The Snug-a-Bug is the perfect little outerwear for preemie babies. The soft warm polar fleece fabric will help keep your little one cozy this winter. Just slip their little feet in, wrap them up and the built-in hood will keep little heads warm. For a snug fit, there is extra long velcro on one of the sides that allows for adjustments. The other side is long enough to be tucked around the baby for a nice snuggle.
