Used it as a light jacket in the fall, now use it under a winter jacket.  The hood is very well designed and practical (not for show only) as it fits my boy's head perfectly.  He hates hats (what baby doesn't?) so it makes things much more convenient on those days when a thick winter hat is not necessary.  The cotton is very soft and the jacket retained its shape after washing several time (I was especially worried about shrinking as it usually misshapes the area by the zipper but it wasn't he case).  The zipper is plastic and small enough for a baby item.  It zips smoothly after a couple of months use.  Yes, we used it for two months already; this is a very rare piece of baby clothing that can be used for more than a month! We got 0-3 mo, my boy is now 4.5 mo old and it still fits (he is 90th percentile for length but only 10th for weight). It was loose at first, it now fits well on top of a long sleeve, hope to use it for a few more weeks, perhaps on short sleeves later on. Five stars hands down.
