I bought the coal heather and the black versions for myself and my husband.  The coal heather seems a bit smaller for some reason...but still big enough, not too small by any means.  I will say these hats seem considerably warmer than the standard Carhartt hats we had before, they're thicker and seem heavier...overall just a better quality hat.  The $5 extra for this vs the original is totally worth it in my opinion.  Very warm for dead of winter in ND & MN!
