Buying advice

When choosing an adjustable sleep sack, consider your baby's age, preferred sleep position, room temperature, and ease of diaper changes. Look for adjustable length/accommodating to growing babies, TOG rating for season, and material (cotton vs bamboo). Always ensure the sack is snug around the chest without bunching up.
