Choosing men’s sportswear without regret: consider the material, fit and intended use

A new men’s sports T-shirt may look technical and comfortable in the photograph, but in practice, the purchase often comes down to the details. Fabric that becomes too warm, shorts that slip down or a waistband that digs in can make a garment less suitable for sport, travel or everyday wear.

When choosing men’s sportswear, there are three common pitfalls:

  1. Marketing language without clear material specifications
    Terms such as “breathable”, “quick-drying” and “moisture-wicking” mean little if the composition is not stated. Always check the percentages of cotton, polyester and elastane, as well as whether there are any mesh panels.

  2. The wrong fit for the activity
    A regular-fit men’s short-sleeved T-shirt is suitable for many situations, but feels different from men’s compression shorts or loose mesh shorts. Don’t look only at the size letter; check the chest, waist and length measurements too.

  3. Care instructions that do not suit the material
    Sportswear washed at high temperatures or treated with fabric softener can lose its shape or moisture-wicking properties more quickly. Before buying, check the care label and drying instructions.

The key features of men’s sportswear

1. Material and moisture management

For intensive training, many shoppers look for breathable sportswear that helps draw moisture away from the skin. Polyester is often used for lightweight, quick-drying clothing. Cotton feels soft and is comfortable for casual menswear, but can remain damp for longer when you sweat heavily.

A blend can be practical. According to the product description, the Under Armour Sportstyle T-shirt is made from 60% cotton and 40% polyester. The description also mentions a quick-drying finish and a lightweight construction. This information comes from Under Armour’s product details; it does not guarantee that every wearer will have the same experience.

For high-intensity activities, the construction is important too. Men’s mesh shorts with a 100% polyester outer fabric and lightweight lining may feel more breathable than heavy cotton shorts. However, check that the lining provides sufficient coverage for your activity.

2. Fit: regular, loose or compression

Fit determines how much freedom of movement and support a garment provides:

  • Regular fit: a classic cut that is neither tight nor loose. Suitable for training, walking and everyday wear.
  • Loose fit: extra room around the legs and hips. Practical for basketball, football, fitness or warm days.
  • Compression fit: close-fitting and designed to be worn as a base layer or for intensive training. Choosing one size larger may feel more comfortable if you prefer less pressure.

When in doubt, use the size guide. According to the stated measurements, size M in the Under Armour men’s T-shirt corresponds to a chest measurement of around 94–104 cm. Sizing may vary between brands, so always compare it with your own body measurements.

3. Details that affect everyday wear

Small features can make a real difference to comfort:

  • An elasticated waistband with a drawstring helps prevent men’s sports shorts from shifting during movement.
  • A soft, stretchy waistband can reduce irritation around the waist.
  • Flat or strategically placed seams are important during longer training sessions.
  • A zipped or secure pocket is useful for keys or a card.
  • A mesh lining can improve airflow, but check that the shorts are not see-through.

Also pay attention to care instructions. Some sports T-shirts can be washed cold and dried at a low temperature. For the Under Armour HG Armour Shorts, the product description states, among other things: wash with similar colours, do not use fabric softener and do not iron.

Frequently asked questions about men’s sportswear

Which men’s sportswear is suitable for fitness?

Choose a shirt with enough room for movement and a fabric that, according to the product specification, dries quickly. For the lower half, you can choose between loose men’s sports shorts for maximum freedom of movement or men’s compression shorts as a close-fitting base layer. Pay particular attention to the seams, waistband and pockets.

How can I stop sportswear from developing odours quickly?

Follow the care label, do not leave sweaty clothing scrunched up for long periods and avoid using fabric softener when the manufacturer advises against it. Claims about odour reduction should be understood as claims made by the brand about the product. For example, the Under Armour product description mentions odour-control technology; this is based on Under Armour’s own product information and is not a universal guarantee.

How long does men’s sportswear last?

Its lifespan depends on how it is used, how often it is washed, the material and the drying method. After buying, check whether the fabric retains its stretch, whether the seams remain secure and whether the waistband becomes misshapen. Clothing worn for both sport and casual use benefits from being rotated and washed according to the care label. This helps prevent unnecessary wear and keeps your collection of men’s boxers, T-shirts and shorts practical and ready to wear.
