Profile or Crown
A baseball cap profile refers to the structure or crown on the front of the cap above the brim.
There are generally four types of baseball cap profiles:
A) Structured–Standard high pro-crown profile
B) Mid crown profile
C) Mid to Low crown profile
D) Unstructured – Low crown profile
E) Pro round - round upper panels
It has a structured, steep profile and is typically featured with a flat visor.
Often thought of as the traditional baseball cap, it is usually structured, but has a slightly lower profile.
It is slightly less slanted and shallower than the Pro Mid but can be structured or unstructured.
It is either unstructured or lightly structured to lie closely to the head and is paired with a pre-curved visor.
It has premium dual-tone buckram and rounded upper panels that contour to rest securely on your head. It is featured with a slight pre-curved visor.
Closure Type - For ADJUSTABLE Caps
Adjustable baseball caps have closures on the back of the caps that allow you to adjust the size.
Types of closures:
A) Plastic snap
B) Adjustable hook / loop tape (Velcro)
C) Adjustable fabric tucks trap with slide closure
D) Leather strap Antique Brass or Silver Buckle and Grommet
FITTED Caps Are Not Adjustable
Fitted caps are not adjustable, since they are fitted to head sizes, and therefore do not have closure types, the back of a fitted cap is closed.
Panels are different pieces of fabric that make up the top of the cap, there are usually five or six panels in a baseball cap.
Baseball caps are generally made of cotton, cotton blends, jersey mesh, wool, acrylic/wool blends, and moisture wicking fabric.
Brim (Also known as bill or visor):
The brim of the cap is the piece that protects your face from the sun. It is usually made of plastic which is sewn inside the fabric.
Eyelets are small holes at the top of the cap that allow your head to breathe. They can either be metal or reinforced stitching.
The buckram of a baseball cap is the mesh liner inside of the front of the cap that provides the structure and form. Structured caps have buckram and unstructured caps have no buckram, giving them the more casual, lower profile.
