Choosing men’s sports shorts: how to find the right fit, fabric and features

Choosing a new pair of men’s sports shorts seems simple, until you have to decide between cotton shorts, quick-drying shorts or men’s compression shorts. A style might look comfortable in photos, but feel too warm at the gym, ride up when you’re running or lose its shape after a few washes.

When buying men’s sports shorts, it’s worth looking beyond the brand or colour and paying attention to the features. Below, you’ll find the main pitfalls to avoid, practical checks to make and some popular options for different activities.

Common pitfalls when choosing men’s shorts

1. A comfortable fabric that isn’t right for your activity

Cotton feels soft and is comfortable for relaxing or everyday wear. However, during intense exercise, cotton generally retains more moisture than polyester. This can make cotton sports shorts feel heavier and less comfortable.

For fitness, running and intense training, quick-drying polyester shorts are often more practical. Always check the exact fabric composition, though. A marketing term such as ‘moisture-wicking’ doesn’t tell you much on its own about the proportions of cotton, polyester and elastane.

2. The wrong fit because of a vague size guide

Sizing varies between brands and styles. A size L from one brand may fit differently from a size L from another. So, check:

  • the waist measurement in centimetres;
  • the inside leg measurement;
  • the fit description, such as regular fit or compression fit;
  • whether there’s a drawstring;
  • the rise and leg length.

An elasticated waistband helps you adjust the fit, but it won’t make up for the wrong size. This is especially important with compression styles: a close fit is part of the design, but shouldn’t be confused with a regular pair of sports shorts.

3. Not paying enough attention to pockets and seams

Side pockets are useful for carrying a key or card every day. When running, though, loose items can bounce around. Check the position and depth of the pockets. Some men’s sports shorts have a small dedicated pocket, while others only have open side pockets.

Check the seams around the crotch and inner thighs, too. According to the product description, a gusset, or extra panel, can provide more room to move. For intense activity, flat or strategically placed seams are often more practical than bulky seams that can chafe.

Important specifications to compare

Fabric and moisture management

French Terry fabrics are worth considering for relaxed wear, walking and downtime. According to the product descriptions for the styles mentioned, this fabric has a soft texture and a relatively smooth outer surface. The composition is key:

  • 68% cotton and 32% polyester: soft and suitable for casual wear, warm-ups and light training;
  • 80% cotton and 20% polyester: a combination of comfort and practicality for everyday wear;
  • 100% polyester: generally lightweight and suitable for activities where moisture and drying time matter;
  • polyester with elastane: suitable for a close fit and freedom of movement.

If a brand mentions technology such as dryCELL or HeatGear, present it as a brand claim. According to PUMA’s product description, dryCELL is designed to draw moisture away from the body. Under Armour’s product description says HeatGear is designed as a lightweight, quick-drying fabric. Your experience may vary depending on the wearer, activity and conditions.

Length and freedom of movement

Knee-length men’s shorts offer more coverage and work well for casual wear, strength training and walking. A length above the knee may feel more comfortable for running or exercises involving lots of leg movement. According to the product information, the Under Armour Rival Terry 6In has an inside leg measurement of 15 cm, or 6 inches.

Consider the combination of length and fit, too. Loose, long shorts may move differently during squats or cycling than a close-fitting style. A regular fit can be comfortable for strength training, while a shorter or stretchier style may feel more practical for men’s running and fitness shorts.

Washing instructions

A garment’s lifespan depends not only on the fabric, but also on how you care for it. Check the care label before ordering. The product information provided includes the following advice:

  • wash with similar colours;
  • wash inside out;
  • do not use bleach;
  • choose a low-temperature or cold wash;
  • do not use fabric softener with certain Under Armour styles;
  • do not iron decorations;
  • only tumble dry if the care instructions allow it.

Frequently asked questions about men’s sports shorts

Which men’s sports shorts are suitable for running?

Choose a lightweight style with a secure waistband, plenty of freedom to move and fabric described as quick-drying in the product details. A side pocket or small internal pocket can be handy for a key. For long runs, it’s worth checking beforehand that the pocket fastens securely.

Are cotton sports shorts suitable for the gym?

Cotton sports shorts can be comfortable for strength training, warm-ups and low-intensity activities. For intense cardio, polyester styles often retain less moisture, according to the features listed in the product description. Focus on the fabric composition and choose a style to suit your training.

How do I find the right size?

Measure your waist at its natural point and compare it with the size guide for the specific style. Check the fit, too. Regular-fit shorts are roomier than men’s compression shorts. If you’re between sizes, follow the product’s sizing advice rather than relying only on your usual letter size.
