What Are the Parts of a Baseball Cap Called?

A baseball cap is made up of several key parts, each serving a functional and aesthetic purpose. Here’s a breakdown of the common components:

Main Parts of a Baseball Cap

1. Crown

• Definition: The top part of the cap that fits over your head.

• Details: Made up of several panels (usually 5 or 6) stitched together.

• Types:

  • Structured: Has a stiff fabric or buckram inside to hold its shape.

  • Unstructured: More relaxed and moldable to the head.

2. Panels

• Definition: Fabric pieces stitched together to form the crown.

• Common styles:

  • 6-panel: Traditional baseball cap.

  • 5-panel: Popular in streetwear; has a flatter front.

3. Visor / Brim / Bill

• Definition: The stiff projecting part that shields your eyes from the sun.

• Styles:

  • Curved brim: Traditional sporty look.

  • Flat brim: Modern, urban style.

4. Button (Squatchee)

• Definition: The fabric-covered button at the very top where the panels meet.

• Purpose: Mostly decorative.

5. Eyelets

• Definition: Small holes (embroidered or metal) near the top of each panel.

• Purpose: For ventilation.

6. Sweatband

• Definition: The inner band along the base of the crown, inside the cap.

• Purpose: Absorbs sweat and provides comfort.

7. Underbrim

• Definition: The underside of the visor.

• Options: Can be same or different color; sometimes has print/design.

8. Closure / Back Strap

• Definition: The mechanism at the back that adjusts the fit.

• Types:

  • Snapback: Plastic snaps.

  • Strapback: Fabric strap with buckle or slide.

  • Velcro: Hook-and-loop fastener.

  • Fitted: No adjustment – exact size.

9. Seam Tape

• Definition: Inside the cap, covers the seams where the panels join.

• Purpose: Adds durability and neatness.

10. Front Panel Backing (for structured caps)

• Definition: Stiff material behind the front panels.

• Purpose: Keeps the front shape firm for embroidery/logos.

If you're customizing or producing baseball caps (e.g., for branding or uniform purposes), knowing these parts helps when choosing materials, designs, and printing/embroidery methods.
