Obsessed!
Obsessed 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!

The BEST sleep sacks out!
We’ve used Halo swaddles and sleep sacks with all 3 of our kids and they are the BEST. None of them can/could sleep without it. My 2 year old wore them until he was a year and a half! This one is for my 4 month old and I love that it’s muslin. It’s so lightweight and perfect for summer with little babies who need it to sleep but gives us the piece of mind that she won’t overheat! Another plus is that it’s wide enough that it won’t hurt their hips. Hip dysplasia runs in the family so that was a concern of mine. We did have one zipper break, but it’s still usable and the one that broke was passed down through all of our kids so it makes sense.

Comfortable and soft
As a parent, I have found the HALO SleepSack to be an absolute game-changer in ensuring my baby's safety and comfort during sleep. This product eliminates the need for blankets, which not only reduces the risk of suffocation but also provides peace of mind knowing my little one is snug and secure throughout the night. The SleepSack itself is incredibly soft and well-made, offering a cozy environment that my baby loves. The zipper design makes it easy to put on and take off, even during those late-night diaper changes. I appreciate how it promotes healthy sleep habits by keeping my baby warm without overheating, thanks to its breathable fabric. Another standout feature for me is its versatility. Whether we're at home or traveling, the HALO SleepSack ensures consistent sleep conditions for my baby, which is crucial for maintaining a routine. Plus, the variety of sizes and designs available allows me to choose one that suits my baby's needs and our style preferences. Overall, the HALO SleepSack has exceeded my expectations in terms of quality, safety, and convenience. It's not just a sleep essential; it's a peace-of-mind essential for any parent who prioritizes their baby's well-being.

Buy!
Huge fan of the halo sleep sacks. I actually feel comfortable putting my son in them. I love that they’re not weighted and are super cute and warm. Though we’ve had many, we have never had any sort of problem with the zipper, ripping or it not being stretchy enough.

Baby ended up liking it!
Update: now that the weather is colder and baby is wearing fleece footies underneath he is nice and comfortable and is enjoying this sleep sack now. Win! 👏🏻 I don’t recommend this sleep sack for summer- even though it is only 1.0 it is thick and warm.

Great lightweight sleepsack!
We love this sleepsack. It's been almost a nightly wear since we got it 3 months ago, and it has traveled with us through seasons and climates and has been very versatile the whole time. Also, the llama print is super cute! We got the large when the baby turned 10 months. It was big, but not unsafely so, and it still fits here with plenty of room at 13 months. Our baby is a little chunky with a big noggin though, so there's no fear of it coming off her arms or over her head. When we got this, we lived in a mountain town that had cold nights. We made it work as a heavier sleepsack by putting her in a warm fuzzy onesie inside the sack. Now, we live in a hot climate, she just wears a diaper inside the sack. We keep our house pretty warm, and she doesn't get overheated inside it. She started walking not long ago, and while she can stand inside the sack, it's not great for her to walk in it as it's a trip hazard. She can scoot around on her hands and knees pretty well though. The few times she's had it one before bed, we just undo the zipper at the bottom so she can have her feet free and she wears the top like a cape (under supervision, since it's still a trip hazard.) That zipper also makes diaper changes super easy. We think the quality is great and its stood up to near nightly wear for 3 months no problem. However, after seeing some reviews regarding zipper, I feel it necessary to say we haven't had any zipper issues - our zipper is metal and has held up well. It also has repelled stains pretty well with the usage of shout, and we haven't experienced fading issues. Overall, we love this sleepsack and would buy one again in a heartbeat.

The best out there
We tried others and these are probably the best in comfort and quality. I don’t know why kind of magic it holds because as soon as I swaddle baby is asleep. Stretchy and soft and looks like new even after multiple washes.

Excelente para el verano, ya que la tela es ligera. Muy grande para usarlo en recién nacido y los primeros dos meses

Excelente producto, súper fresco para usar en primavera-verano y aún mantiene el calor de mi bebé, es tela muy suave y me encanta que no tengo que descubrir a mi bebé para cambiarle el pañal en las noches. Me da la tranquilidad de que se mantiene a perfecta temperatura al dormir sin tener cobijas sueltas que representan un riesgo.
