Advertised as a Men's/Women's Beanie that was ‘One Size Fits Most’, you would expect it to be a reasonable size… it's not. In all honesty, it would be hard to say whether this would fit any Adult. It would be more accurate to tag it as a Kid's Beanie, at least they would be sure to ‘Fit’ it. This is significantly smaller than any other Beanie I've ever purchased, would be cautious to purchase another Beanie from Bioworld now. Very disappointed.
