Great buy!
I love these sleep sacks so much! For one, they’re super cute, love the bubbley design. They material is really soft and thick, great for cold nights! My son sleeps really well in them! The zipper works really well, and they’re nice and roomy.

Soft, warm, and perfect for better sleep
I bought this sleeping bag for my grandson, and honestly, it was an excellent purchase. The material is super soft and cozy, perfect for cool nights. It feels warm without being too heavy, which I love.It fits my grandson perfectly, with enough room to move around without being too loose. I also like that it's easy to put on and take off, especially for changing his diaper at night.What I like most is that it keeps my grandson comfortable and helps him sleep longer without getting uncovered. That alone makes it worthwhile.In short, it's soft, warm, and practical for everyday use. I definitely recommend it.

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.

Soft and comfy
Started wearing this for my 10 month old and is so soft and comfy! Great for winter and summer if you keep underclothes light. Quality seems good and we love the 2 way zip. We will order again if needed!

So soft and warm!
Our 8 month old was getting cold at night, we bought this and it changed everything! She is so nice and warm, and we feel good that she's still safe sleeping but able to be warm which helps her sleep though the night.

Cozy Sleep Sacks Great for Colder Months
I love these sleep sacks. They're a great texture, keep my daughter warm without overheating, they wash/dry well, and I love the double zipper. Only downside is that I think the sizing is slightly off. While my daughter is tall for her age, at 7 months I don't think she should be outgrowing the 6-12 month size quite yet. She's just sizing up to 9 months in regular clothes. We've had these for about 2 months now, so I do think they've been worth it. I will purchase the next size up. It's hard to find a sleep sack for the winter, but that's not a 2.5 TOG, which I think would be too warm. I always worry about overheating. We keep her room between 67 and 70 usually at night in the winter and we find this TOG to be perfect. She never wakes up sweaty and she also never wakes up cold. These are also significantly cheaper than name brand sleep sacks.

Keeps my baby warm at night!
My baby recently transitioned out of having his arms zipped up in the LoveToDream swaddle sack, but he was too cold at night and it was disrupting his sleep. This Yoofoss sleep sack blanket is a DREAM! It’s so so so soft and has a nice weight to it (it’s not a weighted blanket, it’s just a thicker material than a cotton swaddle sack ). It is nice and wide at the bottom, so lots of room for growth and healthy leg movement during sleep. The colors are beautiful, and didn’t fade or shrink in the washer/dryer (I washed on cold and dry on low). The double zipper function is essential and the zippers are very smooth. I’m not saying this sack will solve all your problems, but I did notice my baby sleeps much more contentedly at night and I think it’s cause he’s finally warm enough! Plus he looks like the softest, sweetest angel as he sleeps 🩵

Sacos de dormir bonitos
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
User
Excelente producto
-Calientitos para el LEVE frío de la madrugada. -Mi bebé lo ha utilizado por 3 meses y aún le queda mucho espacio en las piernitas.-Por tener doble cierre, los cambios de pañal son súper sencillos.-Si ocurren accidentes, la tela exterior aguanta muchísimo y casi no deja pasar nada a la sábana o el colchón.
