SAFE AND SECURE SLEEP SOLUTION: The Original Halo Sleepsack Swaddle replaces loose blankets in the crib, creating a safer sleep environment. Endorsed by hospitals nationwide to promote safe and restful sleep for your baby.
SOFT AND STRETCHY COTTON: Made from 100% cotton with a double-knit construction, offering a cozy and slightly stretchy feel perfect for swaddling. TOG Rating 1.5 (room temperature of 68°-72°F): Suitable for cooler evenings during spring or fall.
3-WAY ADJUSTABLE SWADDLE DESIGN: Generously sized fasteners allow a perfect, customizable fit. Adjust the swaddle for Arms-In to reduce startle reflex, One-Arm-Out hand to face for self-soothing, or Two-Arms-Out to transition to the Halo SleepSack, an easy transition when it’s time to stop swaddling.
CONVENIENT DIAPER DESIGN An inverted zipper opens from the bottom, allowing easy diaper changes without disturbing your baby’s swaddle. Sleeveless design minimizes overheating risk, while snug arm and neck openings ensure a secure fit.
SIZE NEWBORN – IDEAL FOR NEWBORNS (6-12 lbs): Specially sized for babies 0-3 months old, weighing 6-12 pounds, and measuring 19-23 inches. Discontinue use when baby begins rolling over or attempting to escape from the swaddle.

Soft, and Breathable
This is a great swaddle. Easy to use and no complicated folds. 100% cotton so it is breathable and not too hot but keeps baby warm and secure feeling. I think every grandparent or parent who wants to be able swaddle quickly and securely should purchase one.

1 week old grandson loves it!!!
The HALO 100% Cotton Sleepsack Swaddle has been a lifesaver for our family. It’s truly the only swaddle my 1-week-old grandson loves. He settles quickly, sleeps more soundly, and seems so comfortable in it. The fabric is soft and breathable, and it’s easy to use—highly recommend for newborns!

Amazing sleep sack.
This sleep sack is great. It’s made well and it keeps the baby warm without worrying about using a blanket in the crib to keep them warm. I have multiple and buy them for shower gifts. I highly recommend this product.

Great for a little bit
It’s great to help get our baby down to sleep. Past 2 months though she began punching out of it. There’s also a space by the flaps she would get her arms through almost every night and occasionally it would make it so she would cover her whole face.

Great quality
Honestly love the versatile of the swaddle my baby loves it so much and he is two months old. I can either put his arms in or out, and it makes him feel like he has a blanket on them great product.

Easy to use
This worked great until my baby didn’t like being swaddled any more and needed to transition to a different TOG.

Good Quality, But Not a Hit With My Little Escape Artist
I really wanted to love this Sleepsack Swaddle. The cotton fabric felt nice and soft, and I appreciated the TOG 1.5 rating, as I’m always trying to make sure my baby is at a comfortable temperature. The baby blue color is sweet too. The idea of the 3-way adjustable design seemed versatile, which was a big draw.Unfortunately, it just wasn’t the right fit for us, or rather, for my baby. My baby absolutely fights being restricted and would get so frustrated in this. If your baby is similar and doesn’t like their arms pinned, this might not be the one for you. Also, I found it a real struggle to get a good, secure swaddle after a feed when my baby was all curled up and sleepy. Trying to arrange the wings and Velcro with a tiny, curled-up newborn was more challenging than I anticipated.Pros:The cotton material is soft and breathable.I liked that it’s a wearable blanket, which feels safer than loose blankets in the crib.The 3-way adjustability is a nice concept for different sleep preferences, assuming your baby tolerates swaddling.Cons:My baby strongly disliked having arms restricted and would fuss a lot.It was difficult to get a snug swaddle when my baby was curled up after feeding.Didn’t end up working for us due to baby’s preference.Overall, it’s a well-made product, but it really depends on your baby’s temperament. For us, it was a bit of a miss, so I’m giving it three stars.

The band was too big compared to other Halo 3-6 month swaddles. Could barely get it to Velcro because it was so big. Soft, stretchy, and great quality.

Excellent quality no flaws. Item exactly as described

Tenía mucha expectativas con ese producto . Compré 2 y no los usé. El sistema del velcro hace ruido y el sistema de cremallera es pesado , para unos recién nacidos muy pequeños. Hubiese preferido un saco de dormir normal .

Nice product although costly.
