RESEARCH BASED, SCIENTIFICALLY PROVEN

"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."

Soft and comfortable

This is my second nightie as the quality fit and comfort of this nightwear is exceptional. It works to keep me cool and is so soft I would wear it all day if I could. Highly recommend and will be buying more.
