Choosing men's sports shorts: consider fabric, fit and pockets

A pair of men's sports shorts may seem easy to choose, but small differences can determine whether you mainly wear them for training, lounging on the sofa or as part of a casual outfit. Fabric that’s too warm can be uncomfortable during intense exercise, while lightweight shorts may feel less comfortable for everyday wear.

Marketing terms can also be confusing. That’s why the Joybuy Product Recommendation Officer focuses on things you can check: fabric composition, waistband, length, pockets and the size chart.

Common pitfalls when choosing men's shorts

1. Focusing only on the brand or colour

A well-known name doesn’t tell you anything about the fit or fabric. PUMA men's shorts and Under Armour men's shorts, for example, are available in a range of fabrics and styles. So always check whether you’re buying fleece, French Terry or woven shorts.

2. An elasticated waistband without a good fit

An elasticated waistband allows you to move freely, but not every style stays in place equally well. An internal or external drawcord lets you adjust the waist. This is particularly useful for fitness, warm-ups and sports that involve lots of movement.

3. Assuming “breathable” means suitable for every workout

Cotton shorts can feel soft and comfortable, but they generally hold on to more moisture than a lightweight polyester style. Polyester, on the other hand, can be useful for training but may feel less cosy when you’re relaxing. So think about when you’re most likely to wear them.

Which features should you check?

Fabric: cotton, fleece, French Terry or polyester

  • Cotton blend: a combination such as 80% cotton and 20% polyester generally feels soft and is suitable for everyday wear, warm-ups and relaxing.
  • Fleece: a brushed interior is described in the product details as providing extra warmth. This makes it suitable for cooler days, but less suited to intense summer workouts.
  • French Terry: according to the product information, this fabric has a smooth outer surface and a softer inside. It’s a versatile middle ground for training, travel and casual wear.
  • Woven polyester: lightweight and often suitable for sports where freedom of movement and quick drying are important. According to PUMA's product information, this particular style features dryCELL technology. Its moisture-wicking performance is a claim made by the brand, not a general guarantee for every wearer.

If you’re specifically looking for men's cotton shorts or men's fleece shorts, it’s worth comparing the fibre composition rather than relying on the product title alone.

Fit and length

A regular fit gives you room to move without being excessively loose. A loose fit offers more freedom of movement, but may feel less streamlined during exercise. Also check the inside leg measurement:

  • Around 6 inches, or 15 cm, gives a relatively short length and a sporty look.
  • A knee-length style offers more coverage and works well with casual outfits.
  • A style that sits above the knee is a practical mid-length option for training and everyday wear.

To find your size, measure your natural waist. For the Under Armour Rival Fleece Shorts, size L corresponds to a waist measurement of 86 to 94 cm and size XL to 94 to 104 cm, according to the size chart. The styles have a regular fit and an inside leg measurement of 25 cm.

Pockets and waistband

Check whether the shorts have pockets and whether they’re open or fasten securely. An open side pocket is handy for keys or a phone on a walk. A popper-fastening back pocket offers extra security, but isn’t included on every style.

Shorts with an elasticated waistband and drawcord are usually more versatile than styles without an adjustable fastening. Also check the care instructions. Some styles can be tumble-dried at a low temperature, while others should only be air-dried.

Frequently asked questions about men's sports shorts

Which men's sports shorts are suitable for the gym?

For the gym, an adjustable waistband, plenty of room to move and a suitable length are important. Choose a lightweight woven style for intense workouts, or French Terry if comfort during your warm-up and cool-down matters more.

Are men's cotton shorts suitable for sport?

They can be a good choice for light training, walking and weight training. Cotton feels soft, but can hold on to moisture for longer. For intense or extended exercise, a lightweight polyester style may be more practical.

How do I find the right size of men's shorts?

Measure your waist where the shorts normally sit, then compare the measurement with the product size chart. Also check the fit: a regular fit is less roomy than a loose fit. If you’re unsure, comparing your waist, hip and inside leg measurements is more reliable than choosing by letter size alone.
