Spring & Summer Baby Sleeping Bags
In spring and summer, mild to hot months arrive, and the temperatures outside as well as the room temperatures steadily rise. A cozy warm autumn or winter sleeping bag with sleeves is no longer necessary. Instead, it is now time for a light, breathable sleeping bag: The Sterntaler spring and summer sleeping bags invite your baby to sleep and dream, as they are not only gentle on the skin and air-permeable, but also light and soft.
Sleeping bags made of cotton are especially suitable for a pleasant sleeping climate, as they are breathable and temperature-regulating, so babies do not sweat while sleeping. Sterntaler sleeping bags are also very easy to care for, as you can simply wash them in a normal cycle at 40°C.
Light Sterntaler Sleeping Bags – Developed with a Nurse
With our high-quality Sterntaler spring and summer sleeping bags, we focus on maximum comfort and safety for your baby. Our sleeping bag concept therefore not only meets the safety standards of the European standard DIN EN 16781 for textile articles for infants and toddlers, but was also developed and optimized together with the family nurse and sleeping bag expert Tina Rapp.
This way, you and your baby benefit from the following practical features and advantages:
✓ Sleeping bags in very small sizes
For the smallest ones: Sterntaler sleeping bags are available from a size of 44 cm and are suitable for preemies and small newborns.

✓ Comfortable intermediate sizes
With sleeping bag sizes between 44–110 cm, our sleeping bags accompany your child from birth up to 6 years of age. And since your baby should always grow out of the sleeping bag, not into it, we also offer our sleeping bags in the convenient intermediate sizes of 80 and 100 cm.
How to calculate the right sleeping bag size for your baby can be found in our article “Baby Sleeping Bag Size”.
To the article✓ Practical cable opening
If your little treasure requires medical care, the care cables can be guided through a small side opening, so your baby can safely and sweetly dream thanks to this feature of the Sterntaler sleeping bag.
✓ Ideal sleeping climate
In the production of our sleeping bags, we as a brand rely on HYDROCOOL® microfiber lining, which has a temperature-regulating effect: In warm temperatures, it provides cooling, and in cool temperatures, it keeps warm. Due to the balancing properties of the material, the sleeping bag can be perfectly used
for summer and winter.

✓ Integrated cuffs on the inner sleeping bag
The light Sterntaler inner sleeping bag with long sleeves has protective cuffs at the sleeve ends, so your darling is safe from scratches and cold hands. In cooler temperatures, this inner bag can also be combined with the Sterntaler baby sleeping bag (0.5, 1.5 or 3.5 TOG; with armhole) as an outer bag.
✓ Comfortable 2-way zipper
The Sterntaler summer sleeping bags are equipped with a practical 2-way zipper, which makes changing diapers and dressing or undressing much easier. This means the wildly kicking legs of your baby are no longer a problem.
✓ High-quality muslin sleeping bags
Some of our Sterntaler muslin sleeping bags are made of 100% cotton (organic) and are especially suitable for very warm summer nights and days due to their air permeability. The soft muslin of these summer sleeping bags also wonderfully cuddles gently against delicate baby skin.
Which Baby Sleeping Bag for Summer or Spring: What is Important?
● Right sleeping bag size
The most important criterion for a baby sleeping bag – no matter the season – is the size. Whether in pear shape or in a modern straight cut: Our baby sleeping bags fit close to the body in the chest area, ensure good air circulation in the baby's leg area, and offer enough freedom of movement to kick and stretch the legs. The golden rule for the ratio of body length to sleeping bag size is: Grow out, not grow in! We are happy to advise you further in our article “Baby Sleeping Bag Size”.

● TOG value for the ideal sleeping temperature
Besides the right size and sufficient freedom of movement, the term TOG value sooner or later comes up when it comes to baby or child sleeping bags. The TOG unit measures the thermal resistance of textiles – the higher the TOG value, the warmer the sleeping bag.
Our spring and summer sleeping bags have a TOG value of 0.5–1.5 TOG.
Warmer sleeping bags for the cooler months are available in TOG values of 2–3.5 TOG. If you have questions about the TOG value, you can find more information in the article “What is the TOG value?”.
Tip: If it is rather cool at night, you can still use the light sleeping bag and simply dress your little one in a warmer romper or cozy pajamas under the sleeping bag. More information on how to dress your baby in warm summer nights or even in a winter sleeping bag can be found in our article “Baby Sleeping Bag – What to Wear Underneath”.
