I thought it was big, but it was just right
I bought it to put wet training clothes in. I struggled between M size and bought both. I thought L size would be too big, but surprisingly L was just right. The size was really hard to understand, so I wanted a picture of the model actually holding it.
Also, as others have mentioned, it doesn't become very compact when folded. Since the handles are sturdy, it took a bit of technique to fold it.
