Size Guide

SIZE GUIDE

Standard and Long Sleeve sleeping bags

Our sleeping bag sizing is generous because your child should be able to kick and wriggle freely in the sleeping bag. Ideally babies' feet should be at 3/4 of the sleeping bag, leaving the bottom quarter of the sleeping bag 'empty'.

Therefore, it is advised you buy the sleeping bag based on your child’s age and do not go a size bigger. It is not safe to use sleeping bags that are too big. Your child’s head should not be able to pass through the neck hole when the sleeping bag is zipped up, otherwise it is too big. These sizes are recommendations only. Every child is different, so always try the sleeping bag on for size and refer to our sizing guide carefully before purchasing.

Size Example: Child’s height 28 inches = (M) 6-18 months

*SIZE L : 18-36 MONTHS (adjustable) : This size has velcro patches on the back to ‘grow’ with the child: 18 months to 2 years (folded), up to 3 years (extended).

Measurement ‘E’ applies only to bags with sleeves. Slumbersac sleeping bags are available in 6 sizes.
