I received these today, I got them in indigo and the color is lovely! As other reviewers have said, they are not blackout curtains, however I think that this is a mistake in the listing; the packaging never claims that they are blackout curtains, only that they help block sunlight to keep your home cool in the warmer months, which is consistent with the thermal features. As far as I can tell, they're not at all intended to be blackout curtains, which is fine with me since I didn't need them to be. The material is a very tight weave, but a fairly thin material, so they hang like normal curtains. I've seen other thermal curtains that seem more like hanging a quilt from your windows. If that's what you're looking for, these aren't for you, but if you're looking for lightweight curtains with insulation properties, these are perfect, and won't put stress on cheaper curtain rods. In my bedroom, I do have thicker curtain rods, and the pocket is large enough to accommodate them as well. These are exactly what I needed, I will be ordering more for other rooms!
