Spring & Summer Baby Sleeping Bags
In spring and summer, mild to hot months arrive, and both outdoor and indoor temperatures steadily rise. A cozy warm autumn or winter sleeping bag with sleeves is no longer necessary. Instead, it’s time for a light, breathable sleeping bag: Sterntaler’s spring and summer sleeping bags invite your baby to sleep and dream, as they are not only gentle on the skin and breathable, but also light and soft.
Sleeping bags made from cotton are especially suitable for a comfortable sleeping climate because they are breathable and temperature-regulating, so babies don’t 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 not only meets the safety standards of the European DIN EN 16781 norm for textile articles for infants and toddlers but was also developed and optimized together with 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 tiniest: Sterntaler sleeping bags are available starting at a size of 44 cm and are suitable for preemies and small newborns.

✓ Comfortable intermediate sizes
With sleeping bag sizes ranging from 44–110 cm, our sleeping bags accompany your child from birth up to 6 years old. And since your baby should always outgrow the sleeping bag rather than grow into it, we also offer our sleeping bags in 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 one requires medical care, the medical cables can be guided through a small side opening, allowing your baby to sleep safely and sweetly thanks to this feature of the Sterntaler sleeping bag.
✓ Ideal sleeping climate
In the production of our sleeping bags, we use HYDROCOOL® microfiber lining, which has a temperature-regulating effect: it provides cooling at warm temperatures and keeps warm at cooler temperatures. 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 lightweight Sterntaler inner sleeping bag with long sleeves features protective cuffs at the sleeve ends, keeping your little one 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 armholes) as an outer bag.
✓ Comfortable 2-way zipper
Sterntaler summer sleeping bags are equipped with a practical 2-way zipper, which makes diaper changes and dressing or undressing much easier. This means your baby’s wild kicking legs are no longer a problem.
✓ High-quality muslin sleeping bags
Some of our Sterntaler muslin sleeping bags are made from 100% organic cotton and are especially suitable for very warm summer nights and days due to their breathability. The soft muslin of these summer sleeping bags also gently hugs delicate baby skin.
Which Baby Sleeping Bag for Summer or Spring: What’s Important?
● Right sleeping bag size
The most important criterion for a baby sleeping bag—regardless of the season—is the size. Whether pear-shaped or in a modern straight cut: our baby sleeping bags fit close to the body around the chest, ensure good air circulation around the baby’s legs, and offer enough freedom of movement for kicking and stretching the legs. The golden rule for the ratio of body length to sleeping bag size is: Outgrow, don’t grow into! 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 discussing 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 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’s 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 on warm summer nights or even in a winter sleeping bag can be found in our article “Baby Sleeping Bag – What to Wear Underneath.”
