This is a Patagonia M's Cap 4 EW 1/4 Zip Hoody, purchased in 2014. It's a size S, but since it's a US size, it's equivalent to a Japanese M size. I haven't worn it much and have kept it stored at home. There's no pilling around the neck, cuffs, or chest zipper, and I think it's in good condition. Please check the images for details. Thank you.
