A baseball cap may seem like a simple accessory, but small differences can determine whether you wear it every day or leave it in the wardrobe after a few outings. The wrong size can feel tight, a fabric that doesn’t breathe well can get warm, and a promising UV or water-resistance claim won’t always tell you what you need to know in practice.
This buying guide helps men and women in the Netherlands compare baseball caps for everyday wear, sport, running, walking, fishing, golf and travel.
A men’s cap or unisex cap may look good but still feel too loose or too tight. So don’t just look at the colour and logo. Check the head circumference, fastening type and whether the cap is adjustable. An adjustable cap with a strap or drawcord will usually give you more flexibility than a closed model with an elasticated fit.
A rating such as UPF 40+ or UPF 50+ is a technical classification of the product according to the manufacturer. According to TOP-EX’s product description, one particular model has UPF 50+; according to Li-Ning’s product description, its running cap has UPF 100+. These ratings relate to the material and don’t replace general sun protection, such as seeking shade or covering your skin.
Also consider how much coverage you need. A standard baseball cap mainly protects your head and eyes from sunlight. A cap with a neck flap covers more of your neck, but may feel warmer.
A waterproof or water-resistant cap can be useful on a walk or bike ride, but always check the care instructions and the exact product description. A mesh sports cap is designed mainly for ventilation and quick drying, not necessarily for rain protection. For prolonged showers, a cap alone is generally no substitute for proper waterproof clothing.
Measure your head with a flexible tape measure, about 2.5 centimetres above your eyebrows and ears. Don’t pull the tape tight. Many models fit within these ranges:
A cap with a drawcord, buckle or strap is handy if several people will be sharing it. A Flexfit model works differently: the elasticated band adjusts within the stated size range, but offers fewer adjustment options than a classic adjustable cap.
A cotton cap often feels soft and works well for everyday wear. However, cotton can hold on to moisture for longer than synthetic sports fabrics. Polyester is widely used for sports caps, running caps and breathable caps because it’s lightweight and quick-drying. Ventilation holes or mesh panels can improve airflow.
According to the product descriptions for some TOP-EX models, linen is lightweight and breathable. These models are designed for warm-weather outdoor activities, but check whether the specific cap is machine washable. Products with embroidery or a special coating may sometimes need hand washing or spot cleaning.
Look at these three separate features:
Always consider claims about UV protection or waterproofing alongside the material, fit and care instructions. Don’t rely on a marketing term as your sole reason for buying.

How long your cap lasts depends on its material, how often you wear it and how you clean it. Always follow the care label for the specific product. Keep these points in mind:
Choose a lightweight running cap with breathable mesh, a sweatband and a secure fastening. A reflective strap can be especially useful in low light. Also check whether the model needs to be hand washed.
Measure around your head, above your ears and eyebrows, without pulling the tape measure tight. Compare the result with the manufacturer’s size chart. If you’re unsure, an adjustable cap will often give you more flexibility than a closed model.
Follow the care label. Many sports caps and models with structured panels will keep their shape better if hand washed or spot cleaned. Leave the cap to air dry and avoid harsh products, high temperatures and prolonged direct sunlight.
