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.

My little one loves this sleep sack. It has been perfect for the warm, humid weather. It’s stretchy and made from really good quality cotton. It’s breathable and feels nice on the skin. Highly recommend.

We LOVE our sleep sack!! It fits our baby so comfortably and it’s warm without being overly toasty. They also wash really easily and can just get thrown in the dryer, which we love. We’ll keep using these sleep sacks as long as possible!
- Krystal V.Verified Buyer9/12/26ReviewingSleep Sack 1.0 TOG WillowRated 5 out of 5 starsLOVE
I love these sleepsacks. They're just snug enough that they feel secure, just thick enough that they keep my baby not-too-wam throughout the night, and are just so cute. We love them!
