      Super soft

      I was so impressed and excited to feel how soft and buttery the sleep sacks were! I really wanted to find a larger replacement for my growing toddler and the size of the XL was great but it shrunk with first wash.

      Obsessed with this sleep sack!

      I had been using a sleep sack that swaddled my baby’s hands, but with him rolling we needed a new option. I was nervous switching him would disrupt his sleep but this sleep sack is amazing! It’s so soft and thick and hugs him in the right places so he feels like he’s still being snuggled! We’ve been using it for well over a week and he’s finally sleeping through the night!!!!!!

      Mesh sleep sack and cotton sleep sack

      My baby has been using Sunday hug zip swaddle since she was born. She used the mesh zip swaddle and cotton zip swaddle.
      As she’s about to roll, I am transitioning her to sleep sack. The mesh sleep sack feels itchy to the skin when I tried on my own skin, even after washing with baby detergent. I’m a little disappointed that it is not smooth and soft.
      The cotton sleep sack feels soft and smoother to the touch and looks thin enough for Singapore’s humid weather when it’s cold.

      Will purchase the cotton sleep sack again!

      Dear Thea,

      Thank you for reviewing our Baby Sleep Sack. We're very happy that you like our Swaddle too.

      . . . . . . . . . . . . . . . . . . . . . . . . . .

      In regards to the Mesh Sleep Sack, we created it in a way that it would be soft and breathable on a baby's skin. It's made from 100% premium Korean cotton.

      Just like our Mesh Swaddle, the fabric helps regulate body temperature so your baby will not sweat much and get heat rash and skin irritation even during the night. It is our first time to receive a comment about the texture and softness.

      All our products have completed the Self-regulatory Safety Certification Test conducted by the Certification Examination Institute in Korea. These are free from harmful chemicals that would cause danger.

      Obsessed ❤️

      My daughter’s favorite thing to wear! She usually never likes being wrapped in a blanket but she’s been loving this sleep sack.


      My baby hasn't tried it yet but I think it's going to be useful!


      I bought it right away when I saw it. It's good that it won't come off when kicked.

      Oh so cozy 🤍✨

      The triple layer bamboo sleep sack is ✨EVERYTHING✨ I’ve been searching for and more. I love that this sleep sack is made of quality bamboo material, so you know it can be washed often without fabric pilling or other signs of wear including staining. I’m so happy with the thickness of the material - I wholeheartedly trust this to keep my toddler all bundled up and warm throughout the winter season. So in love with this!!🤍


      I like the moderately soft material. I bought it to use instead of a quilt for sleep education.


      My sleep education teacher recommended this sleeping bag, so I bought it!! My baby slept very well on the second day of sleep training, whether it was because she wore this or because the education was good haha. This prevents my baby's feet from getting cold.
