With a collar, but still cool: Dagsmejan's new classic pyjamas tested

With a soft collar and a decorative button placket (without real buttons), pyjama specialist Dagsmejan is expanding its design line. I tried out the sleep shirt.
If you know my articles on the topic of sleep, you already know that I am a self-confessed fan of sleepwear from Dagsmejan. Step by step, I have replaced my previous pyjama wardrobe. Simply because I felt and measurably - thanks, Apple Watch! - had more restful nights in the «functional sleepwear». - have more restful nights.
The Zurich-based company recently tried its hand at a new design. Until now, the fashionable variety of shirts and trousers was manageable. T-shirts were available with short or long sleeves, with a round or V-neck. Trousers were either short or long. The dominant colours were blue, grey and green.
A trend from the past
In contrast, the latest collection of shirts picks up on the trend towards classic designs. This means that the tops have collars and button plackets, or at least a hint of them. Sleep shirts were last really in fashion at the end of the 19th century. The gentleman of the world wore a two-piece combination of loose-fitting trousers and a shirt-like top, as can be read in an article from the Vienna Museum on the history of pyjamas. The new two-piece garment increasingly replaced the nightgown. In 1913, the «Prager Tagblatt» wrote about the advantages of the negligee for men:
Isn't it marvellous to be undressed and dressed at the same time?
And yes, even in 2025 it feels like that to me. If I were wearing my Dagsmejan top in dark blue, I'd have no qualms about opening the door to the postman early in the morning and acknowledging receipt of a parcel. Only my shorts would give away the fact that I had only just got out of bed. Because I don't wear long trousers.
For me, the most important advantage of the Dagsmejan pyjamas is the «Nattcool» technology. It's not new, the manufacturer has just changed the cut of the shirts. The fabric has - fortunately - remained the same. The blend of 92 per cent eucalyptus-based Microlyocell and eight per cent elastane guarantees the comfortable feel that I already know so well. According to Dagsmejan, the difference to pure cotton pyjamas can even be expressed in figures: The material is «twice as soft as cotton» and it is said to be eight times as breathable. I can't exactly feel the factor. But the fact that the Dagsmejan items dry much faster after washing than conventional pyjamas is definitely true.
A feeling like silk
So far I've only had the normal T-shirts. These are cut close to the body, so I don't feel any creases in the fabric or the very flat seams. Doesn't a collar and a button placket, even if there is only a hint of one, ruin exactly this advantage? After a few weeks of tested sleep, I give the all-clear: no, the shirt-style top also quickly transports me to the realm of dreams and lets me sleep at a good temperature. This is mainly due to the soft fabric, which feels almost like silk.
I deliberately chose a collar shirt in size M. This is because the back length of 74 centimetres is exactly the same as the previous T-shirts. The width of the M shirt is 113 centimetres, while the T-shirt in L is 110 centimetres. Too complicated to think about? Okay, the short version: the tops with collars are cut much wider and fit much looser.
Dagsmejan has adopted the offset shoulder seams and the lack of sewn-in labels from the T-shirts.
If Dagsmejan has not changed the fabric formula, I can make a valid statement about the longevity of the pyjamas as a long-time intensive user. Even after dozens of washes, my very first Dagsmejan Staycool pyjamas are still in good shape and still in use today.
In a nutshell
Classic cut, familiar coolness
Raider is now called Twix, but nothing else has changed. Do you remember this slogan from the advert? It's a bit like that with the new Staycool shirts from Dagsmejan. Nothing has changed with the fabric, because it has obviously proved its worth. But there is a new cut that will find its customers with significantly more width for the chest and stomach.
Pro
- No labels and annoying seams
- Familiar fabric quality for a good sleeping climate
- Shirt-like design looks a little more dressed up
- Indicated button placket and collar do not interfere with sleeping
Contra
- I'm missing a closer-fitting design in the range
