  • Don't overheat, 6x more breathable than cotton
  • 4x better than cotton at drawing night sweat away from the skin

"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

    Best mask ever!

    Used this for a trip to Alaska this summer. With over 22 hours of daylight, this mask was a wonder! I really like this mask as the cushions around the eye sockets keep the mask off of my eyelids, which for me is a big deal. Very comfortable when laying on my sides or my back.

    perfect sleep mask

    I've loved this mask for years. I ordered a new one because I left my previous one in a hotel. Very soft and darkens very well. 1 star deducted because the shipping costs are not automatically adjusted: a mask could be sent in a thin envelope much more cost-effectively.
