Energy Saver!

I am using the Sleepout curtains on our west facing windows in the living room. They do a great job in blocking the afternoon sun keeping the room cool which reduce the need to run the a/c.

Used in a window directly facing the sunset & my young nieces are still able to go to bed while the sun is up. Nice, thick material & no synthetic smells.

Donna K.

Night Shift Worker

This is a great product! It was super easy to attach to the window, blocked out all of the light, and equally easy to remove. Highly recommend!

Our sunny guest room was a great place to nap and sleep bc of the Sleepout window covers! Thank you for making a great product.

These are true blackout curtains! Used in the bedroom for our newborn and it really helped with staying asleep. Now we have it in our bedroom and love sleeping in on the brightest of days! Only regret was not purchasing another set for the other bedroom.

We have “blackout” shades already, but they were not doing the job at all. Now with this product I can’t see my hand in front of my face in the middle of the day. My newborn is actually able to sleep now!
