How to choose sportswear without a costly mistake: find the right fit and fabric

Sportswear needs to do more than look the part. Leggings that slide down, a sports top that restricts your movement or a T-shirt that loses its shape after a few washes won’t give you much value for money. Yet many product pages focus on terms such as “quick dry”, “high performance” and “premium comfort” without making the practical details clear.

This guide helps you compare sportswear using details you can check. It’ll make it easier to find women’s sportswear, men’s sportswear, yoga wear, gym wear, running clothes or casual wear to suit the way you’ll use it.

Three common sportswear pitfalls

1. A sporty name doesn’t tell you much about the fabric

“Quick-drying clothes” and “breathable clothing” are useful search terms, but always check the fabric composition. Polyester can be lightweight and practical for intense exercise, while cotton often feels comfortable for everyday wear. A product from a big-name brand isn’t automatically suitable for running or gym workouts.

Look out for conflicting information, too. Some listings have a general product description that doesn’t match the specifications table. If that’s the case, use the current size guide and product details as your starting point.

2. Fit is often underestimated

A slim-fit T-shirt, high-waisted sports leggings and a loose-fit sports top won’t fit in the same way. So don’t just look at S, M, L or XL; check measurements such as chest, waist and garment length, too.

For sports trousers and joggers, an adjustable waistband, drawstring and cuffs are practical details. With sports leggings, the waist height, leg length and stretch are particularly important for your freedom of movement.

3. Care affects how long your clothes last

A garment might seem suitable for everyday wear, but washing it incorrectly can make it wear out sooner. Before buying, check:

  • the maximum washing temperature;
  • whether it can be tumble-dried;
  • whether it needs to be turned inside out for washing;
  • whether prints and logos need special care;
  • whether dark colours need to be washed separately.

For several Adidas and Lee products, washing at a low temperature and avoiding the tumble dryer are recommended. This is worth bearing in mind if you wash sportswear frequently.

Which specifications should you check?

Fabric: choose according to your activity

For running clothes, football shirts and intense gym workouts, lightweight synthetic fabrics are often practical. The Nike Dri-FIT Park 20 Tee is described as featuring moisture-managing Dri-FIT technology and a lightweight fabric. However, the product specifications state a composition of 57% cotton and 43% polyester, while the general description says 100% polyester. Check the final details on the product page before ordering.

For yoga wear, walking and everyday use, a soft, stretchy fabric may matter more than maximum moisture management. According to its listing, the Adidas Adicolor Classics 3-Stripes Tee is made from 100% cotton and has a slim fit. This makes it particularly appealing as a casual T-shirt, for example with jeans or joggers.

Fit and measurements

Look out for terms such as:

  • high waist: a higher waistband, often chosen for yoga wear and sports leggings;
  • regular fit: a more traditional fit;
  • slim fit: sits closer to the body;
  • loose fit: generally gives you more room around the body;
  • 7/8 or capri: a shorter leg length than full-length sports leggings.

The Skechers Go Walk High Waisted 7/8 Legging is listed as black women’s leggings made from nylon with elastane and a regular fit. They’re shorter than full-length leggings, which can be practical for everyday wear or working out in a warmer space.

Support and freedom of movement

A sports bra or crop top should suit the intensity of your activity. According to the product information, the Lee Bra Crop Tops offer light support and are intended for activities such as yoga, walking, stretching or relaxed wear. For intense running, it’s a good idea to look specifically for a style with a clearly stated support level.

Men’s sportswear also includes underwear worth considering. The Reebok Sports Brief Wiggins is sold as a 3-pack with an elasticated waistband. Check the exact fabric composition and care instructions if breathable fabric and shape retention are particularly important to you.

Frequently asked questions about sportswear

What sportswear do I need for the gym?

A sports top or T-shirt, sports leggings or trousers, and suitable trainers are a practical starting point for the gym. Choose a fit that won’t restrict your movement during squats, lunges and strength training. Also check that the waistband stays in place and that, according to the product information, the fabric is suitable for moisture management.

How often should I wash sportswear?

Wash sportswear after intensive use, following the care label. Use the recommended temperature where possible, and avoid the tumble dryer if the label advises against it. Sports bras, sports tops and leggings generally keep their shape better if you don’t wash them at too high a temperature and wash similar colours together.

What’s the difference between sportswear and casual wear?

Sportswear is usually designed with freedom of movement, a specific fit or fabric for exercise in mind. Casual wear, such as a cotton T-shirt or fleece joggers, is primarily made for everyday comfort. Some styles combine both functions, but always check the fabric, fit and care instructions before wearing them for intense exercise.
