Cozy and Adorable Nighttime Essential
The fabric is incredibly soft against baby’s skin, providing a cozy, secure hug that helps my little one settle quickly for sleep. The cute patterns and colors add a sweet touch to bedtime, while the perfect TOG rating keeps things comfortably warm without overheating. Easy zippers make changes hassle-free, and it holds up beautifully after multiple washes.

As Advertised, Cozy, Room to Grow
Product was as advertised. A little bigger than expected but that's not a bad thing.. still fit well enough that they are safe to wear at night and there's room for baby to grow - we will be able to use these for quite awhile. Love the double zipper for easy on and also easy middle of the night diaper changes. Super soft outer layer and warm cottony inner, cozy but not enough to overheat. Will most likely buy a few more and will buy again a size up as baby grows, that is, IF she grows out of them before we can use a regular blanket!

Such a good buy
Honestly I love these sleep sacks. They are probably the best quality sleep sack I’ve tried. They are perfect for the cold winter nights and feel like a soft blanket. They don’t shrink in the wash. Zipper quality is unmatched. The quilted pattern is so cute as well. They aren’t a lightweight stretchy material, they feel like being wrapped in a thick comforter. My little boy sleeps so well in these.

Warm and cozy
This is the second time I have ordered these sleep sacks for my grandson. I ordered large and now extra large. He loves them! They are warm, cozy and soft. I think they are a very good quality. He sleeps like a champ in them.

Love these!
These are so soft and cuddly. They are roomy and comfortable for your baby. They don’t shrink when washed and the zippers work perfectly. Great value for the money.

Definitely Shrinks but very soft
Very soft and comfortable material with a cute design. My baby currently wears 3–6 month clothes and some 6–9 month outfits. They were outgrowing the 3–6 month Halo sleep sack, so I was looking for a more affordable option. The tag states the sleep sack will shrink 1–2 inches after washing, which is accurate. I washed the 6–12 month green sleep sack and compared it to an unwashed 6–12 month patterned one, and the size difference is very noticeable. I did not wash the 0–6 month size, but based on the shrinkage, I expect it would end up about the same size as the Halo sleep sack, which was already too small for my baby. The picture shows the 3-6mo. Halo on the washed 6-12mo Yoofoss Sleep Sack.

Must have for baby
This is the third time I am purchasing for my baby. The quality, ease of putting in, and size are just perfect. Its very functional Not too thick and not too thin either. Very breathable material. We usually keep the house at 72 degrees during the winter and it seems to keep him at the right temperature. Very durable, use one sleep sack for about two nights and wash them regularly throughout the week and haven’t come across any shrinking. The color has faded just a little bit but thats expected to the amount of washes it gets. Will definitely keep buying a size up as he grows. Highly recommend.

Feels like a blanket
Quality sleep sacks for a reasonable price. These fit my baby perfectly. The neck whole is a good size and I don’t need to wear about it slipping over my baby’s head.

Llego el pedido correcto y antes de tiempo, buen material y muy bonitos. Solo son un poquito grandes y pensé que serían más calientitos pero aún así muy funcionales
