brims

Brim refers to the projecting edge or lip that forms the outer circumference of many objects, most commonly the edge of a hat. On a hat, the brim extends horizontally from the crown and is designed to shade the face, eyes, and neck from sun, wind, or rain. The term can also describe the outer edge of other items, such as cups, bowls, or geological features where it denotes a lip or rim.

In hat design, brims vary by width, stiffness, curvature, and shape. Common categories include narrow, medium, and wide brims, with straight, rolled, or upturned profiles. Brims are made from materials such as straw for sun hats, felt for fedoras and dress hats, wool, and synthetic fibers. They are typically attached to the crown and reinforced with internal bands, wires, or other stiffeners to help maintain shape.

Care and maintenance depend on material. Straw brims can be crushed or warped if bent when wet, so many straw hats are shaped while damp and air-dried. Felt brims may be reshaped with steam and gentle pressure. Wool or synthetic brims should be protected from excessive heat and stored to prevent deformation. Proper storage, avoiding crushing, and cleaning according to material type help extend the life of a hat’s brim.

In addition to headwear, brims describe the rims of other objects, such as the edge of a cup or bowl, where the brim contributes to the object’s function and aesthetics.
