Dagsmejan—Sleepwear reinvented

Dagsmejan—Sleepwear reinvented The world's most comfortable sleepwear. Light, breathable and super soft. Introducing Dagsmejan—sleepwear reinvented.

After a good night’s sleep we feel refreshed and energised, ready to make the most of each day with a clear mind. That’s why we developed Dagsmejan sleepwear, combining the best of nature and science for improved sleep quality. Sleep is one of the most powerful tools to a better tomorrow—you can literally sleep your way to be being happier, healthier, smarter and faster. Yet sleep problems are bec

oming epidemic, impacting not only our nights but also our days. Many factors influence our sleep, recent research show that one very important, but often overlooked, one is to keep our body temperature in the right climatic zone throughout the night. Our temperature often shifts when we sleep however due to for example our exercise habits, food and health. More surprisingly perhaps, did you know that the more intensely we dream, the more we sweat? Whilst there has been a functional revolution in sportswear with innovative fabrics and construction techniques, we spend a third of our lives in one of the least innovative garments around – the same type of pyjamas that were used 50 years ago. By taking the insights from high performance sportswear and adapting them to our body’s physiological sleep needs we have reinvented sleepwear for a good night and a great day.

Great sleepwear starts long before the first stitch.

It begins with carefully selecting fibres that work with your body throughout the night.

That's why both Stay Cool and Stay Cool Air are crafted from eucalyptus-derived TENCEL™, chosen for its exceptional softness, breathability and moisture management. From there, each collection is engineered with a different purpose—whether you need balanced cooling comfort or maximum airflow during the hottest summer nights.

Because better sleep isn't one-size-fits-all.

Swiss nights have their own rhythm.

Longer evenings. Fresh mountain air. A slower pace. Moments that help the body unwind before the night begins.

As a Swiss brand, our roots continue to shape how we think about sleep: combining innovation, natural performance fibres and science to create sleepwear designed around how the body actually rests.

Because better sleep often starts long before bedtime.

Happy Swiss National Day!

Some nights your body simply struggles to cool down.

Heat and humidity can continue building up while you sleep, making rest feel warmer, heavier and less restorative.

Stay Cool was developed to accelerate heat and moisture release through breathable eucalyptus-based fibres, creating cooling comfort for warmer nights and hot sleepers.

For cooler, more stable sleep conditions from the moment you fall asleep until morning.

Warm nights call for a different kind of comfort.

Not maximum airflow or extreme cooling, but a sleep environment that feels cooler, calmer and more balanced throughout the night.

Stay Cool was developed to help regulate excess heat and maintain cooling comfort during warmer sleep conditions, so you can enjoy more restful sleep all summer long.

Because summer sleep should still feel deeply restorative.

Have you ever noticed that you rarely sleep quite as well while travelling?

Even when the bed feels comfortable, unfamiliar surroundings can make your body more sensitive to things like temperature, airflow and physical comfort throughout the night.

That's why breathable sleep conditions become especially important during summer travel.

Stay Cool Air was developed to maximise airflow and lightweight comfort, helping create cooler, lighter sleep conditions in warmer environments.

Because your body rests differently when everything around it feels unfamiliar.

Warm summer nights can change how sleep feels.

Heat, humidity and limited airflow often make sleepwear feel heavier and less comfortable as the night goes on, especially while travelling or sleeping somewhere unfamiliar.

Stay Cool Air was developed with maximum breathability in mind, helping create lighter sleep conditions during warmer nights.

Designed to feel exceptionally light, dry and almost unnoticeable on the body.

Because cooling sleepwear should never feel heavy.

Warm nights often feel heavier on the body.

Even when you're physically tired, trapped heat and humidity can make sleep feel lighter, less comfortable and less restorative.

That's exactly why Stay Cool Air was developed. Designed for maximum breathability, it helps release excess heat and maintain a lighter, cooler sleep environment throughout the night.

Because better sleep starts when your body can finally cool down.

Summer sleep isn't always the same.

A warm evening in the city, changing travel conditions or intense summer heat can all affect how your body experiences sleep.

That's why different sleep environments call for different sleep solutions.

Balance was designed for changing temperatures and travel conditions.

Stay Cool provides cooling comfort on warm nights.

Stay Cool Air offers maximum breathability when heat feels heavier and harder to escape.

Because better sleep starts with understanding the conditions around you.

Which sleep environment sounds most familiar to you?

Sleep often feels different away from home.

Warmer rooms, unfamiliar surroundings and changing airflow can all make sleep feel lighter and less restorative.

Because better sleep should travel with you.
