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

Simply a blessing!
I have now bought my second sleep mask. The first one was for my son, who lives in hot Brazil, and he absolutely loved it. My daughter, who has to travel a lot, was given one as a gift and is also full of praise.
