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.

Runs big but highly recommend
I got a medium for my 16lbs baby cause that’s what the size chart recommended but they are HUGE! They are very soft, breathable, and not too thick. Great quality! But just run very big. I can’t wait to use them once he gets big enough.

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.

Lifesaver for transitioning from complete swaddle to arms out
These are absolutely adorable. I bought these when my little one was transitioning from being completely swaddled to arms out. The fact that these have hand covers was a lifesaver. With his hands out he would play with his fingers. Keeping his hands covered prevented scratches to his face from his nails and he fell asleep much faster. The blue dinosaur one is my favorite. It’s nice and warm but not too thick or heavy. My only complaint is that the second sleep sack, the hands didn’t always stay covered. Maybe it was made slightly loose. Besides that. Love. He knows it’s time for bed when he gets his sleep sack on.

Warm and cozy
We tried so many before we realized our baby did not want to be swaddled. Once we figured it out I found these since it was starting to get cold. Love the colors and material, wash very well (they get washed a LOT!), appreciate how easy the zipper is, fits my 3 month old perfectly. Great weight for New England winters

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
