22-06-2020Absolut super! War zu Beginn etwas skeptisch ob der dünne Schlafsack meinen kleinen Mann auch wirklich warm hält. Aber nun nach einigen Wochen in ständiger Benutzung, auch untertage in der Nonomo oder im Kinderwagen, kann ich dieses Produkt uneingeschränkt weiter empfehlen. Endlich kein verschwitztes Baby mehr. Er schläft dadurch auch deutlich ruhiger und der Schlafsack hält schön warm.
Würde und werde ich wieder kaufen. -

The benefits of a summer sleeping bag for your baby, and why your child should use one
Children often move around a lot in their sleep. Their dreams are more vivid than adults', as they process the day's exciting events and develop mentally and physically while they sleep. They also refine their motor skills by wriggling around or turning over.
Because of this increased movement, though, they also tend to sweat more, especially on warm summer nights. Excessive sweating can not only wake your child up at night and keep them awake, but can also cause them to push off their covers, leading to a rapid drop in body temperature from the sweat.
When your child sleeps soaked in sweat and without covers, their immune system can weaken, making them more likely to fall ill. That's why sleeping bags are ideal for children in summer, as they help regulate temperature more effectively.
Sleeping bags can't be pushed off or slip like covers can — they keep your child comfortably warm no matter their position. They allow plenty of freedom of movement during sleep, but can't be pulled over the head like covers or pillows, so you don't need to worry about overheating.
What to consider when buying a summer sleeping bag for your baby
There's a wide choice of children's sleeping bags out there, but they differ in features and safety. So what should you look out for when buying a new sleeping bag for your child?
The right material for summer
When buying a summer sleeping bag for your baby, the material matters a great deal. Parents should make sure the sleeping bag is made from quality, breathable materials. It's also important that it absorbs moisture well, so your child stays comfortably dry and warm at night.
Pure natural materials are best suited to summer sleeping bags, since cotton is known for its excellent breathability and moisture absorption. The material should also be very soft, to feel gentle on baby's delicate skin and give them a sense of security.
Zips and buttons
Sleeping bag fastenings need to meet certain safety requirements and shouldn't bother the child. Long zips are the most practical, since they let you change a nappy without having to remove the whole sleeping bag.
Neck and arm opening size
The neck opening shouldn't be too wide, so the child doesn't slip down inside the sleeping bag and lose too much body heat. The same goes for the arm openings. That said, if they're too tight, there's a risk of chafing or restriction.
Our summer sleeping bags meet all of the criteria mentioned above, as you can see on our product description pages.
Our Zizzz summer sleeping bag is made from 100% organic cotton
Our summer sleeping bag is made from certified knitted organic cotton, extremely soft on the skin. It gives your child a sense of security and can help them sleep for several hours at a stretch.
Cotton absorbs moisture well and allows for better air circulation. This prevents overheating inside the sleeping bag, which is especially important in summer. Cotton also helps regulate temperature and has a cooling effect in warm weather.
Curious about warmth levels across seasons? Read our guide to TOG ratings and the evolution of baby sleeping bags.
Our organic cotton is also durable and hard-wearing, keeping your child covered all night long. Unlike our four-season sleeping bags, our summer sleeping bag consists of a single layer of knitted cotton, with no filling.
No chemical pesticides are used to grow our organic cotton. Our cotton is gentle on sensitive skin.
