This is a one-piece type. My child used to run around in this even on cold, snowy days. It has been washed after use, so applying a waterproof spray before use (especially on the bottom) would make it great for playing in the snow. It's size 80, but my child wore it when they were size 90. This is a used item. Please refrain from purchasing if you are sensitive to used items or are concerned about home storage.
