Choosing a sun hat: how to find a comfortable style for the beach, travel and outdoor activities

A sun hat may seem like a simple accessory, but small differences can determine whether you wear it all day or tuck it into your bag after one walk. A hat that’s too loose can blow away, a brim that’s too narrow offers little shade, and an attractive fabric may be impractical in the rain or when you’re sweating.

So don’t just look at the colour or price. Pay particular attention to the fit, brim width, material and how the UV protection is specified. Below, you’ll find the key points to consider, along with a few styles for different uses.

Common sun hat pitfalls

1. Looking only for the term “UV protection”

“UV protection” on its own tells you little about the level of protection. Look for a specific rating, such as UPF 40+ or UPF 50+, and check which part of the hat it applies to. A wide brim can shade your face, neck and shoulders better than a narrow peak, but coverage also depends on how you wear it.

Claims about UPF and blocking UV radiation come from the brand’s product information. Treat them as product specifications to check, rather than a medical guarantee.

2. Choosing a one-size-fits-all hat without measuring your head

A sun hat that’s too tight will be less comfortable on long walks or cycle rides. One that’s too loose may shift in the wind. Measure the circumference of your head with a tape measure around the widest part, roughly above your eyebrows and ears. Compare your measurement with the stated size in centimetres, rather than relying on S, M or L alone.

An adjustable cord, buckle or hook-and-loop fastening can help, but it won’t make up for a poor basic fit.

3. Assuming a wide brim is always practical

A wide brim offers more shade, but it can flip up in the wind or restrict your vision while cycling. A wide brim that goes all the way around is often useful at the beach, while gardening or fishing. For walking or travelling, a foldable sun hat with a slightly more flexible brim may be more practical.

Also consider the weight and how easy it is to pack away. A style weighing around 60 to 75 grams is generally easy to carry, but the material and firmness of the brim still matter.

Key specifications to compare

UPF rating and brim width

A UPF 50 sun hat is generally described as a style whose fabric offers a high level of UV blocking under a particular test method. According to the product information from various brands, the stated protection can vary depending on the fabric, colour and construction. So check:

  • the stated UPF rating;
  • whether the brim goes all the way around;
  • whether it also covers your neck and ears;
  • whether the manufacturer says the protection remains after washing.

A wide-brimmed sun hat with a brim of around 7 to 16 cm can provide more shade, but a larger brim isn’t automatically better for every activity.

Material, ventilation and moisture

Polyester and nylon are lightweight, dry relatively quickly and can be suitable for an outdoor hat. Mesh panels or a sweatband can improve airflow. Linen feels cool and airy, but if you’re considering a linen style, always check whether it’s actually described as water-repellent or waterproof.

A waterproof sun hat can come in handy in changeable British weather. Check whether it has waterproof fabric, a membrane or just a water-repellent finish. These terms don’t mean the same thing.

Fit and stability

For walking, fishing and cycling, a chin strap or adjustable drawcord can be useful. A sun hat with neck protection provides extra coverage, while a detachable flap offers more flexibility. If you have long hair, look for a sun hat with a ponytail opening.

Frequently asked questions about sun hats

What size sun hat do I need?

Measure your head circumference in centimetres and compare it with the product’s size guide. If you’re between sizes, choose the larger one only if the hat has an adjustable cord, buckle or band. Also check that the size refers to the circumference, not the diameter.

How long does a sun hat last?

How long it lasts depends on how often you use it, how you wash it, how much sun it’s exposed to and how you store it. A hat worn every day for walking or fishing will wear out faster than one used occasionally for days at the beach. Follow the washing instructions: some styles can be washed at 30 °C, while others should only be cleaned with a damp cloth. Leave the hat to air-dry and store it somewhere dry. If the brim needs to keep its shape, avoid folding it for long periods.

Is a UPF 50 sun hat enough for outdoor use?

UPF 50 is a specific textile rating that, according to the product information, indicates a high level of UV blocking. However, coverage still depends on the brim, fit and how you wear the hat. So pair your sun hat with suitable clothing and avoid prolonged direct sun where possible. When buying, always check which parts of the product are actually covered by the stated UPF specification.
