    "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."

    Oh my gosh! The best sleepwear ever!

    I bought this sleepshirt after having slept for years in cotton nightgowns. I decided to try it and love it! The MOST comfortable sleepwear I have had ever worn. I’m ordering more for myself and looking to introduce my friends and family. I hope they last a long time.

    Absolutely love these pants!

    These are undoubtedly the most comfortable pajama bottoms I’ve ever worn. Soft and sleek. And they dry in no time. Perfect travel jams!

    So comfortable

    Definitley temperature controlling - had the best cool sleep in months and that is with temperatures outside nearing 35C. We do not have air conditioning - this made my sleep that much more comfortable
