DEVELOPED WITH OUR EXPERTS

RESEARCH BASED, SCIENTIFICALLY PROVEN

"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. 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."

Eye mask

This is a good eye mask which is very comfortable to wear and the material feels lovely and soft. My head doesn’t feel hot when wearing it. I’ve only given it 4 stars as it’s a little large on me

Not adjustable, too big for me and too small for my husband

We ordered two, one for me and one for my husband, as we like the softness of materials from this company. The mask is too big for me (by far) and too small for my husband.

You need to make them adjustable!
