What weabout it
Adjustable microfleece swaddle sack keeps babies snug and warm in colder temperatures


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.

It also has versatility to match your baby’s sleep style and stage of development. It has a bag-style zippered sleep sack with an attached, adjustable upper body swaddle that wraps around your baby’s arms and torso. You can wrap your baby with her arms snugly at her sides, hands-to-face, or with one or both arms free. Some babies sleep better in the more cocooned wrap, and others need access to their hands for self-soothing. Large, adjustable Velcro fasteners on the top part of the swaddle help you get just the right fit.

The soft, polyester micro-fleece of this version of HALO’s swaddle sack is super warm (rated 3.0 TOG for temperatures between). It works well in cold environments, but you will want to select a lighter weight swaddle for more temperate climates or if you keep your home heated at night to prevent overheating.

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.

I wish I knew it was okay to bring home the one from the hospital - our baby slept in this the first 3 months. At 6lb the newborn size was necessary - she was swimming in the size small we had at home and had to go buy this one the first night home!

Cozy for the wintertime.

It’s great quality, my baby didn’t like being tightly swaddled so we cut the wings off and just used it as a sleep sack. We now just buy the sacks without the swaddle function. Fighting the Velcro in the laundry and during diaper changes was too much for a baby who really didn’t want to be swaddled anyway.

Easier to use than swaddle origami or baby burrito, especially during the first couple of months with baby at home. The velcro "wings" have what we described as industrial strength velcro, but our little one would sometimes manage to wiggle his arms out. We had to find a way to maneuver our little ones arms and tuck the excess fabric around so it was safer (nothing loose to suffocate on for baby). Unsticking the velcro can be LOUD (enough to wake a newborn) and the velcro sticks to various fabrics, particularly new parent lounge clothes!
