What defines a snapback?

A true snapback has three core traits. First, the adjustable snap—two plastic bands that click together and shift through notches so you can loosen up for a high ponytail or cinch down for windy days. Second, a structured crown with a reinforced front panel that helps the hat hold its shape. Third, a flat bill out of the box (you can give it a soft curve if that suits your face). That combination makes logos read cleanly, adds a bit of height for presence, and avoids the sloppy collapse you sometimes get with unstructured caps.
