Summer is coming, and with it, warm nights... You're asking the question every parent asks: should I use a sleeping bag for my baby in summer?
The answer is yes! A good summer sleeping bag allows your little one to sleep peacefully and safely, without the risk of uncovering or overheating. At Baby Nuage, we have carefully selected the lightest, most breathable models that are gentle on babies' sensitive skin.
In this guide, we tell you everything: TOG, materials, sizes, safety criteria, and our favorite PAPATE products, the Made in France brand we distribute.
Why use a summer sleeping bag?
Unlike a classic blanket, the sleeping bag (or baby sleeping bag) stays in place all night. It prevents the baby from uncovering, reduces the risk of sudden infant death syndrome, and provides that comforting cocoon babies so desperately need.
In summer, when the room temperature often exceeds 22-24°C, a sleeping bag that is too warm can quickly become uncomfortable. This is where lightweight models specially designed for the warm season come in.
TOG: the heat index you absolutely need to know
The TOG (Thermal Overall Grade) is your best ally for choosing the right sleeping bag:
| Room temperature | Recommended TOG | Sleeping bag type |
|---|---|---|
| > 24 °C | 0.5 | Ultra-light (summer) |
| 22 – 24 °C | 1 | Light (spring/summer) |
| 18 – 22 °C | 2 to 2.5 | Mid-season |
For summer 2026, choose a TOG 0.5 or 1 sleeping bag. It is light enough so that the baby doesn't sweat while offering the softness of a cocoon.
Ideal materials for a summer sleeping bag
In summer, we primarily look for breathability and softness:
- GOTS certified organic cotton → our favorite material at Baby Nuage. Natural, hypoallergenic, ultra-soft, and respectful of babies' skin.
- Cotton gauze (double gauze) → the star of summer! Light as a cloud, it allows air to circulate perfectly and dries very quickly.
- Muslin → even more airy, ideal for the hottest nights.
We avoid synthetic materials that retain heat and prefer everything that is Made in France and organic, such as PAPATE creations.
How to choose your summer sleeping bag?
Here are the 5 essential criteria:
- The TOG (see table above)
- The material: organic cotton or cotton gauze
-
The shape:
- Sleeveless → better ventilation
- With open or closed feet depending on age
-
The size:
- 0-6 months / 6-12 months / 12-24 months / 24-36 months (always take the next size up so that the baby has room to move their legs)
- Safety: secure zipper, no hood, reinforced seams, OEKO-TEX or GOTS certification.

Tips for using the sleeping bag in summer
- Keep the room between 18 and 24°C (fan + blackout curtains if needed).
- Dress baby lightly underneath: short-sleeved bodysuit or nothing at all depending on the temperature.
- Regularly check the baby's neck: if it's damp, remove a layer.
- Wash the sleeping bag at 30-40°C to preserve the softness of the organic cotton.

A good summer sleeping bag is not a luxury; it's a real ally for your little one's sleep... and yours!
