Perfect extra layer, soft cotton
Love this sack! Softer with more washes and the perfect extra layer on top of sleepwear for nap time. The print is super sweet too - saw it comes in a larger 4-layer muslin blanket as well on company website 🐑 💛

Cute sleeping sack, lightweight
I have the swaddle blankets from this same brand which I already like and used in the first months, so I decided to try the Muslin sack too since it's basically the same thing a swaddle blanket that zips, but it can be used up to 6 months. I put her in the sack with a long sleeve onesie and socks. It's a light material and it zips from the bottom so I don't disturb her too much during diaper changes when she's asleep.

Hardware needs improvement
We bought this sleeping sack for the summer. The muslin fabric is lightweight and just what we needed. I like the two way zipper design, and that they added a button to hold the zipper in place. However, the quality of the button and the zipper is not great. The zipper is hard to zip on without catching the fabric, which is not ideal for a quick mid-sleep diaper change.
