Baseball cap crown types
Six panel caps: Six panel cap is the standard style with 2 triangles at the front attached to the bill, one on each side and two on the back
Five panel caps: 5 panel caps have one panel that stretches across the whole length of the bill which allows for a more decoration, plus 2 panels on the side and 2 on the back.
Low-profile : The least steep slant to the front of the hat and is normally associated with a sport or golf style cap
Mid-profile:a bit steeper slant to the front of the hat and is normally associated with what a baseball player would wear. Additionally, this style hat tends to be a bit of a deeper fit.
High-profile: almost a straight up slant to the front of the hat and normally associated with a “trucker” style cap.
Structured: A stiffer, supportive fabric inside helps structured baseball hats hold their shape if crumpled.This is a traditional style worn by professional baseball players.They are available in a number of colors and fabrics.
Unstructured: means that the two front panels of the hat are not supported —the hat is designed so that the two front panels “flop” flat when you set it on a table.
