    "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."

    Works as described

    The T-shirt is lighter than expected, but it is super comfortable and does a great job of regulating temperature while sleeping.

The Dagsmejan men's cooling sleep shorts help you to sleep cool even if you are a hot sleeper or if the ambient temperature is rising. By combining exceptional breathability with evaporative cooling and superior moisture wicking abilities excess heat is released. As a result the cooling pajama shorts formen help you to stay cool for a more restorative sleep. Ideal as summer pajama shorts for men but great all year around for hot sleepers.
