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.

- Natasha B.Verified Buyer7/14/25ReviewingSleep Suit Bag 3.5 TOG WillowRated 5 out of 5 starsSoft
Been a fan of the brand since my son was born. Brought new and 2nd hand ones. The legs options is perfect so he can move around a little safer, without tripping but we all know sleep sacks kids work out how to walk in them anyway. It's soft, keeps him warm. Easy to convert. Love the brand.
- Victoria H.Verified Buyer7/1/25ReviewingSleep Suit Bag 2.5 TOG BerriesRated 1 out of 5 starsNot recommend
Top of the zip has left a sore at the base of my 3 month old baby's neck due to bulky stitching, poor design and inferior craftsmanship. Would not recommend this item.
