Size Guide
Sleep Suit Bag
Please use your child's weight 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.

It was worth it to wait little bit longer because of worldwide shipment. I love as the quality as the design. The top is a thermometer with concrete chart, which helps me to chose a correct sleeping bag.
Love it!!!
