Size Guide
Sleep Suit Sack
Please use your child's weight to find the most appropriate and safe size for them. The Sleep Suit Sack 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 Sacks should not be used in a 5-point harness or car seat for safety reasons.

Beautiful design and great material, perfect for this weather.
- Sarah F.Verified Buyer2/24/25ReviewingJersey Sleep Suit Sack 0.2 TOG WillowRated 1 out of 5 starsDisappointed
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.
- Chelsey W.Verified Buyer1/13/25ReviewingJersey Sleep Suit Bag 0.2 TOG PebbleRated 5 out of 5 starsLovely sleep suit
This is such a lovely sleep suit for my toddler. He has plenty of room to move and grow into. The fabric is soft and breathable, perfect for these warmer QLD evenings. I love the grippy patches at the back for when the legs are zipped apart. Very happy with this purchase.
