Amazing! I finally pulled the plug and ordered four. My house gets so hot during the day/late afternoon all due to sun positioning. As a 44 year old hot enough woman, I was asking for a new air conditioner even though I knew it probably wouldn’t fix the sun. I finally decided I’ve blown money in worse ways, why not give these a try.

I didn’t want to take down my current average blinds/curtains, and these worked beautifully. *I do have one small bathroom window that looks pretty awful with all the bunched up extra fabric, but you know what, I can now get dressed in there at 5:30PM and not have a come apart from heat exhaustion. I may have my window lady alter them, but maybe not. I only have these on back of house windows where no one can see them. They look better than tin foil, but still not a clean look and I don’t want to take down and put up every day.

My goal is to put them up each June 1st, and leave them up until October probably. It stays hot in the South, but usually by October/November it’s not 103!

Got these after reviewing the much more expensive (and often uglier) alternatives like metal framed toolless insert blackout shades ($500) and professional window treatments ($1000).

They are truly black-out, heavy enough not to move too easily, and cleverly portable. Love that they're universal size - we have large 5' x 3' ish windows and didn't even need the XL version.

At first they seemed to be aesthetically meh (they needed heavy ironing upon arrival and the top edge of the curtains in particular seemed to sag between the velcro'd corners, leaving a gap) but with a set of attractive braided magnetic tie-backs from Amazon and drawing the shades in front of the gap, they actually ended up elevating our space and making it comparatively more bedroom-y and designer looking than without!

I'd love to see more color options, tie backs sold with the curtains or as accessories, and perhaps a Velcro strip or other solution for the top horizontal edge issue (but easily DIY'd).

Very happy in the end :)

They really offer white and they block out light

Sturdy, stable, well made, extremely easy to hang, creates complete darkness, love the versatility to bee able to hang either direction and a handy travel bag. I have beautiful windows with incredible views and didn’t want to install blinds, these shades are perfect especially in the guest rooms

Installed easily, and does an excellent job. Already recommended to friends at work.

Our nursery has a little nook with an opening that let in a lot of light. The large curtain is perfect! Love how easy it was to install and damage free it’ll be when he no longer needs them when he’s older or we find a more permanent solution that probably won’t be as effective as this curtain! He was struggling so much with nap time. Getting so distracted with leaks of light with the curtains we had up on the inside. When we noticed a small defect, seriously so small, customer support went above and beyond to resolve it in a way I didn’t expect! Great support and company. Thank you! Purchased a travel set too for an upcoming trip!

I’ve tried so many diy’s and “blackout” curtains, but this is a noticeable difference. I personally think the travel ones are the way to go. We use it mostly in our daughters bedroom, but when we go to our nanas house it’s quick and easy to pop them off and bring them to her house for naps. Simple, easy, genius. You need them. They’re pretty expensive but I truly don’t think you’ll regret it! You’ve already made it this far to read the reviews, you may as well try them risk free.

We need blackout curtains esp when we travel. So many resorts do not have complete blackout so these are so easy to pack and bring with you anywhere! We love it! We did notice though that you need to put it down and pack it in the mornings and put it back up every night because the suction cups will fall over time. When this happens, we simply wet the suction cups to adhere to the glass better. It works like a charm! Thank you sleepout curtains! Life changing for travel! 🥰 as you can see we are at the beach and the resort only had blinds that does not completely block out the sun in the morning.

I am obsessed with sleep optimization and hate it when I go to an Airbnb or hotel and they have poor window treatments that make it impossible to sleep because it’s too bright. My sleep out curtain is being packed in my travel bag every time from now on! These actually black out my room 100%. So easy to use too.

AMAZING and blocks out 100%

The two SleepOut Portable Blackout Curtains were easy to install and work so good to block out light in our guest bedrooms. They are portable and so convenient to travel with.

Great product and super easy to install!

I would like to focus my review on a problem that was solved by the experts at Sleepout. I recently had a small issue with my blinds and would have been understanding even if no action was taken; however, that clearly does not align with the Sleepout mission. The team responded to my concern by developing a solution and ensuring it was corrected in a timely manner.

Huge shoutout to the entire team, as this was clearly a collective effort rather than the work of just one individual. I will certainly purchase from Sleepout again if I need another blackout blind.

They are fabulous, super easy, and do a great job, in fact the bedroom is pitch black!

I was skeptical, but purchased one in the hopes it would help. A week later I was staying at a friend's, and her guest window faced the morning sun with only sheer curtains. The portable curtain went up without a fuss, and I slept well past dawn without wanting to claw my eyeballs out in frustration, and I didn't have to sweat under an eye-mask like a moist raccoon anymore. Now if it could magically reduce sound, it'd be an even cooler miracle...

Great fit and keeps room dark for baby

Easy to install and does what it is meant to do!!

These are a GAME CHANGER, helping not just with sleep but also heat control in our apartment. LOVE THEM.

They work as advertised.

My 3rd floor home office and master bedroom get morning and evening sun respectively so it gets warm and the AC runs a lot. I installed the portable sleep out in my home office and there is a noticeable difference in the temperature throughout the 3rd floor. It’s only been 24 hours. I think I’ll purchase some for my bedroom too. I think it will be a huge difference to my electricity bill.

Easy to install and great quality. Definitely keeps all the rooms so much cooler. Love that I can crack open the windows at night for air flow without disrupting the curtains

The curtains work as advertised, which is great! We bought two large to cover a large sliding glass door. I put them up every night and take them down in the morning. Not too bad since they’re pretty simple to install, and they beat the Alaskan midnight sun!

Excellent quality. Works well.

that's most of my reason for buying this curtain, is the suction cups. actually one just came off, but i had bumped it with the blinds, and it's been on there for months. i just ordered two extras because i like to open the window halfway, so i've been using one of these extras to keep the curtain flush halfway down the window.

Likely to buy again, happy initially, making sure there are no issues further out. Using for heat and light issues. Easy set up and use, really like that I'm able to move them through out the day to other windows to address heat issues as sunlight moves and intensifies during the day.
