The purpose of the sleeping bag is to keep a baby warm during winter, as
babies tend to kick their blankets off.
The Baby Sense Slumber Sac is made of 100% pure cotton, and both the fabric and fillling are breathable to prevent overheating.

The Slumber Sac fits a baby from 5 to 18 months, keeps the baby warm and allows ease of travel with a unique slot for the seatbelt. There is no need to unwrap the baby to remove them from the car seat.
