Size Guide
Sleep Suit Bag
Please use your child's weight and height 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.

I bought this and a suit but I was not confident if it makes a difference. My toddler daughter had a warm and cosy sleep last night. She doesn’t let blanket on her at night so this product is an absolute win. I found out that she was cold in her other sleeping bags even having thermal leggings on.

This perfect little (big!) sleep suit is a staple for any family. We’ve had ergo sleepsuit bags since birth and this suit doesn’t disappoint. Soft, comfy, very durable (will last you years!) will keep your little tot warm and snug all winter. 10/10 recommend
