The HALO® SleepSack® wearable blanket Quilted Muslin Platinum Series replaces loose blankets in the crib that can cover your baby’s face and interfere with breathing. In addition to helping your baby sleep safer, the HALO SleepSack wearable blanket helps your baby sleep better, too. This HALO SleepSack wearable blanket is quilted with soft, breathable, cotton muslin and a cotton jersey lining for softness. It is a warm cuddly blanket your baby cannot kick off, ensuring baby sleeps soundly throughout the night. A two-way zipper with tab covers at top and bottom allows for easy diaper changes and makes dressing easy. The HALO SleepSack is recognized as "Hip Healthy" by the International Hip Dysplasia Institute.
