Simply put, we love the blue color, it is "slightly" warmer than our thinner one but that does not mean it's not worth it, it's not overly warm unless you keep your house at 85 degrees, then yeah, you might be hot. We put it inside a duvet cover but ended up taking it out since the blue was nice. It does not have the little fabric piece to tie the duvet cover too, but we had no issues with that at all, so don't let that stop you either. We're happy with it and would buy more for other rooms.
