The New Era 9FIFTY A-Frame is a classic, adjustable throwback cap that started on the West Coast of the US and has taken over the world. Unlike the regular 9FIFTY cap, the A-Frame has 5 panels with a peak at the front instead of 6-panels. It is a structured cap with a squared, flat visor that has the ability to curve. The 9FIFTY A-Frame has a full crown. The back panels are opened up to allow for an adjustable plastic snap or strapback to be inserted.
