Choosing men's sports shorts: how to find a pair that suits your training

Sports shorts may seem like a simple item of clothing, but you often only notice the difference between a comfortable pair and a poor purchase once you start moving. A waistband that is too tight can dig in, the wrong fabric can stay damp for a long time, and a pocket without a secure fastening is impractical when running. So, if you buy men's sports shorts online, it is worth looking beyond the colour and brand logo.

Three common pitfalls when choosing men's sports shorts

1. “Breathable” without clear information about the material

Breathable shorts can be comfortable during fitness sessions or running, but the term itself does not tell you much. Check the material and look for details such as mesh panels, lightweight woven fabric or moisture-wicking construction. Men's cotton shorts feel soft, but they are not always the most practical choice for intensive training because cotton can retain moisture.

2. A fit that does not match the product name

Compression shorts and regular-fit shorts do not feel the same. A compression fit should feel close and supportive. If you prefer more room to move, fitted or regular-fit shorts may be a better choice. Also check the inside-leg length: shorts measuring around 15 cm will fit differently from running shorts that are noticeably shorter.

3. Not paying enough attention to pockets and the waistband

Shorts with pockets are handy for keys, a card or your phone, but an open side pocket is not automatically suitable for running. Check whether there is an internal phone pocket, zip or other secure storage. An elasticated waistband with a drawcord also gives you more control over the fit, particularly during sprints, squats or cycling.

Important specifications to check before ordering

Material and moisture management

Polyester and elastane are widely used materials for training. Polyester is lightweight and generally dries faster than cotton. Elastane provides stretch, which is useful for movements involving a long stride or deep knee bends. A combination of both can work well for men's fitness shorts and men's training shorts.

Always check the exact composition. For example, the Under Armour Hg Armour Short is made from 84% polyester and 16% elastane; according to the product description, the mesh consists of 92% polyester and 8% elastane. The product information also mentions lightweight, quick-drying fabric and ventilation panels. These are product specifications, not a guarantee that every wearer will have the same experience.

For everyday wear or lounging, French Terry fabric may feel more comfortable. According to the product information, the PUMA ESS No. 1 Logo Short is made from 68% cotton and 32% polyester. This makes this type of men's cotton shorts an appealing option for relaxed activities, walking or casual wear.

Fit, size and freedom of movement

Measure your waist where you usually wear your shorts and compare the measurement with the size guide on the product page. Do not focus solely on S, M, L or XL. For the Under Armour Hg Armour Short, a waist measurement of 86 to 91 cm is listed for size L. The fit is compression, so it is designed to sit very close to the body. If you are between sizes or prefer less pressure, the product information suggests considering a larger size.

The Under Armour Launch 7'' 2-in-1 Shorts have a lightweight woven outer layer with built-in compression undershorts. The product description specifies a fitted cut. This offers a different balance of coverage and freedom of movement from loose-fitting shorts.

Length and intended use

  • Men's running shorts: shorter, lightweight shorts can feel comfortable in warm weather and when you want plenty of freedom of movement.
  • Men's 2-in-1 shorts: an outer layer with built-in undershorts provides extra coverage and support during running or intensive training.
  • Black sports shorts: easy to combine with other clothing and less prone to showing marks, but check the care instructions to help prevent fading.
  • Casual men's shorts: knee-length French Terry shorts are better suited to lounging, travelling and everyday wear than a close-fitting model.

Frequently asked questions about men's sports shorts

Which men's sports shorts are suitable for running?

Choose lightweight shorts with a fit that does not chafe and a waistband with a drawcord. For extra coverage, you could consider men's 2-in-1 shorts. An internal phone pocket or reflective details can be useful when running outdoors, but always check the exact product description.

Is polyester or cotton better for sports shorts?

It depends on how you plan to use them. Polyester is generally lightweight and is often used for breathable and quick-drying shorts. Cotton feels soft and works well for casual men's shorts, lounging and relaxed activities. For intensive sessions, the fibre composition matters more than the brand name alone.

How can you stop sports shorts from losing their shape quickly?

Follow the care label, do not use fabric softener if it is not recommended, and avoid high drying temperatures. Wash sports shorts inside out if instructed by the manufacturer. Also check the composition before buying: elastane can provide stretch, but the recommended care routine remains crucial for maintaining the fit.
