Best Space Sleep Sacks in 2026

SIZING: Please measure your little one from head to toe and match the length of your baby with the corresponding size next to it on our sizing chart. Please do NOT buy one size up! The bag will not fit until your little one reaches at least 2 to 3 months for the small size, 30” for the medium size and 37” for the large size. It is generally recommended to swaddle your infant for the first 2 to 3 months or when they start to roll. Choose a sleeping bag that’s suitable for the season.
