The sleep benefits

Blocking out 100% of light, the blackout sleep mask has fully adjustable eyecups for perfect coverage and an easily adjustable velcro strap to fit any head size. Sleep better in a natural and sustainable way.

"Thermoregulation is key for a good night's sleep. To
fall asleep and to enjoy a deep, restorative sleep we need for our core body temperature to drop, but if we get too cold we will shiver and our sleep quality suffers. That is why I recommend sleepwear by Dagsmejan; they help us to cool down or warm up depending on our needs so that we can sleep deeper for longer." –dr Lutz Graumann, Phd & specialist in sports medicine, nutrition and chirotherapy

Frequently Asked Questions

What is a blackout sleep mask, and why should I use one?

How do I clean and maintain my blackout sleep mask?

For best results, hand wash the mask gently with mild detergent and let it air dry. This keeps the blackout fabric soft and effective for a long time.
