HALO SleepSack Swaddle Ideal Temp with IntelliThread Technology helps to regulate your baby’s temperature. This innovative material absorbs, stores, and releases heat to help ensure baby is perfectly safe and comfortable. The IntelliThread fibers are embedded within the cozy fabric and won’t wash out or fade.
IDEAL TEMP FABRIC: HALO SleepSack Swaddle Ideal Temp with IntelliThread Technology helps to regulate your baby’s temperature. This innovative material absorbs, stores, and releases heat to help ensure baby is perfectly safe and comfortable. The IntelliThread fibers are embedded within the cozy fabric and won’t wash out or fade.
SIZING RECOMMENDATIONS: Swaddle must be appropriately sized, snug, positioned around baby’s torso and securely fastened. Ideal Temp fabric is designed to be cozy with some stretch for comfort. Because of this, it can run slightly bigger than our other swaddles. Make sure to choose the correct size for your baby’s height and weight. We recommend sizing down if your baby is in between sizes. View the size chart to select the proper size for your child.
COZY 3-IN-1 SWADDLE DESIGN: This newborn sleep sack features HALO’s signature 3-way swaddle design. It adjusts to fit baby’s sleep style: arms in, hands-to-face, one or both arms out. Our signature “Back is Best” embroidery is a gentle reminder to place baby in the recommended sleep position.
BABY FRIENDLY DESIGN: This innovative sleeping swaddle sack is designed with an inverted zipper for easy diaper changes and scratch-free zipper covers. The roomy sack is recognized by the International Hip Dysplasia Institute as promoting healthy hip development.
MACHINE WASHABLE: Turn inside out and close zipper before laundering. Machine wash cold with like colors on gentle cycle. Close zipper and fastener strips before washing. Tumble dry low. Do not bleach, iron or dry clean.

Love this one
A little lighter than the classic swaddle sack which is nice because my girl runs hot. It wraps nicer too, doesnât bunch as much as the classic. Really happy with this one. Would pay the extra $5 for the ideal temp compared to the classic.
Material is not cotton
I always love Halo sleep sack swaddle and it is the only swaddle I use for my newborn at night. I bought this because it claims that it can regulate the temperature so baby is not too hot or too cold. But I have to return it as I found out itâs made of polyester to achieve that. For newborn Iâd like to stick with 100% cotton so be aware of the inaccurate information in the product description.
Title says it all! These are hands down the best swaddles I have tried! I went through so many velcro swaddles once my son could no longer use muslin cloth swaddles, heâs a little Houdini! These were the best ones we found. They are stretchy and the fabric is so soft and breathable which is so important because my son runs hot. Weâve had this brand swaddle for months and itâs still in perfect condition, Iâd say these are pretty durable! You have to wash them according to the tag otherwise the seams will get stuck to the Velcro and cause some tearing at the seams otherwise they are perfect and are so easy to use. I also love all the designs they have, you donât really need cute ones considering theyâre just sleeping in them but itâs still nice to have a variety of designs. I will be purchasing the Halo Sleepsack as we are transitioning out of the Halo Swaddles but Iâm saving this for baby #2!!
The quality of these sleep sacks are amazing! I have washed these multiple times and they still come out perfect. My baby loves them and it keeps him warm enough, but not too warm. This sack in particular is nice and light for the summer and soft and comfortable. My baby is three months old and he has room to grow in this.
Baby can be a wiggle worm sleeping and has used Velcro swaddles many times and never has broken out of it like he did with this one. This one he was able to wiggle his arm up and out from the bottom and was bunched up by his face. Woke up crying to let us know. Poor guy. Donât recommend.
This swaddle sleeper sack is great because you can swaddle your baby, transition them out of the swaddle (ex. Only swaddle one arm in), and use it as a sleeper sack. It zippers and then has velcro around it. Your baby will not get the Velcro open, itâs very strong.
Best swaddle ever. My baby loves this sleep sack. She only likes one arm swaddled in and this sleep sack makes it super easy for us to do this. Weâve tried multiple brands and this is the #1 best. It also keeps baby appropriately warm but not too warm throughout the night. Never had any overheating issues with this. My baby is 11 lbs and the fit of the small is perfect for her. I have washed this product a dozen times and itâs still in great shape. I have purchased several of these.
