“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 pyjamas help us to cool down or warm up depending on our needs to sleep deeper for longer."

    Fantastic for temperature regulation.

    The t-shirt is comfortable and fits well, I chose my normal size. The material is fantastic. I sleep uncomfortably warm and often sleep without pyjamas. This is better, it really helps with my temperature regulation and I wake up less often in the night.

    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!
