Choosing sportswear without regret: a practical guide for training and everyday use

Comfortable sportswear needs to do more than look sporty. In the Netherlands, the same outfit is often used for fitness, warming up, cycling to the gym or a casual day at home. Yet many purchases disappoint because of an unsuitable fit, unclear material claims or clothing that is difficult to care for.

This guide helps you compare sports shirts, men's T-shirts, women's T-shirts, sports hoodies and fleece sweatshirts based on verifiable product information.

Three common sportswear pitfalls

1. Confusing a brand name with the right functionality

Nike sportswear and Under Armour clothing are popular choices, but a brand name does not automatically tell you whether a garment is suitable for your training. Look at the fibre composition, fit and construction. A cotton T-shirt can be comfortable for everyday use, while a polyester shirt is often chosen for more intensive training.

Technologies such as Nike Dri-FIT and Under Armour UA Tech are associated by the brands with moisture management. Phrase this carefully: according to Nike's product information, Dri-FIT is designed to draw moisture away from the skin; according to Under Armour, UA Tech is designed as a quick-drying fabric. These claims come from the brands' product information and are not a guarantee that every user will have the same experience.

2. Focusing only on size and ignoring the fit

A size L can fit differently from one model to another. A regular fit generally offers more room than an athletic fit. So check not only the letter size, but also the stated chest measurement, waist measurement and the seller's advice.

Some Under Armour fleece models are described as having a loose fit, with the option of considering one size smaller. Other models are described as true to size. This difference is important when buying sportswear online.

3. Skipping the care instructions

Moisture-managing clothing may perform differently if you use fabric softener, wash it at a high temperature or dry it with excessive heat. Several products in this range recommend washing at a low temperature, washing inside out and avoiding fabric softener.

So read the care label before ordering. Also check colour retention, drying instructions and whether the material can be ironed. This helps prevent unnecessary wear and disappointment after just a few washes.

Important specifications to compare

Material: cotton, polyester or a blend

Cotton feels soft and works well for casual sportswear and low-intensity activities. However, it can retain moisture for longer than technical synthetic fabrics.

Polyester is lightweight and is often used in breathable sportswear. The product information for several shirts associates polyester with quick-drying or moisture-managing properties. Always check the exact composition. The K-Swiss Hypercourt Basic Crew, for example, consists of 94% polyester and 6% elastane, which the product description says results in a lightweight, stretchy garment.

Cotton-polyester blends aim to combine comfort and durability. According to the product information, the Under Armour Sportstyle T-shirts consist of 60% cotton and 40% polyester. According to the specifications, the fleece models contain 78% or 80% cotton, supplemented with polyester.

Fit and freedom of movement

For strength training, fitness and team sports, you need sufficient freedom of movement around the shoulders and underarms. A shirt that is too tight can pull during certain exercises, while one that is too loose may shift as you move.

Look out for these terms:

  • Regular fit: a classic fit with room around the body.
  • Athletic fit: generally closer-fitting and designed for active movement.
  • Stretch fabric: elastane or a similar fibre can provide extra freedom of movement.
  • Ribbed cuffs and hems: found on items including hoodies and fleece sweatshirts for a close-fitting finish.

Warmth, layering and when you will wear it

A T-shirt is practical as a base layer. A long-sleeved top is suitable when you want extra coverage during warm-ups or outdoor activities. A hoodie or fleece sweatshirt works as an additional layer during training in a cooler sports hall, on the way to the gym or for everyday wear.

A kangaroo pocket, adjustable hood and ribbed cuffs are practical hoodie details. Also check the weight and thickness of the fabric. A heavy fleece may be warmer, but is less suitable if you wear several layers.

Frequently asked questions about sportswear

Which sportswear is suitable for fitness and training?

Choose a shirt with sufficient freedom of movement, lightweight fabric and a fit that does not feel restrictive around the shoulders and underarms. For intensive training, many users look for polyester or a cotton-polyester blend. For warm-ups or outdoor use, a long-sleeved top, hoodie or fleece sweatshirt may be more practical as an extra layer.

Is moisture-managing clothing the same as breathable sportswear?

No. Moisture-managing refers to the way a fabric removes moisture or allows it to dry, according to the product information. Breathable is generally used to describe air circulation through the material. Check the fibre composition, weight and precise brand description rather than relying on these terms alone.

How long does sportswear last?

Its lifespan depends on use, perspiration, washing frequency and care. Washing garments inside out, using low temperatures and avoiding fabric softener can help keep the fabric and printed designs in good condition for longer. According to the product information, the products mentioned are covered by a statutory guarantee of at least two years under EU consumer law; additional rights may apply under Dutch law.
