Love the quilt-like design and quality!
This sleep sack is great for a chilly room. Our little one’s room seems to stay about 5 degrees colder than the rest of the house so we were looking for a warmer sleep sack for the winter months. She has been warm and cozy, no matter what the temp is in her room. It’s a nice quality product that is soft, thick, and quilt like (it has a nice weight to it). It did shrink about an inch with the initial wash, which I was a bit bummed about because it just means she will grow out of it that much sooner, so I would order a little bigger than you think.

Cute colors, great product
I bought a few of these in different colors. The value for your money is great and zipper functionality is perfect. I like that. It has a fabric tab to cover the top of the zipper to avoid rubbing on my babys chin. The colors were as pictures and the fabric weight it light enough to keep warmth in without sweating your baby out. The fit is as expected and the fabric does stretch when they kick but not too much which is nice.

Warm and comfy
Nice thickness from the double layer of fabric that feels nice. Two way zipper is super nice. We’ve had it about three months and so far there are no signs of wear from the washer/ dryer.

Perfect sleep sacks for toddlers — breathable, safe, and soft!
I’m so glad I found these Yoofoss sleep sacks! I’ve tried several brands, and this 2-pack is hands down the best value for the quality. The fabric is super soft and breathable—perfect for our 72°F nursery. The 1.0 TOG weight keeps my toddler cozy without overheating, and we’ve had no sweaty wake-ups since switching. The two-way zipper is a lifesaver for nighttime diaper changes (no more full undressing!), and the zipper guard at the top is a thoughtful touch to protect their chin. After multiple washes, the sacks still look and feel great—minimal shrinkage, seams holding strong, and no fading. Sizing is true to size, though if your little one is on the taller side, you might outgrow the smaller size range sooner. I love the roomy fit for kicking legs and healthy hip development. And the designs are super cute and gender-neutral, which is great for hand-me-downs. Highly recommend if you're looking for a safe, comfortable, and well-made sleep sack. It’s really helped our toddler sleep longer through the night—and made my life easier, too!

Amazing and baby loves it
I order this sleep sack looking for dupes of the Halo Sleep Sack. The materiel is soft and lightweight while also providing great warmth, at night the house is cold and baby’s temp is maintained well. I’ve washed the sleep sacks multiple times and there is no shrinkage and still maintains its stretchiness and color. It works very well and I have no issues with the zippers. The size is as the chart follows although if your baby is on the bigger/longer side you may want to size up for more leg room. Only small complaint I have of the cover for the top zipper is a hit or miss and will not always cover the zipper all the way.

We use these every night!
We’ve used these every night for the past few months and they have held up great! They are comfortable for our twins and have fit them for the last few months without having to buy the next size up. They’re soft and well made and perfect for the temperature we keep our house at (about 70 degrees). We will definitely be buying the next size up soon!

Perfect winter sack
So warm and cozy! Our little one loves it when we crank the heat down at night in the winter. It is thicker than any tog 2 I’ve used on the past.

Nice sleep sack
It’s perfect in winter for the home does not turn on the heater. The fabric material is soft. The color is mutual. The style is simple and it’s easy enough for changing diapers. A perfect choice for gift.

Buena calidad en las telas. Cumple la función de mantener al bebé abrigado sin tener que utilizar cobijas. Ya compré el delgado, medio y muy grueso y todos cumplen la función Lo recomiendo ampliamente
