    "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 pajamas help us to cool down or warm up depending on our needs to sleep deeper for longer."

    Bought this for my wife and she loves it!

    My wife is always warm, and so she has been on a search for a long time to find sleepwear that was comfortable. She was a bit skeptical about the purchase, but she loves the fabric, fits well, and the garment has made her sleep better.

    Lightweight perfect sleep shorts

    These shorts were the perfect compliment to the matching top. I'm XL/more plus size, I wish they were a tad longer, but overall, I'm happy with them. They help keep me cool at night and feel soft on my skin.
