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.

- HannahVerified Reviewer3/11/25ReviewingSleep Suit Bag 3.5 TOG WillowRated 5 out of 5 starsLove this sleep suit bag!
I was gifted this suit to borrow and we are so in love with this. The fabric quality is supreme, the Willow print is aesthetically pleasing, the design is genius. Baby is currently 5 months in a cold climate and it has been wonderful, eager to pass it alomg to other friends next winter who need a small amd super warm sleep sac. Looking forward to buying a bigger size lighter fabric for summer soon!
