How to choose sportswear without regret: practical tips and popular picks

The right sportswear should suit your activity, body and laundry routine. Yet it’s easy to pay too much for a logo, or choose a T-shirt that feels comfortable at the gym but gets too warm when you’re running. Men’s and women’s sportswear also differ in more than colour or fit: sizing, fabric and freedom of movement all affect how much you’ll get out of your clothes.

In this guide, you’ll find out what to look for in sports tops, sports trousers, jogging bottoms, training trousers and running tops. Then you’ll find a selection of products for different needs.

Three common sportswear pitfalls

1. Confusing a sporty look with technical features

A striking logo or modern cut says little about comfort. A cotton T-shirt can feel soft and light, but that doesn’t automatically make it suitable for intense workouts. So always check the fabric composition and the features listed.

2. Choosing the wrong fit

An overly loose top can get in the way during fitness sessions or yoga. A very tight style, on the other hand, can restrict your movement. Look for terms such as regular fit, slim fit and fitted. Check the size guide too, and measure your chest, waist or hips rather than relying only on the size you usually wear.

3. Ignoring care instructions

Sportswear is often washed frequently and sometimes tumble-dried on a low setting. Trousers that need a delicate wash require more attention than everyday clothing. Care instructions can also tell you about colour retention, shrinkage and fabric lifespan. Don’t use fabric softener if the product information advises against it.

Which specifications matter?

Fabric: cotton, polyester or a blend

Cotton feels soft and is suitable for everyday wear, warm-ups and comfortable leisurewear. For example, the Nike Sportswear Club T-shirts are made from 100% cotton and have a classic, relaxed fit, according to the product description.

Polyester is lightweight and often used in fitness clothing, running tops and training trousers. The product description for the K-Swiss Kswiss Hypercourt Print Crew 5 mentions a lightweight polyester fabric with breathable, moisture-managing properties. This makes it particularly appealing for tennis and active training.

A cotton-polyester blend can combine softness with shape retention. According to the product specifications, the Adidas Trefoil Essentials Pants are made from 70% cotton and 30% recycled polyester fleece.

Please note: features such as moisture wicking, odour control or quick drying are claims made by the product or brand. Use them to compare styles, rather than assuming every garment will feel the same for every wearer.

Fit and freedom of movement

Choose a style to suit your activity:

  • Regular fit: suitable for everyday wear, warm-ups and relaxed workouts.
  • Slim fit: closer to the body and suited to a streamlined casual look.
  • Fitted: sits close to the body and can be comfortable for running, provided you choose the right size.
  • Racerback or sleeveless: some women’s sportswear styles offer extra room around the shoulders.

An elasticated waistband with a drawstring is practical for jogging bottoms and training trousers. You can adjust the fit as needed, for example when wearing the trousers for a warm-up or at home.

Pockets and hems

Side pockets are handy for keys or a phone when you’re out and about. The Under Armour Men's Tricot Jogger is listed as having open hand pockets, a back pocket and an internal phone pocket. If you want to keep valuables in a pocket while running, always check its size and fastening.

Ribbed cuffs help keep trouser legs in place. An overlapping hem or ventilation detail may improve airflow, according to the product description, but the effect depends on your activity, the temperature and your personal preference.

Frequently asked questions about sportswear

What sportswear is suitable for fitness?

Choose a T-shirt or top that gives you enough room to move and doesn’t feel tight around your shoulders or underarms. Lightweight synthetic fabrics are often practical for intense fitness sessions; cotton can be more comfortable for gentle exercise or warm-ups. Pair a sports top with training trousers that have an adjustable waist.

How often should you replace sportswear?

It depends on how often you wear it, the fabric and how you care for it. Replace a garment when the seams come undone, the waistband loses its shape, the fabric becomes thin or the fit changes permanently. Follow the washing instructions and wash sportswear after intense use, as directed on the care label.

What’s the difference between jogging bottoms and training trousers?

Jogging bottoms are usually designed for comfort and everyday wear, often in a softer fleece or terry fabric. Training trousers are generally lighter and designed more for movement, warm-ups or sports activities. The product specifications, fit and fabric matter more than the name alone.
