It's a nice stretchy beanie.  I wouldn't call it a "slouch" fitting hat as someone else described.  For a normal adult head, it fits nicely, covers the ears and has enough elastic-stretch to stay on your head, comfortably.  I purchased this to wear outdoors at a St. Patrick Day fundraising event to be festive and warm.  Cute.  Will do the trick.  Arrived quickly.  Thanks.
