Choosing outdoor hats and caps: a practical buying guide for sun, rain and wind

An outdoor hat or cap may seem simple to choose, but there are big differences in fit, material and protection. A cap that feels comfortable on a short walk can become too warm on a long bike ride. A wide-brimmed sun hat may offer better protection from bright sunlight, but it can shift in the wind without a chin strap.

So if you’re looking for outdoor hats and caps, it’s worth looking beyond colour and style. Pay particular attention to the conditions you’ll be wearing your headwear in. Below, you’ll find the key points to consider, common pitfalls and a few product suggestions for different uses.

Three pitfalls to avoid when choosing outdoor headwear

1. A UV claim without clear details

Terms such as “sunblock” or “UV protection” don’t tell you much on their own. Check whether a specific rating is given, such as UPF 40+ or UPF 50+, and see how much of your head and neck the brim covers.

A wide brim can provide extra shade for your face, ears and neck. A classic outdoor cap with a short peak mainly protects your eyes and forehead. According to PELLIOT’s own product information, the UPF50+ yarn used blocks at least 92% of UV rays. Other models list a UPF 50+ rating, but the actual coverage also depends on the design and how you wear the hat.

2. Assuming “waterproof” means suitable for prolonged rain

A waterproof cap or hat can be useful in a shower, but check the seams, fastening and ventilation too. A product may have a water-repellent outer fabric without being designed for prolonged rainfall.

Also check the care instructions. Some models can only be hand-washed. Others can be washed on a delicate 30 °C cycle, but must not be tumble-dried or ironed. Incorrect care can damage the shape, coating or fit.

3. Focusing only on head circumference

A cap can be the right size and still feel uncomfortable. Crown height, peak shape and adjustability all play a part. Measure your head circumference with a flexible tape measure just above your eyebrows and ears. Compare the measurement with the size chart for the specific product.

An adjustable cap with a buckle, drawcord or strap is handy if you fall between sizes. A Flexfit model with an elasticated band can feel comfortable, but it doesn’t offer the same personalised adjustment as a cap with a buckle or drawcord.

Key features to look for in outdoor hats and caps

UV protection and brim width

For trips to the beach, walking or fishing, a UV-protective hat with a wide brim is a sensible choice. Product information describes a UPF 50+ hat as having a high level of fabric protection. Check whether the brim also covers the sides of your face and your neck.

A fishing hat, bucket hat or sun hat with an all-round brim will generally provide more shade than a baseball cap. A cap with a neck flap adds coverage at the back without the need to wear a full wide-brimmed hat.

Ventilation and moisture management

For running, golf and walking, mesh panels, ventilation openings and a moisture-wicking sweatband are useful features. A breathable sports cap made from polyester or a synthetic blend can dry quickly, while linen can feel comfortable in warm weather.

Check the fabric composition. “Breathable” isn’t a fixed technical standard, so look for specific details such as side mesh, an open top or a sweatband. If you’ll be wearing the cap for vigorous activities, it’s also important that it stays securely in place as you move.

Fit, weight and packability

A lightweight style is handy for travelling and camping. A packable sun hat takes up little room in a rucksack, but should regain its shape after unpacking. A chin strap or adjustable drawcord helps keep it in place in windy conditions, especially when cycling, boating or walking along the coast.

For cold weather, a winter hat in stretchy knit is more suitable than a thin summer cap. Look for coverage over the ears, a lining and suitable material. A knitted hat retains warmth, but may feel hotter than a lightweight cap during exercise.

Frequently asked questions about outdoor hats and caps

Which outdoor cap is suitable for rain?

Look for a model whose product information specifies a waterproof outer layer or membrane. Check the care instructions and whether it keeps its shape, too. A waterproof cap is most practical in light to moderate showers; for prolonged rain, you’ll usually need additional waterproof clothing.

Is a UPF 50+ hat always enough to protect you from the sun?

A UPF 50+ rating refers to the fabric’s protection according to the product information, but overall coverage also depends on the brim, fit and how you wear it. A wide brim or neck flap can cover more skin than a short peak. If you’re in the sun for a long time, follow general sun-safety advice as well.

How do you clean an outdoor hat or cap?

Always follow the care label. Some models can be machine-washed at a low temperature, while others should only be hand-washed or cleaned with a damp cloth. Ideally, leave your hat or cap to air-dry, and don’t use bleach unless the care instructions allow it.
