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."

—Lutz Graumann, Phd & specialist in sports medicine, nutrition and chirotherapy

Best PJs ever.

These are the best sleepwear I’ve ever had. Wasn’t sure if they could deliver on the promises. I’ve not had them long so I can’t speak to wear but they are very comfortable and sleep cool.

Highly recommend

Really love this set! Performance meet comfort when it’s as best! Maybe more expensive than regular sleepwear but worth it in my opinion! But quality and fitting is then also far above normal!
