lots of use out of these sleep sacks.
My daughter has been using this sleep sack since 6 months old, sheâs almost a year. We purchased 2 of them and she alternates between the two. She usually wears them 2-3 times before I wash so they have been washed many many times and have held up well! she seems comfortable in them at night as well. Not too warm which I was a concern considering theyâre fleece.Good buy! Will be purchasing in a larger sizes soon 🙂
This has the double zipper!
Thankfully this sleep sack does have the double zipper so you don’t have to fumble with lining up the zipper to do it up like most of them. You simply move the 2nd zipper from bottom to top. For whatever reason the packaging I have seen never indicates if it has that double zipper so its always a guessing game. This sleepsack is cozy and still has room for my wee one to grow. She wears 2T clothes. No complaints.
Best Sleep Sack Out There
I will NEVER buy a different brand of sleep sack. We are using the same one from my son from 3.5 yrs ago and itâs still perfect. I like that the material is warm yet light enough the baby can move around easily.I ordered another one for my daughter to nap at day home in.
Nice and soft
Was great for my granddaughter. Light and warm.
Perfect for my 2 year old!
The Xlarge is the perfect size for my 2 year old and the fleece is great for cold Canadian winter nights!
Love it!
This is a must have. My newborn went from being swaddled every night to wearing this, itâs nice and warm and itâs her well.
Comfy and cozy!
Bought this for a friend who has a newborn that doesnât like to be swaddled. She loves it!
Great Sleep Sack
This sleep sack is a great buy. It takes the worrying out of knowing if the baby is cold or not.
My daughter sleeps very well in these, I keep buying them in a larger size as she grows. They wash well, the zipper is quality, and they keep her warm in the night.
For some bizarre reason this sleep sack while clearly marked LARGE. Is the exact same length of the MEDIUM I was replacing!!!!!It is substantially wider? But I am so frustrated that the length isn’t the additional 5″ that it was supposed to have been.Too late to return it as I have already washed and removed the uncomfortable tag that is at the back of the neck.
We’ve bought other Halo Sleepsacks from Target without any issue. But we only used this one a handful of time and the zipper broke in multiple spots.
This is not only lightweight, but washes up nicely without looking worn
Love our halo sleep sacks! Wouldnât use any other!
