Purchased the Unisex Grey in Small - supposed to be 56cm but unlike the Arlo - this has a elastic sweatband - which doesn't pull the hat "inward" so the hat is closer to 57.5 cm.
Had to return it and get an Arlo instead which seems like the only hat that is 56cm
Always get compliments - so got the black one also this black friday.
The hat is elegant, sylish - and perfect for Bay Area winters as well... felt ones are too hot when the sun is out in this weather. So the Arlo is my all-year-around hat !
suggest add a couple more colors - esp. light grey !
