DEVELOPED WITH OUR EXPERTS

RESEARCH BASED, SCIENTIFICALLY PROVEN

"Thermoregulation is key for a good night's sleep. To fall asleep and to enjoy a deep, restorative sleep we need for our core body temperature to drop. That is why I recommend sleepwear by Dagsmejan; they help us to cool down or warm up depending on our needs so that we can sleep deeper for longer."

—Lutz Graumann, Phd & specialist in sports medicine, nutrition and chirotherapy

Comfortable but ill fitting at neck

Like I wrote above, the sleeping tshirt is comfortable, but the fit at the neck is very poor.

Great mask

I like the way it fits. The nightgown, however is the wrong size. I accidentally ordered an Xsmall instead of a X-Large. I received this package the day I was moving. It has never been worn, tags are still in place. It has only been out of the box one time. I would really like to exchange it for my size. Please advise.

Dagsmejan

Dear Patricia. Thank you for your great feedback. We thank you for the time you have taken to write your review and are happy to hear the fit of the garment has met your expectations. Our sleep comfort guarantee is 14 days as of receipt of the goods. Since your Sleepshirt is however unworn and has all tags in place, we are more than happy to make an exception for you and can replace it with another size. Our Support Team will email you the return steps today—your Dagsmejan Team.
