Temperature

Stop The Sweat

An exceptionally high QMax score for an instant, cool-to-the-touch sensation, paired with an ultra-breathable, lightweight knit, makes even the hottest summers feel like spring.

FAQ
Questions, answered honestly.
How do SHEEX sheets actually cool you down?

Our performance knit pulls moisture from your skin and disperses it across a larger surface area, allowing heat to evaporate faster than traditional cotton. The result: a consistently cool sleep surface.

What's the 60-night guarantee?

Sleep on your SHEEX for 60 nights. If they aren't the most comfortable sheets you've ever owned, we'll refund every dollar, no questions asked.

How do they hold up after washing?

Unlike cotton that softens then breaks down, our performance fibers retain their softness and shape for years. Machine wash cold, tumble dry low.

Will they fit a deep mattress?

Yes. Our fitted sheets stretch comfortably over mattresses up to 18 inches deep, including hybrid and pillow-top constructions.

Nightfall fitted sheet

"These sheets are even better than the artic brand. And night sweats have improved. Wish the set was more affordable"

— Robbie H. (5/5)

Love this new line!

"It’s a great mix of the performance and midnight label. Silky enough, not too slippery or chilly like midnight label. A good compromise for my husband who likes the original performance, and me who likes midnight label! A new favorite. It will seem like it’s not going to fit the mattress, but it will! This thing stays in. Stays taught but stretchy on a purple mattress 3."

— Anastasia (5/5)

Cool

"Highly recommended"

— Caroline C. (5/5)

A Gift for my son

— Ellen N. (5/5)

Fabulous
