Choosing an Under Armour men’s Sportstyle T-shirt: fit, fabric and use explained

An Under Armour men’s Sportstyle T-shirt might seem easy to choose at first. However, small differences in colour, fit, fabric and size can determine whether you wear it mainly for fitness or also as an everyday T-shirt. For example, a black men’s T-shirt that feels comfortable at the gym should also keep its shape after several washes.

As a Joybuy Product Recommendation Officer, I filter product information for practical details. This helps you quickly see which features you can verify and which marketing terms are best treated with a degree of caution.

Common pitfalls when choosing a men’s sports T-shirt

1. “Breathable” doesn’t automatically mean it feels cool

A breathable men’s T-shirt can feel comfortable during light training, walks or everyday wear. However, the term doesn’t specify exactly how much air the fabric lets through. The selected Sportstyle models are made from 60% cotton and 40% polyester. This blend combines a soft feel with synthetic fibres that, according to the product description, help the fabric dry faster.

So, if you’re looking for a pure cotton men’s sports T-shirt, check the fabric composition carefully. Cotton feels comfortable, but it generally takes longer to dry than polyester.

2. Moisture management doesn’t guarantee you’ll stay dry

The product information for several models mentions fast-drying, moisture-wicking and sweat management. These are Under Armour product claims. According to Under Armour’s product description, the fabric is designed to wick away moisture and dry faster. Your experience may vary depending on the intensity of your training, the temperature, ventilation and personal preference.

So don’t just look at the claim: check the full fabric composition, weight and fit too. A looser T-shirt feels different from a close-fitting one, even if both list the same technology.

3. The wrong size can make a regular fit uncomfortable

A regular-fit men’s T-shirt shouldn’t feel tight or hang excessively loose. However, the fit can vary between models or colour options. Check your chest measurement in centimetres rather than relying on S, L or XL alone.

The Sportstyle models in this selection are available in sizes ranging from S to XL, among others. Always check the size guide on the product page before ordering.

Which features should you check?

Fabric: a cotton and polyester blend

The selected Under Armour Sportstyle T-shirts are made from a blend of 60% cotton and 40% polyester. In practice, this means:

  • cotton contributes to a soft, familiar feel;
  • polyester can help the fabric dry faster;
  • the blend is suitable for training and casual wear;
  • the T-shirt isn’t the same as a pure cotton style.

For some colour options, the product information also states that the main fabric contains at least 40% recycled polyester, excluding trims and decorations. Check each option, as the information may not be identical for every product.

Fit and chest measurement

The Sportstyle Collection is described as regular fit. Use these measurements as a guide:

  • S: chest measurement approximately 86–94 cm;
  • M: chest measurement approximately 94–104 cm;
  • L: chest measurement approximately 104–112 cm;
  • XL: chest measurement approximately 112–122 cm.

The size guide may vary between versions. For example, some sizes in a black and white option use a slightly different guide from the all-black version. If you’re unsure, measure a T-shirt you find comfortable and compare the chest width and overall length in particular.

Care and lifespan

For most models, the product information recommends:

  • washing inside out;
  • washing cold with similar colours;
  • using only non-chlorine bleach when needed;
  • tumble-drying on a low setting;
  • not ironing;
  • not using fabric softener;
  • not dry-cleaning.

Following these instructions can help the colour, collar and fit last longer. And just because a T-shirt is quick-drying doesn’t mean you need to tumble-dry it on a high setting; a low setting or air-drying is more practical for regular wear.

Frequently asked questions about Under Armour Sportstyle T-shirts

Is an Under Armour Sportstyle T-shirt suitable for fitness?

According to the product description, these T-shirts are designed for workouts, training and everyday wear. Their regular fit, short sleeves and cotton and polyester blend make them suitable for general fitness and light to moderate sporting activities. For intense outdoor sports, a fully technical T-shirt with a different fit may better suit your preferences.

How do I choose between sizes S, L and XL?

Measure your chest at its widest point and compare it with the size guide for your chosen colour option. As a guide, S is approximately 86–94 cm, L is 104–112 cm and XL is 112–122 cm. Always check the specific product page before buying, as size guides can vary between versions.

How should you wash a moisture-wicking T-shirt?

Wash the T-shirt inside out in cold water with similar colours. Don’t use fabric softener and tumble-dry on a low setting. If in doubt, follow the care label in the garment. This helps limit unnecessary wear to the fabric and the shape of the ribbed collar.
