The Science Behind a Great Night’s Sleep—NATTWELL®

Extensive research allowed Dagsmejan to enhance the MicroModal fibre—the core remains moisture absorbing, while the outer layer is adapted to make it water resistant and to repel moisture. This is what makes Nattwell™ fabric revolutionary moisture management and temperature regulation properties. The result? Moisture wicking sleepwear that help you stay longer in the ideal climatic zone for a deeper and better sleep.

Sustainable softness from beechwood

Nattwell™ fabric is based on a natural fibre called MicroModal that is both soft on the skin and exceptionally ecological. The fibre is extracted from beech wood, using Edelweiss® technology, a production process that is low on energy usage and other resources. All steps of the production process of Dagsmejan sleepwear are Oekotex certified to ensure that Dagsmejan take care of not only our customers but also the environment.

Designed for a great night's sleep, every night

By assessing our nightly temperature and sweat patterns, as well as sleep positions and movements, Dagsmejan have been able to design a unique collection of sleepwear optimized for sleep.
