Pit to pit: approximately 41cm Length: approximately 58cm Although it's labeled XS, it's J.S, so I'm listing it as a Japanese size S. 100% polyester Pocket on the right side (image 7) The upper back lining is yellow-green mesh with ventilation. The contrast of orange and yellow-green is very cute. It was quickly outgrown, so it's in good condition, but please understand that it has been stored at home before purchasing. Color: Orange
