“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.

    "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!
