This is a Montbell baby vest. There are no noticeable stains or marks, but there is some overall fading. It is a combination of gray and yellow. I received it as a hand-me-down, but it didn't fit, so I'm selling it. It can be used not only in winter but also in early spring and autumn when it's a little chilly, and it's recommended not only as outerwear but also as a single layer like a sleeper.
