Choosing an Under Armour men’s Sportstyle T-shirt: a practical buying guide for sport and everyday wear

A men’s T-shirt in the UK often needs to serve several purposes: comfortable for the gym, suitable for training and smart enough for a casual outfit. The Under Armour men’s Sportstyle T-shirt is a popular choice, but product names and marketing claims don’t always tell the whole story. So pay close attention to the material, fit, sizing and care instructions.

Common pitfalls when choosing a sports T-shirt

1. Assuming “quick-drying” means fully technical sportswear

A men’s cotton T-shirt feels soft, but cotton can hold on to moisture for longer than polyester. A cotton blend can therefore be a practical compromise: comfortable for everyday wear and, according to the product description, designed to dry quickly and wick away moisture. However, for intense training, don’t automatically expect it to feel as light as a shirt made entirely from synthetic fibres.

The stated fabric composition of the Under Armour Sportstyle Collection is 60% cotton and 40% polyester. The product description says that the material wicks sweat away and dries quickly. This information comes from the product description; your experience may vary depending on the activity and the person.

2. Choosing by letter size alone

A size M isn’t the same across every brand or style. When choosing an Under Armour men’s T-shirt, check your chest measurement rather than relying only on S, M, L or XL. The Sportstyle styles have a regular fit: a classic cut that’s neither tight nor loose.

The stated chest measurements are as follows:

  • XS: 79–86 cm
  • S: 86–94 cm
  • M: 94–104 cm
  • L: 104–112 cm
  • XL: 112–122 cm
  • XXL: 122–132 cm

If you’re unsure, measure a T-shirt that fits you comfortably and compare the measurements. If you’re between sizes, consider whether you’ll mainly wear the shirt for sport or casually.

3. Overlooking care instructions

A men’s sports T-shirt can lose its shape or colour more quickly if washed at too high a temperature or treated with fabric softener. According to the product information for these Under Armour styles, it’s best to:

  • wash the shirt inside out;
  • wash it in cold water with similar colours;
  • use only non-chlorine bleach when needed;
  • tumble dry on a low heat;
  • do not iron;
  • do not use fabric softener or dryer sheets.

Always follow the care label on the specific item. This helps reduce shrinkage, fading and unnecessary wear.

What should you look for when buying?

Material: comfort versus moisture management

The combination of 60% cotton and 40% polyester makes these Sportstyle styles a good option if you’re looking for one shirt to wear in different situations. Cotton feels soft against the skin, while polyester helps reduce moisture retention and supports quicker drying, according to the product description.

This kind of blend is practical for gentle gym sessions, weight training, walking and everyday wear. For very intense cardio or prolonged outdoor exercise, a lighter, more technical fabric may be a better choice. A moisture-wicking T-shirt doesn’t guarantee that you’ll stay dry; sweating, ventilation and the intensity of your activity all play a part.

Fit and sleeves

The short sleeves allow you to move freely during training and are easy to pair with sportswear or jeans. A men’s regular-fit T-shirt generally offers more room around the body than a slim-fit style. Pay particular attention to the chest measurement if you have broad shoulders or prefer a looser fit.

For layering or cooler days, a long-sleeved style from the same collection is an alternative. You can wear it under a cardigan or a training jacket.

Colour and use

A black Under Armour T-shirt is less likely to show dark stains and goes with almost any pair of sports trousers. A white Under Armour T-shirt has a lighter look, but needs more care when it comes to washing and stains. Grey is a middle ground and works well for both sport and casual wear.

Your choice of colour doesn’t affect the size or fabric composition. Always check the individual product page, as colours, sizes and stock are listed separately for each item.
