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.

- Cate G.Verified Buyer5/23/25ReviewingSleep Suit Sack 3.5 TOG WillowRated 5 out of 5 starsGreat!
My daughter is 4.5 and doesn't sleep under blankets so this is perfect. I've been using these sleep bags since both my kids were babies and they always give me peace of mind that my kids will sleep so soundly. The quality is excellent and I love that they can be put in the dryer!
