This is a mushroom-patterned, mesh swaddle for summer. The M size was used for about a month, and the L size was washed but never worn and has been stored. While using these, my baby would self-soothe just by wearing them. These are top-ranked items on Rakuten. Made of 100% cotton, gentle on babies. - Sizes: M, L (one of each) - Design: Mushroom pattern Thank you for looking.
