Great quality
Love the soft and comfortable material! Itâs light weight and keeping my baby warm!! The color has not faded in wash and material did not shrink in the wash! I have washed them few times now and still look great!
Great purchase!
I’ve always purchased Halo brand sleep sacks but decided to give these a try. Absolutely perfect. Not too thin. Holding up well with multiple washes. Keeps my baby comfortable at night. Would recommend as a pack of 3 for this price is a steal!
Really nice material
Completely recommend. My baby can’t sleep without these sleep sacks in particular. They’re good quality, nice and warm and I’m assuming comfortable based on how she sleeps since purchasing them!
Lightweight , soft and cozy.
These are perfect for my little guy. They fit nicely, not too tight, but not too loose. He is comfy and has just a little extra warmth with these and no issues with it being loose around his neck/ face like some other brands. This is my favorite of all the sleepsacks we have tried!
Good sleep sacks
They are lightweight sleep sacks. Made from a durable materials but they will shrink in the wash. I suggest sizing up! The zipper goes up, so if you do not like that then this isnât the right one for your little one. However itâs very comfortable and convenient and the price is reasonable!
Lightweight soft
Very good quality nice and soft for baby definitely recommend! They are quite long but hasnât been an issue for us!
Great purchase!
Love these, and affordable. Good size too.
Very Nice Sleep Sacks
These are great sleep sacks. They’re a nice weight for when it’s warm out, they’re soft and they wash well.
I bought these sleep sacks for my now 9 month old son. I waited until I had them for a month to write a review. I have had zero issues with them. The zippers are great, they hold up in the washer and dryer, and the colors stay vibrant! The only problem there has been was they did shrink 1 1/2 to 2 inches after being washed and dried. See pictures. This wasn’t a problem for me because I have a little guy. For reference he is 9 months old, just now getting into 6/9 month clothing, he is 18.4 pounds and 21 1/2 inches long. I bought the 6/12 month sacks. They are pretty big on him but not to where they are a safety hazard. He absolutely loves them and uses them every night! They are a bit on the thinner side which I prefer. We live in Texas and it is super hot right now. He sleeps in these and a onesie with the AC on, and he is very comfortable. I highly recommend these sleep sacks for the quality and price!
I am very pleased with the Unnivoll Baby Sleep Sack 3 pack! The sleep sacks are true to size, incredibly soft, and so comfortable for my little one. The cute designs are just a cherry on top. My 9-month-old sleeps like a rock, and I truly believe these sleep sacks have contributed to that. Plus, the double zipper makes night time diaper changes a breeze. Highly recommend these for any parent looking for quality and convenience in their babyâs sleepwear! By baby is outgrowing his and we are definitely buying the next size for him to be able to continue to wear these to bed!
Newborn hates swaddling and would scream if her arms were constricted. These are perfect and comfortable for layering ontop of footed pajamas, easy to use/clean, colors are cute, and keeps baby warm enough through the night to get some good sleep! They should fit her for a little while too as she grows, so good bang for your buck!
These sleep sacks are great! They’re comfortable, wash well, and are easy to get on the baby. I love that there’s a double zipper, which makes middle of the night diaper changes easy. Baby stays at a comfortable temperature wearing a sleep sack and a long sleeve/footed pajama, and the sleep sack moves with her easily when she moves and rolls around during her sleep (which is a lot!)
They have been through the washing cycles multiple times and have still remained the same size, as well as kept their softness. They are super lightweight and nice material.
