The Slumber Cloud Cotton Duvet Cover uses Outlast technology to absorb and release heat, keeping sleepers comfortable. It suits hot sleepers and those who want a breathable, soft cotton cover. Its standout trait is active temperature regulation, not just passive breathability.
Why Temperature Regulation Matters
Body heat can trap under a duvet, causing night sweats. Standard covers only breathe passively. Active temperature regulation uses phase change materials to absorb excess heat. This helps maintain a stable microclimate. Hot sleepers often find this tech beneficial.
Cotton Percale vs Sateen
Percale is a plain weave, giving a crisp, matte feel. It's breathable and gets softer with washing. Sateen is smoother and silkier but can trap more heat. For cooling, percale is usually better. The Slumber Cloud uses percale, aligning with its cooling intent.
How to Choose the Right Size
Measure your duvet insert before buying. The cover should be slightly larger to accommodate the insert. Slumber Cloud offers Twin, Full/Queen, and King. Full/Queen fits both full and queen inserts, but check dimensions. A snug fit prevents shifting.
Caring for Your Duvet Cover
Machine wash cold on gentle cycle. Tumble dry low, and remove promptly to reduce wrinkles. Avoid bleach and high heat, which can damage the Outlast fibers. Owners report it dries quickly. Ironing is possible on low if wrinkles bother you.

Buy it if you're a hot sleeper who wants a natural cotton cover with active cooling tech.
Skip it if you sleep cool or prefer a sateen finish, as the percale is crisp and the tech may be unnecessary.
Questions before you buy
Does the Slumber Cloud duvet cover really keep you cool?
Yes, based on owner feedback and the Outlast technology. It absorbs excess heat when you're warm and releases it when you cool down, helping regulate temperature.
What is Outlast technology?
Outlast uses phase change materials that absorb, store, and release heat. This helps maintain a comfortable skin temperature, reducing overheating.
Is the Slumber Cloud duvet cover soft?
It's made of cotton percale, which is crisp at first but softens with washing. Many owners find it comfortable against the skin.
Can I use it without a duvet insert?
Yes, but it will be thin. It's designed to cover a duvet insert, so using it alone may not provide warmth.
How do I put on the duvet cover?
Turn the cover inside out, attach the corner ties to the insert, then flip right side out. The hidden button closure makes it easy to secure.
Is the Slumber Cloud worth the price?
If you struggle with night sweats, many owners say yes. The active cooling tech is more effective than passive covers, but if you sleep cool, a standard cover may suffice.
Can I machine wash and dry it?
Yes, machine wash cold and tumble dry low. Remove promptly to minimize wrinkles. Avoid high heat to protect the Outlast fibers.
