An Under Armour men’s cap can be suitable for commuting, walking, training and everyday use. However, it is easy to choose a model that becomes uncomfortable after a short time. Marketing terms such as “sporty”, “breathable” and “moisture-wicking” mean little on their own if the size, material and care instructions are not clearly stated.
As a Joybuy Product Recommendation Officer, I therefore focus mainly on verifiable product information. For the Under Armour Sportstyle caps below, details including sizing, fabric composition, construction and care instructions are available.
An L/XL is not exactly the same size across every brand. With these Under Armour caps, the size is linked to a head circumference. L/XL, for example, is suitable for approximately 57.8 to 61.0 cm. According to the product information, XL/XXL ranges from approximately 59.7 to 63.5 cm.
Anyone who looks only at “L/XL” without measuring may buy a cap that feels too tight or is too loose.
A breathable cap does not necessarily have mesh panels. According to the product description, the Sportstyle models use a soft, structured knitted polyester fabric. This can be comfortable for everyday use, but it is not the same as an ultralight running cap with large ventilation panels.
A cap worn regularly during training will be exposed to sweat, dust and rain. The models mentioned are made from 100% polyester, but the care instructions specify hand washing or spot cleaning. Do not bleach, tumble dry, iron or dry clean. Incorrect treatment can damage the shape or fabric more quickly.
Measure your head circumference with a flexible tape measure approximately 2.5 cm above your eyebrows and above your ears. Keep the tape in contact with your head, but do not pull it tight. Then compare the result with these guidelines:
The cap has a stretch-fit construction. According to the product information, the fit is generally true to size. If you are between two sizes, the product information for some models says to choose the smaller size for a closer fit or the larger size for more room.
The UA Classic has a low-profile design with a structured front panel. This panel is designed to retain its shape and gives the cap the look of a classic men’s baseball cap. A pre-curved brim can be practical when walking, cycling or taking part in outdoor activities, as it partly shields your eyes from bright light.
Do consider the fit you prefer: a low-profile cap sits lower on the head than a model with a high crown. This is a matter of style and comfort, not a guarantee that the cap will suit every head shape.
The fabric composition is 100% polyester. The product description mentions a stretch HeatGear sweatband. According to Under Armour’s own product information, this sweatband is designed to wick moisture away from the skin. This is a brand claim; the practical experience may vary depending on the individual, temperature and level of exertion.
If you are looking for a moisture-wicking cap for training, it is sensible to also consider the fit, weight and care instructions. For everyday use, the embroidered logos, soft texture and classic shape may be more important than maximum ventilation.
Why it suits this profile: The S/M size is intended for a head circumference of 54.0 to 57.2 cm. The blue colour and embroidered logo complement a sporty everyday outfit.
The product page states a specific head circumference rather than just a general size label. The hand-washing instructions are also clearly provided.
100% polyester, a low-profile shape, a structured front panel and stretch in the sweatband, according to the product description.
Why it suits this profile: The midnight navy and white colour combination is easy to coordinate, while the L/XL size suits a head circumference of 57.8 to 61.0 cm.
The size is linked to centimetres, and the product information states that, if you are unsure, you can choose a smaller or larger size depending on the fit you want.

Why it suits this profile: This blue men’s cap offers a larger size option for head circumferences of 59.7 to 63.5 cm and is designed for sport, outdoor activities and everyday use.
The generous sizing prevents a larger head circumference from being squeezed into a stretch fit that is too small. The care instructions also help with regular use.

We have put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
Ideally, hand wash an Under Armour cap in cold water with a mild detergent. Leave the cap to air dry flat, away from direct heat. Do not use bleach, fabric softener or a tumble dryer. If the cap is damp, allow it to air before storing it. This helps reduce the risk of lingering odours and distortion.
Measure your head circumference above the ears and compare it with the size chart. S/M ranges from 54.0 to 57.2 cm, M/L from 55.9 to 59.1 cm, L/XL from 57.8 to 61.0 cm and XL/XXL from 59.7 to 63.5 cm. With a stretch fit, choosing between two sizes may depend on whether you want a closer or roomier fit.
The product descriptions mention a stretchy HeatGear sweatband, polyester fabric, embroidered logos and a design for training and outdoor use. According to Under Armour’s own information, the sweatband is intended to wick moisture away. For intensive sport, it is also worth checking whether the low-profile fit and all-polyester construction suit your preferences.
Follow the product instructions: hand wash with cold water and mild detergent or spot clean. Do not bleach, tumble dry, iron or dry clean. Allow the cap to air dry naturally and avoid direct heat.
