With a window open, the sun came right through. They are not even remotely blackout and extremely cheap material.

Nice blackout curtains..and the right size..It's very difficult to get 63" panels. Right size and the right color

Very best room darkeners yet, keeps light out..great price

[This review was collected as part of a promotion.] I have had up my Eclipse Khloe 100% Absolute Zero Blackout Solid Textured Thermaback Curtain Panel for several weeks now and I am very pleased with how well they keep out the day time sunlight. I really appreciate how well this curtain keeps my room blacked out, but cool as well, I have great comfort on a few fronts. I am a big fan of how these are thick and have a lovely texture to them, so I am styling and comfortable at the same time.

[This review was collected as part of a promotion.] I got this for my bedroom. My husband works thirds and needed to be able to rest in the daytime but the light makes it near impossible for him to sleep. These eclipse black out white curtain panels are perfect to made it too dark but still stylish for any room. I highly recommend for anyone with trouble day sleeping. As this is everything you need. Thick fabric but easy to wash and doesn't need ironed looked nice from dryer. I like the metal hooks make it easy to hang the panels by.
