Product Reviews

We swear by the Halo SleepSack!

We swear by the Halo SleepSack and have used them for both of our boys from when they were newborns all the way to when they're ready to use blankets in the beds. It gives me great piece-of-mind knowing that my baby is warm and safe in their SleepSack when I put them into their beds.
