The science behind a great night's sleep

NATTCOOL™ Technology

NATTCOOL™ fabric has been developed to offer you the ultimate cooling sleep comfort by combining extraordinary breathability with a dual moisture management approach. The result? The ultimate lightweight, cooling pajamas. 


Natural fibres with cooling super powers

NATTCOOL™ is 8x more breathable than cotton as millions of nano capillaries lead excess heat away from the skin. If you start to sweat parts of the sweat is absorbed in the core of the fibres cooling you down through evaporative cooling. Thanks to the extraordinary fast drying times and the inherent moisture wicking properties of NATTCOOL™ you never feel wet.

NATTCOOL™ has shown exceptional moisture management and breathability compared to other natural fibres such as cotton and bamboo as well as synthetic fabrics. That's what makes it the most cooling pajamas you can imagine!


the best sleep temperature

Keep the best temperature for sleep

If we become hot at night our sleep suffers, in particular our deep sleep phases. Sweating at night while sleeping can lead to discomfort and disturbances. By staying in the ideal climatic comfort zone we can sleep deeper for longer. That's the difference Dagsmejan's cooling sleepwear makes. 


Designed for cool sleep

Pajamas that keep you cool

By assessing our nightly temperature and sweat patterns, as well as sleep positions and movements, we have been able to design a unique range of clothing optimised for sleep. Dagsmejan's collection of cooling sleepwear is designed to  ensure that you never overheat, even as the temperature rises.
