This is a rain coat from MUJI that is designed to fit over a school backpack (randoseru). It has a gusset on the back, and you can unbutton the gusset to wear it over a backpack. When not using a backpack or rucksack, you can button it up and wear it as a regular raincoat. It's compact and can be stored, so you can keep it in your backpack in case of rain. I had it prepared, but my child didn't want to wear it, so I think it was only worn a few times. However, since some time has passed, the vinyl part seems to have deteriorated slightly. Please check the photos for where the name was erased. Please refrain from purchasing if you are concerned about minor scratches or stains due to it being a used item. It will be shipped folded. #MUJI #SchoolBackpackRaincoat
