Men's Patagonia Nano Puff Jacket. Navy. Size medium. The Nano Puff is a fantastic and popular upper layer choice to stay warm. This jacket is in used condition, but is fully functional. It doesn't fit me anymore is why I'm selling it. There are some repairs that have been done on it by Patagonia Repairs, they are pictured. It also had the insulation stiffened up by a dryer that got too hot, but this doesn't present a functionality problem. It's a great jacket that's been well loved but also taken care of and professionally repaired. There is plenty of life left in it, I would keep it and wear it for work if it still fit me but it's too small. Price negotiable, but these things are several hundred $ new!
