Choosing an Under Armour Sportstyle T-shirt: a practical guide for training and everyday wear

An Under Armour Sportstyle T-shirt can be suitable for the gym, a training session or a casual outfit. However, a well-known brand name does not automatically mean that every model will suit your needs. With an Under Armour sports T-shirt in particular, features such as “quick-drying” and “breathable” are often mentioned casually, while differences in fabric, fit and sizing determine how comfortable it is to wear.

Look out for these common pitfalls before ordering:

  • Confusing cotton and polyester: a cotton sports T-shirt feels soft, but generally dries differently from a fully polyester T-shirt.
  • Relying solely on the letter size: an M can represent a different chest or waist measurement in women’s and men’s models.
  • Treating marketing claims as guarantees: terms such as moisture-wicking, odour control and breathable describe product features, but do not say exactly how the T-shirt will feel in every training situation.

What should you look for in a short-sleeved Under Armour T-shirt?

1. Fabric: cotton blend or polyester

The short-sleeved Under Armour T-shirts in this selection are mainly made from two types of material:

  • 60% cotton and 40% polyester: a cotton blend which, according to the product description, feels soft and is suitable for everyday wear, workouts and training.
  • 100% polyester: a lightweight material which, according to the product description, dries quickly and wicks sweat away from the skin. This type is particularly suitable for more intensive training or when you are looking for a quick-drying T-shirt.

A cotton blend is a sensible choice if you want to wear one T-shirt while exercising and afterwards in your free time. If you are mainly looking for a lightweight, breathable T-shirt for active sessions, polyester may be more practical. Under Armour’s product information describes these features; they should not be interpreted as medical properties or guaranteed performance.

2. Fit and freedom of movement

A regular-fit T-shirt sits between a close and a loose fit. This makes it useful for fitness, strength training and casual outfits. Always check the size guide:

  • Women’s model S: EU 34-36, chest measurement 85-91.5 cm for the cotton-blend model.
  • Women’s model M: EU 36-38, chest measurement 91.5-96.5 cm for the cotton-blend model.
  • Men’s model S: EU 46-48, chest measurement 86-94 cm.
  • Men’s model L: EU 50-52, chest measurement 104-112 cm.
  • Men’s model XXL: EU 54, chest measurement 122-132 cm.

The sizes shown are specific to each product. You therefore cannot compare a women’s Under Armour T-shirt and a men’s Under Armour T-shirt directly based on S, M or L alone. If in doubt, measure your chest and then check the table on the product page.

3. Washing instructions and longevity

The selected T-shirts have similar care instructions:

  • Turn the T-shirt inside out.
  • Use a cold machine cycle and wash with similar colours.
  • Use only non-chlorine bleach when necessary.
  • Tumble dry on a low setting.
  • Do not iron, dry-clean or use fabric softener.

These instructions help keep the colour, collar and fabric in good condition for longer. A black version may also show colour transfer if it is frequently washed with light-coloured laundry. For a white sports T-shirt, washing it with similar light colours is advisable.

Black, white or grey: which colour suits your needs?

A black-and-white sports T-shirt is easy to pair with jogging bottoms or shorts. Black hides light marks better while you are exercising, but may lose its colour more quickly if it is not cared for correctly. A white sports T-shirt looks fresh and works well with casual clothing, but requires more care when sorting your laundry. Grey is a practical middle ground for anyone who prefers less contrast.

Also pay attention to the differences between product variants. Some women’s models have a crew neck, while the UA Tech version has a V-neck. Men’s models are available in black, grey and white/black. Before checking out, compare the product title, image, size and fabric composition together.

Frequently asked questions about an Under Armour Sportstyle T-shirt

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

Yes, according to the product descriptions, the models mentioned are intended for workouts, training and everyday use. Choose a cotton blend for a soft, versatile T-shirt, or 100% polyester if quick drying is more important to you.

How do I choose the right size?

Measure your chest at the fullest point and compare it with the table on the specific product page. A regular fit should not sit tightly against the body. So do not automatically choose the same letter size as you would for another brand or a model designed for a different gender.

How can I prevent the T-shirt from wearing out quickly?

Wash the T-shirt inside out on a cold cycle, use similar colours and dry it at a low temperature. Avoid fabric softener and ironing. These care instructions are listed for the selected Under Armour training T-shirts and help preserve the fabric and shape.
