The sleep benefits
The sleep benefits
Keep the optimal temperature for sleep and get the sleep comfort and quality you need and deserve with the best pajamas for men:
- Lightweight thermo-regulation, 6x more breathable than cotton
- 4x better at moisture management: cooling you down with evaporative cooling, keeping you dry with moisture wicking powers
- 2x softer than cotton, feels like a second skin
"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, but if we get too cold we will shiver and our sleep quality suffers. 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." –dr Lutz Graumann, Phd & specialist in sports medicine, nutrition and chirotherapy

- JFJeff F.Verified BuyerReviewingLong sleeve top — NATTWELL™I recommend this productMy sleep type I'm often warm and sometimes sweatRated 5 out of 5 stars2 months agoBest adult pajames
I tend to get hot when I sleep, and a friend recommended this brand to me. I'm now a huge fan—I love their sleepwear! It's incredibly comfortable, and I no longer overheat at night. I'm also a big fan of the recovery sleepwear.
My wife is now a supporter as well!
In colder climates, the "Stay Warm" line is perfect.
Overall, I’m genuinely impressed and love their products.
Thank you!
