What weabout it
Hip-healthy swaddle sack in mid-weight cotton adjusts to accommodate multiple sleep styles, with optional access to hands for self-soothing.


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 their 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 them transition smoothly out of full swaddling.

The HALO swaddle is 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's the perfect design for a sleep sack with easy zipper and body coverage to keep baby warm and allow mobility without excessive fabric. Also very soft.

Love the different arm positions that are possible - from arms in to out. And it’s so easy to use.

At first we felt our baby was too small for these but after a week or so we tried it again and never looked back! She was so comfortable and it's so much easier to swaddle in these than a normal blanket. We definitely recommend the cotton over muslin, though, because when she got a little older and started moving more, the muslin would bunch up at her neck when she moved her arms. The cotton stayed on the velcro much better and we used these up until she was sufficiently rolling and grew out of them. We've graduated to the Halo sleep sack without swaddle now! Sleep Sacks are the best! We barely even used the swaddle blankets we got because these things are a dream and so easy to use. They were a great comfort for baby, too, and she knew when she was wrapped up it was time to sleep. Definitely get cotton over muslin, though!

After the first few weeks, this was the best sleep aid for baby. He loved this much better than the traditional swaddle blankets.

Perfect for those first couple of months. Baby was nice and comfy. Easy to use for mom - and a brand name I could trust.

They're warm and cuddly and easy to put on and off, adjustable, etc.

Perfect for our little escape artist who could not be swaddled in a blanket. She slept great in these, and then we used the wrap under her arms at about two months when she didn’t need the swaddle anymore.

Make sure you Velcro it together before throwing in the wash so it doesn’t stick to everything else.
