    "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."

    helps stay cool

    I really like these night dresses for the summer months. I get night sweats and these really help. Would say is lightly on the short side. Very comfortable though.

    LOVE this piece to sleep in.

    I love the material and the fact that I do not get as hot at night when I wear my slip dress.

    I love the shorter length as well.
