I bought this comforter a few months ago in the chilly winter, and now we're heading into the hotter days of summer.  When I first bought this comforter, it shed quite a few feathers.  Because it's hypoallergenic, I haven't sent it to the cleaners, so I can't tell you how well it will retain the down after a cleaning.  It was decently warm in the winter, but I definitely had it paired with some flannel sheets and an extra cotton blanket for good measure.  Where I live, it tends not to get below 20-30 degrees, so bear that in mind if you live in colder climes.   The weather has been warming up, but I've still been able to use the comforter.  It seems to be a pretty good year-round option, but we'll see how it fares heading into July.  Overall, I would recommend this.
