The Sleep Suit Bag is an award-winning, multi-functional Sleeping Bag and Sleep Suit with legs in one, for babies, toddlers and kids.
Size Guide
Sleep Suit Bag
Please use your child's weight and height to find the most appropriate and safe size for them. The Sleep Suit Bag should be fitted around the neck and the armholes to avoid your child slipping through. In 'legs' mode, there should be enough length at the end of the suit to allow your child to move their feet freely. 2.5 TOG and 3.5 TOG Sleep Suit Bags should not be used in a 5-point harness or car seat for safety reasons.

This baby sack is perfect. My 22-month-old does not like to feel trapped/wrapped, and we bought a size 2-4 years old, and it is perfect. He sleeps all through the night and keeps him warm.
