Merino wool sleepwear—the all year sleep magic

Merino wool sleepwear—the all year sleep magic

Merino wool pajamas has been proven to help you sleep deeper and longer by regulating your temperature and moisture to keep you at the right degree the whole night.

Researchers from Australia have found that sleeping in merino wool pajamas instead of cotton can give you up to 15 minutes’ extra sleep. In today’s time stretched world those are precious minutes to wake up with more energy.

How do merino pajamas help you to stop counting sheep and start sleeping better? Researcher Dr Paul Swan, from the University of Sydney, said:

"Maybe it is not a coincidence because wool regulates your body temperature far better, keeping you in what is known as 'the thermal comfort zone'. You therefore not only fall asleep quicker, sleep longer, but also have deeper, better quality sleep.”

The unique properties of merino wool make it the perfect all-year sleep companion.

Merino wool sheep—braving the extremes

Merino wool sheep live in extreme environments where the temperature varies from hot hot hot to freezing cold. To survive in these temperatures the merino sheep rely on the natural engineering of their wool.

The merino wool coat is warming in the freezing cold;

The natural structure of merino wool creates insulating air pockets, trapping more air than any other fibre and building a defense against the cold. This keeps the merino wool sheep warm even when the temperature plummets to -10°C.

And cooling in the heat;

Super lightweight and breathable, the merino’s sheep’s summer coat keeps cool in temperatures of up to +30°C. In the scorching sun not overheating is vital for survival so nature has given merino sheep superior thermo-regulation abilities.

Nature’s luxury temperature regulation

This gives merino pajamas exceptional thermo-regulation properties for the best sleep comfort regardless of the season.

Merino wool is nature's wearable thermostat. Nattwarm™ fabric helps to keep you warm when it’s cold and cool as you heat up.

When the nights get hotter, the fibers absorb your body’s moisture vapors and evaporate them outside the sleepwear– keeping you cool and comfortable. If it's cold, however, the moisture vapors condense inside the fiber, giving off heat to keep you comfortably warm. This makes it the ideal fibre for a winter pajamas.


Merino wool pajamas keep you so fresh you can wear them night after night. It absorbs all odor molecules to only release them when your sleepwear is washed. Even on the hottest nights, you will still feel fresh.

Your merino wool sleepwear won't smell like your cotton sleepwear. As an added benefit, you don't have to wash it as often, you can just air it out if you feel the need.
