    "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."

    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

    Best but a twist

    Love this sleepshirt. Truly the best feel and comfort. My one issue is that after the first wash (following directions to the letter) the sleepshirt has twisted leaving one seam a bit more to the front and the other a bit more to the back.
