Reversible Patagonia quilted puffer was perfect for our son! Size was 12 months, but I removed the tag so we could wear it both ways. I think it runs a little big, I'd say 12-18months. We called it his spring snow suit - Ha! we live in a colder climate, so this was perfect for the shoulder seasons. It held up so well and is still in great condition. washed in gentle, unscented detergent. smoke free, pet free home.
