HALO 100% Cotton Sleepsack Swaddle, 3-Way Adjustable Wearable Blanket, TOG 1.5, Cream, Newborn 0-3M
HALO 3-way adjustable 100% cotton SleepSack swaddle in cream, TOG 1.5, sized for newborns 0-3M.
A sleep sack is a wearable blanket that keeps your baby warm without loose bedding in the crib, making it a safer choice than a blanket. Look for a TOG rating matched to your room temperature, a roomy bottom that lets hips and legs move freely, and a well-fitted neck and armholes so the sack cannot slip over your baby's face. Two-way or bottom-up zippers make dark-room diaper changes far easier. Sleep sacks suit babies who have outgrown swaddling and any family wanting to follow safe-sleep guidance of a bare crib. Sleeveless designs work across seasons with the right layer underneath. A practical tip is to check the room temperature and dress your baby in one light layer under the appropriate TOG, avoid overheating, and size down rather than up, since a sack that is too big can shift and bunch during the night.
