“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."

    perfect

    I love this so much I repurchased. Truly a cooling design and fabric, and flattering on. It will pack up very small for travel, too. Nice to have something that makes me feel good during this challenging phase!

    Love it but a little short - and I'm short!

    Love the fit, quality and comfort but it is very short. I'm surprised because I am only 5' 4" and most things are never too short on me. A tall person would find this VERY short. Wished it was a few inches longer.

    The best sleep shirt

    This sleep shirt is light, soft, silky and cool. It feels so wonderful and keeps me from overheating. I refuse to wear any other pajamas now that I have experienced this Nattcool shirt. Seriously—I had to order more colors because nothing compares to how comfortable and cool this feels.
