The Sleep Suit Bag is an award-winning, multi-functional Sleep Bag and Sleep Suit with legs in one, for babies, toddlers and kids.
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.

Great lightweight sleepsack but already has a hole in it. So disappointed as we love Ergopouch products.

I'm disappointed that there are zippers at the back. This age range is more curious and developing motor skills to unzip so I would've preferred that this was kept clean and minimal.
