    "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."

    Felt Great but Fit was Wrong

    These pj's felt so comfortable but when I tried the Medium on, it was very tight and form fitting. I thought I had ordered the right size but was completely off. I am normally a size 12 and medium but if I bought again I would have to order the XL. I unfortunately had to return it. I am worried to try another size because I do not know how it would fit and don't want the hassle to return again. I wish they were sold in more stores so that I could try before I buy.
