Patagonia fleece. I bought this from an acquaintance about twenty years ago. I haven't had a chance to wear it in the last few years, so I'm putting it up for sale. I believe it's authentic, but I can't say for sure since I didn't buy it from an authorized retailer. Please refrain from purchasing if you have any concerns. It's an old item. The condition is typical of used clothing. Please check the images. I didn't find any tears, frays, or holes, but there might be some I missed, so please only purchase if you understand that it's used clothing. If you have any questions, please ask in the comments. To prevent switching, I do not accept returns or refunds. I cannot offer a discount, thank you for your understanding. I will fold it up small for shipping.
