“As a woman that sometimes struggles with night sweats and fluctuations in the bedroom temperature, I welcomed the idea of pjs that are soft and comfortable. I’ve enjoyed sleeping without waking up due to excessive sweating or overheating. The fabric is very comfortable and soft and the style is flattering and works really well” –Dr. Funke Afolabi- Brown, triple board-certified sleep medicine physician

    "Thermoregulation is key for good sleep. To fall asleep and enjoy a deep, restorative sleep we need our body temperature to drop. I recommend Dagsmejan; their pajamas help us to cool down or warm up depending on our needs to sleep deeper for longer."

    Overall, one of the better sleep masks.

    I really like the fit and feel of this mask and the fabric is soft. The only reason I didn't give it 5 stars is because the cotton inner materials have a couple of little bumps in it that I can feel with my fingers though not when wearing it.
