Like new women's Medium Patagonia Nano Air Jacket. There was one small hole on the back of the collar that I covered with a patch that can be replaced or sewn. Otherwise like new condition. 60 g synthetic recycled polyester insulation with a ripstop nylon shell. Fall 2017 model. Self stuffs into chest pocket. The Nano-Air Jacket was made to be worn for the entirety of your aerobic, start-stop mountain activities, so you’re never slowed down by having to change layers. Stretchy and breathable FullRange insulation dumps excess heat when you’re working hard and keeps you warm when you’re not.
