      "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."

      Very comfortable and cool.

      I enjoy the coolness of this top and love the material. For a large it is a little snug. Would get an XL next time, and try the pajama top button down. Frankly I still get warm and remove it during the night… though glad to have it.

      Best t shirt for sleeping

      I’ve used this shirt for 3!weeks and it has helped reduce my sweating immensely. My wife hates washing it every night so I have to buy more.

      Dear John,
      thank you for your great review.

      We are happy to hear your feedback, that your Dagsmejan sleepwear helps you to regulate your body temperature.

      Our collections are equipped with antibacterial & anti-odour properties.
      This means that this fabric still feels pleasantly fresh even after several nights of wear.
      You can also simply air the items on a hanger by an open window and do this for several days in a row without having to wash them.

      Best wishes and we hope to see you again soon.
      Your Dagsmejan team
