When choosing a tracksuit, read its fabric composition, sizing and intended use as well as considering its appearance. Tracksuits from the same brand may use different fabrics and fits.
Quick answer
The KX red-and-black half-zip training tracksuit description lists 40% polyester, 40% cotton and 20% Lycra. Do not choose a size using height and weight alone: consider garment measurements, a movement test and the care label together.
Which model does this guide cover?
The specific fabric information here applies to the linked KX Logo Stretch Half-Zip Training Tracksuit in red and black. The description specifies a half zip and stretch construction. Read the description separately when buying another colour or range.
How to read fabric composition
The product page states 40% polyester, 40% cotton and 20% Lycra. This composition alone does not guarantee identical comfort in every season, no sweating or no fading after washing. Do not apply the term “three-thread fabric” to every tracksuit: knit construction and fibre percentages describe different things. If the label and page differ, ask the seller to confirm.
Sizing and movement checks
- Find the current size chart or garment measurements.
- Try the top and trousers with the layer you intend to wear underneath.
- Reach out, squat and bend your knees.
- Check for excessive pulling at the waist, crotch, knees and arms.
- Open and close the zip, checking the fit around your neck and chest.
The model’s height, weight and size on a product page are only a reference; they do not determine the same size for everyone. Do not automatically size down for a closer-fitting appearance.
Training and everyday use
Warming up, waiting beside the pitch and everyday wear involve different movement and temperature conditions. Choose layers around training intensity and the weather. Check photographs and descriptions for details such as pockets or hoods rather than assuming every model has them.
Use the care label
Base washing temperature, drying and ironing decisions on the garment’s label. Follow any additional instructions for printed surfaces or zips. One washing temperature or tumble-drying rule cannot be applied to every tracksuit.
