Our Sleep Sack is a baby and toddler sleeping bag designed for arms-out sleepers (usually from around 3 months of age). The Sleep Sack has a slim-fit, stretchy design similar to that of a swaddle and is recommended as baby's 'first sleep sack' after the swaddling phase is over. Please use your child's weight and height to find the most appropriate and safe size for them. A sleep sack should be well fitted around the neck and the armholes to avoid your baby slipping through. It should also be bell shaped in the bottom to allow for easy leg movement. Please do not size up to the next size until your child meets the weight requirement, for safety reasons.

All sleeping bags we have from ergoPouch are amazing. The fabric is so soft and washes well. We have them in all the different tog ratings and it’s so nice knowing our daughter is at the right temperature over night. Highly recommend ergoPouch!
