Are you worried about which weight baby sleep bag to use and whether your baby will be too hot or cold while sleeping?

With Woolino, there is no need to worry. The exceptionally breathable Merino wool naturally regulates baby's body temperature, which helps your child to sleep safely and comfortably through the night. It gives you peace of mind and a good night sleep as well.

This amazing baby sleeping bag also saves you buying different sleep sacs for different seasons - you can use it year-round.

  • Woolino's 4 Season baby sleeping bags are designed to be worn year round. They are made from 100% natural breathable fibers and contain NO synthetic filling.
