    "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."

    Great pants

    The mask must be an absolute blessing. My girlfriend travels a lot by plane and night buses. In combination with your in-ear noise canceling headphones, you can sleep perfectly anywhere as not a bit of light penetrates.

    Everything it claims to be!

    I am very picky about eye masks! A lot of them smash your eyeballs, or let light in, or are heavy. This one you can sleep in (on your side) you can adjust the eye cups as well as the size around your head. This is pricey but worth it! I'm buying another! Material is very comfortable!
