DEVELOPED WITH OUR EXPERTS

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."

Sweaty Betty

Love these pants! I could not sleep well without them. Menopause has me sweaty every night and these pants wick away the moisture so effectively I’m not going from sweating to freezing and needing to change in the middle of the night. The best, really!!
