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.

Great for baby's sleep
Would buy a million of these if I could. The material is perfect. The pattern is beautiful. It's a soft and breathable fabric.Best part - the zipper. I don't have to try and latch the zipper because it zips up, not down.Our little one sleeps well in this and it keeps her warm without overheating during naps and night.Has plenty of room for the size/age range to grow in. Her feet are getting closer to the bottom but still has room to move without issues.

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.

Essential baby gear
I consider these to be essential baby gear!! I love that they keep my daughter warm & comfortable, while also keeping her safe. The double zipper system is a life saver for middle of the night diaper changes as well. It's not at all heavy, the fabric is soft yet durable, and it holds up perfectly when ran through the washer & dryer!

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.
