Choosing men’s sports shorts: how to find a comfortable and functional fit

A good pair of sports shorts should do more than just look sporty. They should stay comfortable during squats, running or a walk, without the waistband digging in or your phone falling out of an open pocket. However, there are several common pitfalls to avoid when buying men’s sports shorts.

Common mistakes when buying sports shorts

1. Choosing a fabric that does not suit the intended use

Cotton feels soft and is suitable for everyday wear, warm-ups and relaxing. During intense training, however, cotton sports shorts can retain moisture for longer than synthetic fabric. This can make them feel heavy or clammy.

Conversely, technical fabrics are not everyone’s preferred choice for leisurewear. So start by considering how you will use them: are you looking for cotton sports shorts for wearing at home and casual occasions, or breathable sports shorts for fitness and running?

2. Looking only at the size letter

An M or L is not the same across every brand. Check the stated waist measurement, hip measurement and inside-leg length. A regular fit offers more room around the leg, while a compression fit sits close to the body.

Also check whether the waistband has a drawstring. An elasticated waistband without an adjustable fastening can shift during movement, especially when you are carrying your phone or keys.

3. Confusing marketing terms with practical features

Terms such as “quick-drying”, “supportive” or “odour-control” only tell you something useful when the product description also specifies the material and construction. According to Under Armour’s product information, certain models feature moisture-wicking fabric, mesh panels or odour control. These are garment features as described by the brand; the experience may vary depending on the wearer and activity.

Also look out for details that make a difference every day: the number of pockets, a phone pocket, reflective elements and the length of the shorts.

Important specifications to check

Material: cotton, fleece or technical fibres?

The fabric composition provides a useful first impression:

  • Cotton blend: soft and suitable for everyday wear, warm-ups and light training.
  • French Terry: according to the product description, this fabric has a smooth outer surface and a softer inner surface. It is well suited to comfortable training shorts and casual wear.
  • Fleece: a brushed inner surface can feel warmer. Men’s fleece shorts are particularly suitable for cooler days, warm-ups and relaxing.
  • Polyester with elastane: often used to provide freedom of movement and moisture-wicking properties. The fit can be close, especially with men’s compression shorts.

One example is the PUMA ESS No. 1 Logo shorts, made from 68% cotton and 32% polyester. According to the product information, this model is made with at least 50% recycled materials. This is a verifiable material specification, but it does not guarantee a longer lifespan.

Fit and length

Knee-length shorts are versatile for everyday wear, fitness and warm-ups. A shorter model with an inside-leg length of around 15 cm provides greater freedom of movement and is suitable for more intensive training. With a 2-in-1 model, the inner layer is particularly important to how the shorts feel during movement.

If you are unsure, choose a model with:

  1. An elasticated waistband.
  2. An internal or external drawstring.
  3. A length that does not rub against the knee.
  4. Enough room around the hips and thighs.

Pocket design and care

When it comes to sports shorts with pockets, the number of pockets is not the only thing that matters. Check whether a pocket closes, where it is positioned and whether it can accommodate a phone. An open side pocket is useful for keys during a short walk, while an internal phone pocket is better suited to running.

Care instructions also affect how well the shape and colour are maintained. For the models mentioned, PUMA recommends, among other things, washing inside out, washing with similar colours and avoiding dry cleaning. Under Armour states for various models that they should be washed cold and that fabric softener should be avoided. Always follow the label on the specific product.

Frequently asked questions about men’s sports shorts

Which men’s sports shorts are suitable for running?

Choose a lightweight model with a moisture-wicking outer fabric, enough room for movement and a secure pocket for your phone or key. 2-in-1 running shorts can provide additional coverage thanks to their close-fitting inner layer. Reflective details are practical when training outdoors in low light.

Are cotton sports shorts suitable for fitness?

That depends on the workout. A cotton blend is comfortable for strength training, warm-ups and everyday wear. For long or intensive sessions, synthetic, breathable sports shorts may feel more comfortable, as they are described in the product information as helping to move moisture away more quickly. Always check the exact fibre composition.

How do I choose the right size?

Measure your waist around its natural position and compare this with the brand’s size chart. Also consider the fit: regular fit offers more room, fitted sits closer to the body and compression fit feels very tight. If you are unsure, the drawstring and the product-specific sizing instructions are more important than the size letter alone.
