Choosing a new sports shirt might seem straightforward, but small differences in fabric, fit and care can make all the difference to how much use you get out of it. A shirt that feels great for football, for example, could be too warm for running. And joggers that are comfortable around the house aren't necessarily suitable for an intense workout.
The most common buying mistakes come down to three pitfalls:
For football, fitness and running, polyester, polyamide or blends with elastane are commonly used. Polyester is lightweight and features in many sports shirts and training clothes. Cotton feels soft but tends to hold onto moisture longer than synthetic fabrics. That can be nice for comfortable leisurewear, but less practical during an intense workout.
Pay attention to the fabric composition. A product made from 100% polyester has different properties to a sweatshirt made from 70% cotton and 30% recycled polyester. A product description might mention moisture-wicking technology. Treat such claims as information from the brand and also look at the specific composition and care instructions. According to Nike's own information, Dri-FIT is designed to draw moisture away from the skin; the product page also states the fabric and fit used.
A regular fit usually offers more room than a slim fit. With football shirts, sports tops and running shorts, you want freedom of movement when sprinting, bending and twisting. A style that's too loose can snag or shift; one that's too tight can become uncomfortable during longer sessions.
In particular, check:
The stated size isn't always enough. For instance, the adidas Trefoil Essentials Pants in size S is given with a waist range of 76–81 cm, while size XL has a range of 91–96 cm. Use those figures as a starting point and compare them with a pair of trousers you already find comfortable.
Check the care label before you buy. Sportswear that gets washed frequently needs to be easy to look after. Some items can't go in the tumble dryer or need to be washed inside out. With dark sweatshirts and clothing with logos, washing separately helps prevent colour fading and damage to prints.
Also check practical details:
Within the EU, consumers generally have a statutory conformity guarantee of at least two years. That doesn't mean normal wear and tear is automatically covered. So keep the product information and follow the care instructions.

We've put together a full, up-to-date list of products that fully meet these strict selection criteria and current European safety regulations.
Choose a lightweight sports top or a simple polyester tee with a regular fit. A style like that can work for football, fitness and everyday wear. For swimming, running and intensive training, specific clothing is usually more practical, because length, lining and freedom of movement vary from one sport to another.
Wash according to the label, don't use bleach if it's not recommended and turn clothing with prints or embroidery inside out. Also avoid unnecessarily high temperatures. Check before you buy whether the item is suitable for your usual washing routine.
Measure your chest, waist and, if needed, inside leg length with a flexible tape measure. Compare the result with the size guide on the product page. Also look at the fit: slim fit is closer-fitting, while regular fit usually offers more room. When in doubt, the specific centimetre measurement is more reliable than just your usual clothing size.
