TOG (Thermal Overall Grade) is the warmth rating used for baby sleepwear. It measures how well a fabric traps warm air to keep your baby at a comfortable temperature. The higher the TOG, the warmer the sleepwear, making it easier to choose the right SleepSack based on your room temperature.

How to use a 3-way swaddles?
Every baby has different sleep preferences. The adjustable HALO® SleepSack swaddle provides 3 easy ways to swaddle to ensure your baby’s best sleep and to help make the transition from swaddling easier.
What should my baby wear underneath?
It is essential to dress your baby appropriately underneath the sleepsack or swaddle, depending on the room temperature. Use lightweight, breathable clothing, such as a onesie or a light cotton sleeper, in warm weather. In colder temperatures, opt for a warmer sleeper or footed pajamas.
What is a startle reflex?
Swaddling creates a familiar and comforting environment for newborns, reminiscent of the cozy confines of the womb. The snugness of the swaddle provides a sense of security, helping babies feel calm and reassured. Also, newborns have a strong startle reflex that can wake them up abruptly during sleep. Swaddling can effectively limit the jerky movements caused by this reflex, promoting more peaceful sleep and longer rest periods.

"This sack is a useless waste of money. If I want to make it tight enough to actually swaddle, the rough side of velcro completely misses the soft side and attaches to fabric which causes it to pull. I compared to older sacks that I got second-hand and the wings of the new sack are so much longer that the velcro starts at the end of the wing of the old sack. My baby is 11. 5 lbs so near the upper limit of weight and it is still like this. Find a different sack."
— Sarah (1/5)
"Love it! Works very well for our newborn, and I like not having to fully swaddle and unswaddle multiple times a night. We can just undo the Velcro, and unzip if we need a diaper change. The Velcro is very loud and kind of bulky though."
— Maren L. (4/5)
"I have several of these and on this one, the most recent one I purchased, the openings on the bottom of each swaddle wing are so large that my 3 month old can easily work the swaddle loose or push up with his arm through the hole to shift the wrap. This wakes him up and it’s also not safe if it gets close to his face."
— Jennifer (2/5)
"Such a cute design, and helps my baby sleep more soundly! I love all of the different ways it can be used!"
— Emmy S. (5/5)
"This is our second swaddle sleep sack and the dimensions on this one are completely off. The part with the Velcro wraps entirely around her body to where the cotton printed fabric is doesn’t actually attach and snags the fabric"
— Julie D. (1/5)
"Love this swaddle for my premie twins! Allows them to keep their hands by their face, but be wrapped up nice and tight."
— Hannah N. (5/5)
"This design is so precious and the swaddle, like always is perfect!"
— Emmy S. (5/5)
"Cute design and does the job, baby sometimes breaks out of it easily though, so I wish it was stronger"
— Ka V. (4/5)
"Bought for a gift and the baby totally loved it!!!"
— Marie D. (5/5)
"We love the swaddles, they’re so easy to use and work well for putting our little one to sleep."
