This is Patagonia's classic R2 fleece jacket. It's made of Polartec fleece, making it lightweight, warm, and durable. Anyone who has worn an R2 will know how great it is. The size is S, but it fits like a Japanese M size. It fit me perfectly at 165cm tall. Therefore, I've listed it as a size M. It will be folded compactly for shipping. Please refrain from purchasing if you are overly concerned about wrinkles caused by folding during shipping. To prevent product substitution, returns and exchanges are not accepted. Please understand this before purchasing and only purchase if you are satisfied with the item.
