Buying men’s shorts: how to choose the right style for sport, swimming and leisure

Choosing a new pair of shorts may seem straightforward, but men’s shorts vary considerably in material, fit and intended use. A pair that feels comfortable on the sofa will not necessarily perform well during a workout or swim. So don’t focus only on colour and brand name. In practice, the fabric composition, waistband and length often matter much more.

As a Joybuy Product Recommendation Officer, I filter product information according to verifiable features. This helps prevent an attractive product photo or a general marketing claim from making the decision for you.

Common pitfalls when choosing men’s shorts

1. Using one pair for every activity

Men’s cotton shorts are often comfortable for everyday wear, but cotton absorbs moisture and generally dries more slowly than polyester. For running, fitness or intensive training, men’s sports shorts made from a lightweight synthetic fabric are usually more practical. Men’s swim shorts have different features again, such as a lining, drawstring and material designed for use in water.

2. Looking only at the size letter

A size L is not the same across every brand. Always check the waist measurement, hip measurement and inside-leg length where these are provided. The fit also makes a difference: a regular fit feels different from a loose mesh short. For example, the Under Armour Rival Fleece Shorts list a waist range of 86–94 cm for size L. The PUMA size chart uses German, British and American size notations, among others. Compare your own measurements with the chart instead of simply ordering your usual size.

3. Choosing an elasticated waistband without an adjustment option

An elasticated waistband is convenient, but the level of stretch can vary from one style to another. Shorts with both an elasticated waistband and drawstring offer additional adjustability, particularly when walking, cycling or exercising. Also check whether the drawstring is on the inside or outside and whether the pockets are large enough for keys or a phone.

The key specifications explained

Material: cotton, fleece, polyester or mesh

  • Cotton blend: feels soft and works well for casual men’s shorts, lounging and everyday wear. According to the product information, the PUMA ESS No. 1 Logo models are made from 68% cotton and 32% polyester.
  • Fleece: the Under Armour Rival Fleece Shorts are made from 80% cotton and 20% polyester. The product description mentions a brushed inner side. This makes this type of men’s training shorts suitable for warm-ups, the gym and cooler days, but less suitable for swimming.
  • Polyester: lightweight and suitable for men’s swim shorts, men’s running shorts and many training styles. According to the product details, the Reebok Yestin and Yale are made from 100% polyester, including the lining.
  • Mesh: men’s mesh shorts are designed to promote airflow and freedom of movement. The Stripes Mesh Shorts have a polyester outer fabric and lining. The loose fit is useful for basketball, football or casual summer outfits, but may feel roomier than a regular-fit style.

Pay attention to phrases such as “wicks away moisture” or “keeps you cool”. For the PUMA woven shorts, this is linked to dryCELL technology. This is a claim from PUMA’s product description, not an independently verified result. So also look at the specific fundamentals: 100% polyester, mesh construction, length and waistband finish.

Length and fit

A knee-length pair of shorts provides more coverage and is often suitable for casual wear. A style that sits above the knee generally offers greater freedom of movement during training. A loose fit provides more room around the thighs and hips, while a regular fit sits more evenly against the body.

When in doubt, check:

  1. The stated inside-leg length.
  2. Whether the shorts sit above, on or below the knee.
  3. Whether the waistband lies flat without digging in.
  4. Whether the pockets stay in place while you move.

Washing instructions and everyday care

Longevity depends not only on the fabric, but also on how the shorts are washed. Always follow the care label. According to the product information, the PUMA woven shorts can be washed at 30 °C on a delicate programme and must not be tumble-dried. The Reebok swim shorts are also intended to be washed at 30 °C and must not be ironed or tumble-dried.

After wearing swim shorts in chlorinated or salt water, rinse them with clean water where possible. This is a simple way to remove residue from the fabric. For sports shorts, use detergent for coloured clothing if the label recommends it, and avoid fabric softener when advised against by the manufacturer.

Frequently asked questions about men’s shorts

Which men’s shorts are suitable for running?

Choose lightweight polyester shorts or mesh shorts with plenty of room for movement. Look for an adjustable waistband, a suitable length and pockets that do not hang loosely. Cotton shorts may feel comfortable during your warm-up, but are less practical when you sweat heavily or need the shorts to dry quickly.

How do I choose the right size of men’s shorts?

Measure your waist where the waistband normally sits, then check the brand’s size chart. Also look at hip measurement, inside-leg length and fit. With a loose fit, there should be more room around the legs; with a regular fit, the shorts should sit more evenly against the body. If you are between sizes, pay particular attention to the stated waistband measurement and whether the shorts have a drawstring.

How long do shorts typically last?

This depends on how they are used, how often they are washed, friction and drying. Shorts worn every day may wear out faster if they are washed frequently than a pair worn occasionally. Wash them according to the label, use the recommended temperature and regularly check the seams, waistband and pockets. With swim shorts, rinsing them after use in chlorinated or salt water helps prevent residue from remaining unnecessarily in the fabric.
