Common sun hat materials include polyester, straw (including paper straw), and nylon. These materials are used across different styles and can affect the hat’s weight, packability, and feel.

Brim widths typically range from about 3 inches up to 4.9 inches, with many common sizes around 3–4.5 inches.

Many listings specify UPF 50+, which blocks roughly 98% of harmful UVA and UVB rays.

Care varies by style: many hats list hand wash and either line dry or lay flat to dry, while straw options typically recommend spot cleaning or wiping with a damp cloth.

Many designs include breathable mesh panels or vents and moisture-wicking sweatbands to increase airflow and reduce sweating.
