Hats and Caps for Sun and Weather

Sun cover: brim, UPF and neck flaps

For sun protection, the hat's shape matters as much as the label. A brim of about 7.5 cm (3 inches) or wider shades the face, ears and neck, while a baseball cap leaves the ears and neck exposed. UPF 50+ means the fabric lets through about one fiftieth of UV rays, which is a common target for fishing and hiking hats. A neck flap adds cover for the back of the neck.

A visor keeps the sun off the face while letting heat escape from the top of the head, which some people prefer on hot days or for running and golf. Its downside is that it leaves the scalp uncovered, so it works best with sunscreen on exposed skin. Wide-brim styles with a chin strap stay put in wind, which matters on a boat or a trail.

Fit, fabric and style

Head size is measured around the forehead in centimeters, and the number in the listing is the circumference. One-size hats often list a range such as 57 to 60 cm, and an adjustable strap or drawcord widens that range. For children, check the age range, since child sizes are smaller than adult hats and often elastic. If you are between sizes, choose the larger one and tighten the strap.

Cotton breathes and feels soft, while polyester and nylon dry quickly and pack flat. Trucker hats use mesh at the back for airflow, bucket hats pack easily, and balaclavas cover face and neck in cold wind. Look at the care label: some fabrics must be hand-washed to keep their shape.

Questions about Hats and Caps for Sun and Weather

How do I measure my head for a hat?

Wrap a soft tape measure around your head just above the eyebrows and ears. Compare the number in centimeters with the listing's size range, and choose a hat with an adjuster if you are between sizes.

Does UPF protection wash out?

Protection built into the fabric weave stays, while some treatments fade with washing and wear. Follow the care label, and replace a hat when the fabric is stretched thin or worn.

What is the difference between a trucker hat and a baseball cap?

A trucker hat has a mesh back for ventilation, often with a foam front. A baseball cap is made from solid fabric all round. The mesh keeps you cooler in the heat.
