1.0 TOG Baby Sleeping Bags – Perfect for 18–24°C Spring & Autumn Nights

If you're wondering what TOG sleeping bag is best for spring or autumn, the answer is 1.0 TOG. Slumbersac’s 1.0 TOG baby sleeping bags are specially designed for use in room temperatures between 18 and 24°C, offering the ideal balance of warmth and breathability for your baby or toddler.

Whether you need a sleeping bag for spring, a light baby sleeping bag for a well-heated nursery, or an autumn sleeping bag to get through those cooler mornings, our 1.0 TOG range is a practical, safe alternative to blankets — suitable from birth up to 10 years.

These mid-weight baby sleeping bags are ideal for transitional weather, giving your little one cosy comfort without overheating. The sleeveless design allows for airflow, while the secure fit helps reduce the risk of SIDS by eliminating loose bedding in the cot or bed.

Why Choose a 1.0 TOG Baby Sleeping Bag?

A 1.0 TOG sleeping bag is best used:

➤ When the nursery is kept between 18–24°C

➤ During spring and autumn months

➤ If your child often kicks off covers at night

If your baby sleeps in a heated home or struggles with temperature regulation, a 1.0 TOG baby sleeping bag provides just the right level of insulation — making it a year-round staple for many families.
