Men's Cotton Hooded Puffer Vest Best Sellers Men's Solid Color Cotton Vest

Too small, it's the right size very disappointed

The vest is good, warm, thick, covers the butt. The hood is small, only up to the ears, unfastens. The pockets are deep 👍 without a fastener. It will be good for size 48 with a warm sweater. There are no size identification marks. Photos later........

Runs small, but it's a good sleeveless jacket. I have no idea what to do with it now. How can I exchange it?
