I believe this size is suitable for infants up to around two years old. If you're concerned, trying it on at Patagonia would be the most reliable way to ensure a good fit. The material is of good quality, and since it's for an age where they don't get too dirty, I think the condition is quite good. There are no noticeable tears or stains, but please forgive any minor oversights. There is no name written on it, but there is a small tear on the fold line of the tag. I don't think it's anything to worry about. This is a cute jumpsuit that stands out even in the snow. It can be used reversibly.
