Buying sportswear online: how to choose comfortable, functional clothing

Anyone searching for sportswear online will quickly find hundreds of results, from sweatshirts and hoodies to waterproof jackets, joggers and clothing from well-known brands. However, an appealing product photo tells you little about the fit, material or suitability for the Dutch weather. The right choice mainly depends on how you plan to use the item and on the product specifications you can verify.

Common pitfalls when buying clothes online

1. Mistaking a marketing term for a technical specification

Words such as “all-weather”, “breathable” or “durable” sound clear, but are difficult to assess without further information. So check:

  • the material and composition;
  • whether the seams are sealed;
  • which fastenings and pockets are included;
  • whether a hydrostatic head rating, membrane or other technical specification is mentioned.

For example, DryVent is mentioned for several jackets in this selection. This is a brand name for a material system. Its performance should be read as product information provided by the brand, not as a universal guarantee for every weather condition.

2. Relying only on your usual size

Sizes vary by brand, collection and model. A men’s jacket in size M may fit differently from a sweatshirt in size M. Always check the size guide and compare your chest, waist and hip measurements with a garment that already fits you well.

Also consider the layer you want to wear underneath. An extra mid-layer can be useful under a waterproof jacket. For example, the PELLIOT jacket lists a chest measurement of 116 cm in size M. If you want to wear a thick sweatshirt underneath, the product information suggests considering one size larger.

3. Assuming a soft fabric is automatically suitable for training

A fleece sweatshirt or fluffy pair of joggers can be comfortable for relaxing at home, travelling and casual wear. That does not automatically mean the material is suitable for intensive training. For sportswear, factors such as moisture wicking, drying time, freedom of movement and the finish at the waist or legs are all relevant.

A cotton blend often feels comfortable, while polyester is regularly chosen for sportswear because it is lightweight and dries more quickly. So assess the composition in relation to how you intend to use the garment.

Important specifications to check

Material and care

The fibre composition affects how a garment feels, how warm it is and how it should be cared for. Here are some examples from the selection:

  • The adidas Trefoil Essentials Crew Sweatshirt is made from 70% cotton and 30% recycled polyester.
  • The Urban Classics Fluffy Sweatpants are made from 70% cotton and 30% polyester.
  • According to the product information, the Under Armour Tricot Jogger is made from 100% polyester.
  • The women’s jacket from The North Face has a 100% polyester outer layer and a mesh lining.

Also check the washing instructions. Some garments must not be tumble-dried or require a low temperature. With technical jackets, do not use fabric softener if the care label advises against it, as this may affect the fabric’s performance.

Fit and freedom of movement

Choose a fit that suits the situation:

  • Regular fit: practical for everyday wear and light training.
  • Relaxed fit: suitable for layering and relaxed streetwear.
  • Tapered fit: narrower towards the ankle, as with modern joggers.
  • Utility fit: often designed to provide freedom of movement and functional details.

As well as the size, check the length of the sleeves and trouser legs. For example, the Under Armour jogger lists an inside leg length of 76 cm for size M. This is more useful than simply stating “true to size”.

Protection from rain and wind

A waterproof jacket is not automatically the same as a jacket for long mountain treks. Check whether the description mentions waterproof fabric, wind protection, taped seams, an adjustable hood and ventilation.

According to the product information, the PELLIOT Waterproof Jacket features a waterproof laminate layer, a wind-resistant construction and hard-wearing fabric. The North Face jackets are described in the brand and product information as having a fully sealed DryVent construction with a DWR finish. Actual suitability also depends on care, activity level and weather conditions.

Smart combinations for everyday wear

A practical wardrobe does not have to be large. For example, pair a hoodie or sweatshirt with joggers for leisure time and travelling. A Reebok T-shirt made from 60% cotton and 40% polyester works well under a gilet or jacket. For men, you can pair an Under Armour jogger with a sweatshirt and trainers; women’s clothing such as a blouson or trench coat works well over sporty basics.

When choosing sustainable clothing, look for concrete information such as recycled polyester or a stated material percentage. A sustainability claim without a composition, certification or explanation offers less to go on. According to the product information, the PELLIOT jacket contains recycled material in the outer fabric, while the adidas sweatshirt is made from 30% recycled polyester.

Frequently asked questions about sportswear online

Which sportswear is suitable for Dutch weather?

Choose layers: a breathable T-shirt or sweatshirt as a base layer and a water- and wind-resistant jacket as the outer layer. Check that the jacket has sealed seams, an adjustable hood and suitable care instructions.

How do I choose the right clothing size online?

Measure your chest, waist, hips and, if necessary, inside leg. Compare these measurements with the table on the product page. When choosing jackets, allow extra room for a hoodie or fleece mid-layer.

How can I keep sportswear looking good for longer?

Follow the care label, wash dark colours separately and do not use fabric softener for garments where it is not recommended. Dry technical jackets according to the instructions and only reapply a water-repellent finish when the care advice indicates that this is necessary.
