About this Product
  • Easier, foolproof way to swaddle
  • 3-way adjustable swaddle
  • Inverted zipper opens and closes from bottom


The HALO SleepSack Swaddle has all the benefits of a traditional swaddle, but in a much simpler and foolproof design. The Velcro wings make it easy to wrap the swaddle around your baby and keep his or her arms safely immobilized, preventing the startle reflex that can disturb rest. As a bonus, the 2-in-1 adjustable design of the SleepSack Swaddle actually lets you to keep your baby’s arms inside or outside of the swaddle. This maximizes your child’s comfort and eventually helps him or her transition smoothly out of full swaddling.

The HALO swaddle is embroidered with “back is best” on the front, reminding caregivers to always place your baby to sleep on her back. It’s meant to be used over PJs in the place of a loose blanket.

The zipper opens and closes from the bottom, making diaper changes easier. And the roomy sack at the bottom allows your baby to move her legs freely, promoting long-term hip health (though some babies sleep better when both legs and arms are wrapped snugly).

Parents report that the HALO SleepSack Swaddle holds up well to washing, but do remember to attach the Velcro to itself so it doesn’t stick to itself or other items in the wash. Stop swaddling when your baby shows signs of rolling over or breaking out of the wrap.

To use the HALO SleepSack Swaddle, first zip your child into the main pouch. Then wrap the Velcro wings around each other, keeping your child’s arms under each wing as you go. See HALO’s video below for more details.

It makes swaddling and midnight diaper changes so easy! It’s also versatile; my son has always slept arms out and this allowed him to do just that, but your baby could just as easily have it’s arms tucked in.

It’s like a blanket but stays close to baby body. once baby gets to be 4-5 months and doesn’t need swaddling it’s still comforting but give them ability to move arms and legs.

We tried to use the HALO sac a few times, our baby wasn't a huge fan of it.

Our baby wouldn't sleep without this the first 4-5 months. It is super easy to use, magical sleep aide.

Easy to put on, both my children seemed to love it.

We used it after transitioning from the Merlin’s magic suit. It’s perfect to use for a “blanket” for the baby but safe!

I loved this until my baby started busting out of it. Unfortunately, I could only use it for a short time, but I felt it got the job done and helped my son sleep.

Safe, easy to use, can easily transition to one arm out.
