Sizing Information

Size Age Weight Sleep sack length
Small 0-9 months from 10 lbs (4.5kg) 30 inches (76cm)
Medium 6-24 months from 18 lbs (8kg) 36 inches (90cm)
Large 18-36 months + from 24 lbs (11kg) 42 inches (105cm)

We recommend that you wait until baby is over 10lbs. in weight before using the sleep sack. (Generally speaking around 6-10 weeks)

Please note: There is a certain amount of overlap in the sizing. The goal of a good fit in a sleep sack lies more in the chest and less in the length. The fitted neck and armholes ensure that there is no danger of either slipping in or out of the sack, provided the baby is placed in the correct size for his age/weight. All of our sleep sacks are long in length and should have plenty of room for the baby to "grow into".
