Patagonia Men's Nano Puff® Jacket. The jacket is in excellent condition. Patagonia often specifies the exact shade of its colors, but I couldn't find this one listed. I do have another Patagonia nano vest in blue, called “Andes Blue." Check the last photo where I placed both items side by side. This way, when you search for Andes Blue and view more photos, you'll get a good idea of what the actual nano puff jacket looks like. I can say that it is only slightly darker than Andes Blue. Size: Medium Color: blue “slightly darker than Andes Blue”
