This swaddle is made of 100% cotton gauze fabric, which feels gentle on the skin. It's designed so you can take the hands out by unbuttoning it. I used it for about a month, starting in May of this year. My baby has outgrown it, but it's still in good condition, so I'm selling it. There is a small stain on the right hand part. *See photo 3 Size: S (0-3 months) Thank you for looking.
