Toque is the Canadian word for Beanie.  And since a beanie keeps your head warm on a cold day, and hides your hair on a bad-hair-day - that's exactly what a Toque does.  Just in a more "Canadian" way.  The SO tag is visible worn as a cuff, or as a "slouch" - without a cuff.  You get to decide.  And look good while doing it.
