Sleepout’s design allows you to hang your blackout curtains vertically or horizontally, making them an easy fit for any window. Plus, you can combine two or more curtains to cover larger windows.
✅ A Truly Peaceful Sleep
Sleepout's blackout fabric is Greenguard® Gold and OEKO-TEX® Class 1 certified, the safest blackout material available. It blocks 100% of light while adding thermal insulation and noise reduction, so you fall asleep faster and stay asleep longer.
