A cap may seem simple to buy, but small differences can determine whether you wear it every day or leave it in the wardrobe after a few weeks. When shopping for men's caps, you'll also come across terms such as “UV protection”, “breathable” and “waterproof”, without it always being clear what they mean for you.
The most common buying mistakes come down to three pitfalls:
By checking the size, fit, material and care instructions, you can make a more informed choice between a baseball cap, sports cap, sun hat, beanie or another unisex style of headwear.
Use a soft tape measure around your head, just above your ears and about two centimetres above your eyebrows. Keep the tape comfortably against your head without pulling it tight.
Many adjustable caps fit a head circumference of around 56–60 cm. Other styles come in fixed Flexfit sizes, such as S/M or L/XL. Always check the size guide for the specific product. A “one size” label doesn't guarantee a fit for every head circumference.
Pay attention to the fastening, too:
Cotton caps are popular for everyday wear thanks to their soft feel and casual look. However, cotton can hold on to moisture for longer than technical synthetic fabrics. For running, cycling or walking, polyester, mesh and a sweatband are often more practical choices.
A breathable cap usually has ventilation holes, mesh panels or a moisture-wicking inner band. That doesn't mean every cap with holes will stay comfortable during intense exercise. Check the sweatband material, too, along with the amount of ventilation at the sides and back.
Linen can feel light and airy in warm weather. Nylon is often used for sun hats and outdoor caps because it's lightweight and may have water-repellent properties. Always check the care instructions for each product: some styles can go in the washing machine, while others should only be hand-washed.
A manufacturer may give a product a UPF rating. According to the relevant manufacturers' product descriptions, some Li-Ning styles are rated UPF 100+, while one TOP-EX style is listed as UPF 50+. Another TOP-EX style is listed as UPF 40+. Treat these as product specifications from the manufacturer, not as a general guarantee of full protection for your head, face or neck.
A cap with a neck flap covers more skin than a standard baseball cap and can be practical for fishing, boating, gardening or walking. Check whether the flap is detachable and how to store it when you want to wear the cap in its standard shape.
“Waterproof” is another claim to consider carefully. According to the product description, one TOP-EX style is made from nylon and designed for rain and outdoor activities. Another cap is described as water-repellent. This isn't the same as long-lasting protection in heavy rain. Check the fastening, seams and care instructions to avoid disappointment.

We've put together a complete, up-to-date list of products that meet these strict selection criteria and the applicable European safety regulations.
A baseball cap is suitable for everyday wear and light protection from the sun and glare. For running, a lightweight running cap with ventilation and a sweatband makes more sense. A cotton style works well with a casual look, while a nylon sun hat is better suited to travel and outdoor activities.
In cold weather, a winter hat or beanie is a practical alternative. Consider the fit: a deep, stretchy beanie covers your ears better, but may feel warmer than a thin knitted style. According to the product descriptions, some The North Face beanies are made from recycled polyester fibres or acrylic yarn. Always check the current composition on the product label for the style you choose.
Measure your head circumference above your ears and compare the result with the product's size guide. Keep the fit in mind: a Flexfit style fits differently from a cap with an adjustable strap or drawcord.
It depends on the style. Some caps are listed as machine-washable, while Li-Ning and various TOP-EX styles should be cleaned with a damp cloth or by hand according to the product information. Always follow the care label to preserve the shape, colour and fastening.
Look for a lightweight design, ventilation holes, a sweatband and a secure fit. A breathable sports cap can be practical for running. For walking or fishing in bright sunshine, a sun hat with a neck flap can provide more coverage. Check UV protection claims with the manufacturer and don't treat them as a substitute for other sun protection measures.
