I was cursed at birth as every male relative of mine since the invention of photography has the same male pattern baldness: I've had a bald spot since 17, two landing strips since 21, and have shaved my head for the past decade.  Needless to say, I own hats.  I own lots of hats.  This is my favorite, for a number of reasons.
1) It isn't so long that I can't pull it all the way down.  So it sits fully on my head.  That is cool.
2) It is warm.  It has a fleece band but I really cant sense the difference in warmth between the fleece and non-fleece portion.
3) It actually stays on my head, even when I just shaved.  Most hats slide off in that condition, making me look like an idiot.  This one doesn't.
4) It looks good.  In fact, it looks awesome.

In summary, this hat does what it is supposed to; which is more than most hats can say.  I wish I knew how Chaos made this hat so it stays on freshly shaved heads.  Brilliant.
