- Reviewed in the United States on May 10, 2025Color: BirdsSize: Small (Pack of 1)Verified PurchaseMy newborn is just 2 weeks old, about 8.5 pounds, and absolutely fights having his arms restricted. Most swaddles just made him angry, but this one lets his arms be completely free, which he seems to love. It fits him really well right now, not too snug but also not so loose that I worry.
One thing I've learned is to make sure he's wearing pajamas underneath that have the little hand covers, or even just baby mittens. Since his arms are out, he can definitely still get his hands to his face, and those newborn nails are surprisingly sharp! This sleep sack combined with covered hands has been our best bet for calmer nights so far. If your baby also despises being pinned down, this style is definitely worth a try.
- Reviewed in the United States on May 15, 2025Color: Aster Flowers-purpleSize: Small (Pack of 1)Verified PurchaseI’ve been using this since my baby was around two months old and I am just so happy with it. I was hesitant about it at first because it seemed way too big, but as time has gone in, I’ve realized that it’s not too big, it’s exactly what’s needed for baby to have plenty of room to kick and spread their legs out. Loved it so much I ordered the next size up and I’ll continue purchasing this for every new size baby needs. It’s not super thick which is great for us. It’s like a think blanket wrapped round baby so she can still have her normal pajamas with a little extra warmth.
- Reviewed in the United States on May 28, 2025Color: Pink ToileSize: Medium (Pack of 1)Verified PurchaseMy six month old LOVES this. I ordered it for the summer months for my in-laws house for her naps (I swear their house is warm) and it’s the perfect TOG for the warmer days. I had to order one for my house as well as we get into summer. My daughter sleeps great in this.
- Reviewed in the United States on May 24, 2025Color: Watercolor DinosSize: X-Large (Pack of 1)Verified PurchaseLove this sleep sack! My son sleeps so well with it! We weren’t able to get our son sleeping in his crib until he was a year old, but as soon as we tried this sleep sack he instantly loved his cribs and goes down so easily for naps and bedtime as soon as he puts it on. Would definitely recommend it!
- Reviewed in the United States on May 17, 2025Color: Aster Flowers-purpleSize: Large (Pack of 1)Verified PurchaseMy favorite sleep sacks for my daughter! Halo is the only brand I will buy now. They’ve just worked for us and my daughter seems to love them. Great material and cute patterns! She seems comfortable. This purple one is great because it has a double zipper which is so helpful when I’m trying to zipper her up in the dark.
- Reviewed in the United States on May 29, 2025Color: Animal PaintSize: X-Large (Pack of 1)Verified PurchaseLove these and recommend to all my expecting friends. So easy to use and wash and hold up so well. Using the same ones for my second baby now. Great fit and last forever.
- Reviewed in the United States on May 16, 2025Color: Twinkle PinkSize: Medium (Pack of 1)Verified PurchaseNot sure why their other sacks have a two-way zipper but this doesn’t. Otherwise a great product!
- Reviewed in the United States on May 19, 2025Color: Soft PinkSize: Small (Pack of 1)Verified PurchaseObsessed with this sleep sack, I love the fabric, it’s light weight, soft and perfect for summer nights. Love the color wave, texture, and zipper quality. It’s the perfect size and length and very durable. I’ve washed this more times than I can count and the quality has remained the same. 10/10 would recommend!

4.0 out of 5 stars Thin, but does the job
Love Halo sleep sacks, this one though us very thin and not the same material as the previous dudes that I’ve ordered for my kiddos.
- Curtis T.Reviewed in Canada on July 12, 2021
2.0 out of 5 stars Normally Halo sleep sacks are great but this one isn’t.
Halo sleep sacks are normally great but this one the quality is bad. After minimal use the fabric and threads are starting to fray and as such is now unusable as they pose a safety risk. Such a disappointment.
