Diagram of Baseball Cap Parts / Illustrated Guide to Baseball Cap Components

This article will take you deep into the anatomy of a baseball cap, exploring the names and functions of its various components, along with some interesting background knowledge.

A standard baseball cap is primarily composed of the following parts:

Crown: The crown is the main part that covers the top of the head and forms the foundation of the cap's shape. The silhouette of the crown determines the type of baseball cap. It is mainly categorized into Low Profile, Mid Profile, and High Profile. Low Profile crowns sit closer to the head for a more understated look, while High Profile crowns offer more headroom and a more classic shape.

Panels: Panels are multiple triangular fabric pieces stitched together to form the crown. The most common design is the 6-panel cap, though 5-panel or 8-panel designs also exist. More panels result in a rounder crown shape. Fewer panels (such as 5) mean fewer seams at the front, providing a smoother "canvas" for forehead logos.

Button: The button is the knob located at the very top of the crown. Its original purpose was to secure the convergence point of all the panel stitches, providing reinforcement. Today, it has become an important design detail, with buttons of different colors and materials reflecting the brand's style.

Visor (or Peak/Brim): The visor is the most iconic part of a baseball cap. It is typically embedded with a piece of cardboard or plastic to maintain its stiffness. Its primary function is to block sunlight and rain, and its curvature varies according to personal preference and fashion trends

Eyelets: Eyelets are small holes on the panels designed for air circulation, helping to dissipate heat and sweat. These holes can be punched needle holes or embroidered faux eyelets, which are mainly decorative and commonly found on caps from fashion brands.

Sweatband: The sweatband is a padded strip along the inner edge of the cap, usually made of pure cotton fabric. It absorbs sweat, enhancing comfort and stability during wear. High-quality sweatbands are made of thick, soft-feeling fabric and effectively prevent sweat from seeping into the outer material.

Buckram: The buckram is a stiff material hidden inside the front panels. It acts as the "skeleton" of the cap, ensuring that the area above the visor remains upright and does not sag. This is particularly crucial for areas where logos are embroidered.

The following is additional knowledge about adjustment systems and styles:
