Patagonia Men's Nano Puff Jacket, size M (fits like a Japanese L) See the Patagonia website for detailed sizing. Purchased from a used clothing store. This is a rare purple color, so please consider it if you're looking for one. The well-known Patagonia Nano Puff (gold) jacket. It packs down small into its inner pocket, making it convenient to carry. Great as an outer layer in spring and autumn, and as an inner layer in winter. It's a worthwhile item to own. Patagonia prices have increased due to the weak yen. Current retail price: 33,550 yen. Although it's new and unused, it has been handled by someone. Please refrain from purchasing if you are sensitive to this or seek perfection. Thank you.
