Breathability: For better more natural sleep

Breathability is important for comfortable sleep

A breathable baby sleeping bags allows air and moisture to pass through. These are the qualities that help keep your baby’s body at the right temperature so they don’t wake up at night. The result is better, deeper and more relaxed sleep – for baby – and for you.

How does it work?

Thanks to their clever structure, wool fibers can absorb up to 35% of their own weight in moisture. The moisture goes into the core of the fiber, leaving the outside completely dry. Isn’t nature wonderful!

Unlike wool, polyester only absorbs up to 3% of its own weight. The moisture stays trapped between the fibers and your skin, leaving you feeling clammy.

Breathable Swisswool

Mother Nature has also provided wool fibers with millions of tiny little air pockets. The air pockets provide insulation. They keep the body warm when it’s cold and cool when it’s hot.

Down - breathable, but warmer and more insulating

The snowflake-like structure of down’s clusters means that it is actually mostly empty space. This allows the warm air to be trapped within the cluster, which is why down is such an excellent insulator. At the same time, down is also breathable, because when the sweat your body creates at night touches one of the cluster's hairs, part of that moisture is immediately transferred to any of the cluster’s other hairs. This moisture then dissipates throughout the day, when your duvet is no longer in contact with your body.

This is why you should shake out your duvet a couple of times when you wake up in the morning, as this shakes any clusters that have clumped together loose again. It’s also a good idea to let your down duvet air out on warm, dry days. This eliminates any moisture that might remain in the duvet and allows the down to circulate.

This is important because down’s great enemy is oversaturation - when wet or soaked, down loses much of its insulative power and breathability. Our down duvets are machine washable, but make sure to put a few tennis balls in the dryer so that the down doesn’t clump together when it dries.
