Size large Patagonia puffer with real down. Too big for me had to size down. There is 1 spot to front lower right. Not sure if it will come out. I never tried to stain treat it. Barely visible unless looking hard. Below is website description. The perfect warmth for just about everything, our classic Down Sweater is lightweight and windproof with a shell made of NetPlus® 100% postconsumer recycled nylon ripstop made from recycled fishing nets to help reduce ocean plastic pollution, and insulated with 800-fill-power 100% Responsible Down Standard down certified by Control Union (CU 880272). The purchase of Responsible Down Standard certified products demonstrates demand for better animal welfare practices in the down and feather supply chain.
