    "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."

    Very nice shorts

    I bought this at the same time as the matching shirt. It is very comfortable and I don’t even notice it when sleeping. I am 172 cm and 65 kilograms, and this fits perfectly.

    Perfect

    This shirt fits me perfectly and feels amazing on the skin. I am 172 cm and 65 kg and a small fits me correctly. I especially like that the shirt is long, so it doesn’t write up when sleeping.
