cleaning. Patagonia recommends washing at home. Currently, the back of the neck is curled up. I've outgrown it, and I hope someone who will wear it can have it. I don't remember the purchase price, but I think it was around 40,000-50,000 yen.
