"Many of us know it: cold feet in the evening that prevent you from falling asleep, or a tropical summer night that comes with restless sleep. The fact that body temperature and sleep are inseparably linked, is also evident from a scientific perspective. The right temperature at the right time is essential for good sleep. Dagsmejan’s sleepwear can support the nightly changes in body temperature and thereby naturally improve sleep."

Frustratingly loving it.

The comfort during sleeping is unprecedented, it doesnt crawl when I change sides, it stays very nicely around my ankles. It always makes me feel I'm wrapped in a cloud. Not sweating or shivering in them.

But because it's so silky smooth and stretchy it's a just a tiny bit annoying to put on. You have to extend your leg and pull up quit a bit before it goes over your feet. Plus its long enough to have ordered a size smaller, perhaps this would have solved my problem.

And unfortunatly the crotch tore up a bit, easily fixed but can't figure out when it happened.

I have it 2 years now, still massivly happy with it. In the winter I used to sleep in jogging pants but a lot of times it was just to hot. These pants regulate the temperature perfectly, and together with the shirt I havent had a sleepless night anymore because of the cold or warmth.

Truly worth every penny.

I just really wish they also made socks with this material.

Cant sleep without it.

I used to sleep in a cotton shirt, probably 15 years old, full of holes, can't remember why I still have it. In the summer it was horribly sweaty, in the winter it was horrible cold, but it was my designated sleeping shirt. Couldnt part with it.

Now I already own merino shirts for hiking but I was researching for a new one and at a certain point googling I came across Dagsmejan...what's this? sounds weird..."The world's most comfortable pajamas"...really? it's just a merino shirt right?

So because I'm a sucker for nice fancy things I thought, a designated merino sleeping shirt...ofcourse I buy one!

And holy moly am I glad that I did! I have it almost 2 years now. This shirt is like nothing else, it's silky smooth, so comfortable on your skin, it's a bit longer so during the night it's doesnt crawl up to your neck, in the summer it doesnt stick, in the winter it was warm enough. It's so light you hardly feel it. Plus it looks great, I often think about buying one for regular use.

And I can honestly say, you could probably wear it for a month and it still wouldnt smell.

Absolutely worth the money, you cry a bit when you buy it but after a day you already know it was worth it.
