This is a gray Patagonia sweatshirt, a trainer. It's not as thin as a long-sleeved T-shirt. It features a flying fish design. It's rare and I think it will be useful this season. The Patagonia logo is understated, making it a piece that only those in the know will recognize. This is a pre-owned item, so please check the condition in the photos and purchase only if you are satisfied. This is a Patagonia size, so it's quite large. Although it's XS, it should fit someone who usually wears a Uniqlo M size. - Brand: patagonia - Size: XS - Design: Gray sweatshirt with a flying fish graphic Thank you for looking.
