FAQs

Slumber Cloud products are designed to help manage heat and humidity build up. It is not an air conditioner with a set temperature degree, but it will react to your temperature all night long to reduce heat build up and manage temperature swings.

The Stay Cool Sleepwear generally fits true to size. We don't recommend sizing up or down from your standard sizing.

With 8% Lycra, the fabric does have some stretch, ideal for sleeping and lounging in!

The premium fabric has a super soft athletic hand-feel, with a little stretch to the fabric.

Looove the Stay cool Shorts !

"I ordered the shorts together with the Stay cool V neck top in color mist. The fabric is amazing as it feels cooling on the skin but more importantly , it helps stay cool t/o the night. No more waking up in middle of night with feeling hot & night sweats . BTW, color is nice &’ the fit of both top & bottom is very good. I have to admit that I started off with the performance matress pad a month ago that alrdy made a difference with feeling much cooler overall at night. Then I got this Stay cool PJ set which I also loved . And finally I ordered the essentials sheet set & essential duvet cover to have the complete package. Now I sleep like a baby 🙏. I highly recommend the Slumber cloud product line. The prices are on the higher side but it does so much more than your regular bed sheets. For me , it was a game changer."

Love this sleepwear...will buy more!

"So far it's fantastic! However, it is winter....so cooler in my house anyway. But I love the sleepwear so far. Very comfortable and I haven't woken up once sweaty! Of course, I also purchased the bedding too. So it's all working together, I suppose. But love it thus far."
