    "Thermoregulation is key for good sleep. To fall asleep and enjoy a deep, restorative sleep we need our body temperature to drop. I recommend Dagsmejan; their pyjamas help us to cool down or warm up depending on our needs to sleep deeper for longer."

    Just what I was looking for!

    Because I tend to sleep hot but wanted something covering my legs when I'm up and about first thing in the morning, I took a chance on these. For decades, I have slept in boxers and a tank, but these are much more comfortable and feel luxurious. I tend to be thick through the middle and was glad to find that the waistband doesn't cut me in half. Wish I had discovered them sooner!

    Lives up to it billing...

    My wife is for all intents and purposes bedridden. She LIVES in her sleepwear. Having sensitive skin, these are her sleepshirts of choice (she has three)...s
