Choosing men’s T-shirts and sweatshirts: a practical guide to fit, fabric and use

Ordering a new item of clothing online seems simple, until the fabric turns out to be thinner than expected, the sizing is different or a sweatshirt loses its shape after a few washes. When choosing men’s T-shirts and sweatshirts, it’s about more than just the brand or colour. Fit, fabric, care and how you plan to wear it all affect whether a garment is right for everyday wear, travel, sport or layering.

Common pitfalls when choosing men’s T-shirts and sweatshirts

1. Relying on the size letter alone

A size L isn’t the same across every brand. A men’s slim-fit T-shirt may be narrower across the chest and waist, while a regular-fit sweatshirt offers more room to move. You should also check descriptions such as “comes up large” or “true to size” against the size guide.

Pay particular attention to:

  • Chest and waist measurements in centimetres.
  • The length of the T-shirt or sweatshirt.
  • Shoulder width and sleeve length.
  • Whether you want a close-fitting or looser fit.

2. Mistaking marketing claims for measurable features

Words such as “breathable”, “performance” and “moisture-wicking” don’t mean much on their own. Check the fabric and see whether the product information explains which construction or fibres deliver these features. According to some brands’ product information, polyester or cotton blends can help move moisture from the skin to the outside of the fabric. This is a brand claim, not a guarantee that everyone will have the same experience.

“Antibacterial” is another claim to look into carefully. According to the product information, PELLIOT uses POLYGIENE technology to inhibit odour-causing bacteria. Treat this as a technical product feature, not a medical or hygiene guarantee.

3. Underestimating garment care

A cotton T-shirt can feel comfortable, but it may shrink or lose its shape if you wash it at too high a temperature or tumble-dry it. Polyester can be practical for sport, but it may need different care. Always check the care label and follow the instructions on the product page.

Three key things to check before you buy

Fabric: cotton, polyester or a blend

A men’s cotton T-shirt is often a comfortable choice for everyday wear and casual menswear. Cotton feels soft and lets air circulate, but it usually takes longer to dry than polyester.

A polyester or cotton-polyester blend can be a good option for sport, travel and more intensive use. Blends often combine a softer feel with better shape retention. Check the exact percentages:

  • 100% cotton: soft and versatile for everyday wear.
  • Cotton with elastane: more stretch and freedom of movement.
  • Cotton with polyester: a practical blend for everyday wear.
  • Polyester piqué: a good choice when quick drying and moisture wicking matter.

Fit and neckline

A men’s crew-neck T-shirt is easy to wear with jeans, shorts, joggers or a jacket. A men’s slim-fit T-shirt sits closer to the chest and waist. It can look smart, but may feel less comfortable if you’re between sizes or need extra room to move.

On a sweatshirt, a ribbed neckline, cuffs and hem are useful details. They help keep the garment in place. A men’s fleece sweatshirt is usually warmer than a lightweight cotton sweatshirt, but can feel too warm indoors.

Sizing in practice

Use the size guide for the specific product, especially if you’re looking for men’s clothing in size L. For example, the Under Armour Rival Fleece is described as coming up large, so you may want to size down. For the Tommy Hilfiger Core Stretch Slim C-Neck Tee, the chest measurement for size L is 103–108 cm. The Calvin Klein Core Monologo Pocket Slim Tee, on the other hand, is also described as coming up large.

If possible, measure a T-shirt you find comfortable and compare its chest measurement with the size guide. Choose a roomier size if you’re between sizes or want to wear the garment over a base layer.

Frequently asked questions about men’s T-shirts and sweatshirts

How do I find the right size men’s T-shirt?

Measure your chest at its widest point and compare it with the product’s size guide. Also check whether the style is slim fit, regular fit or oversized. If you’re between sizes, the larger size is often more practical for layering or extra room to move, but always follow the specific product information.

Which fabric is suitable for sport and travel?

For sport and travel, polyester or a cotton-polyester blend can be useful because it absorbs less moisture and usually dries faster. Check that the product description specifically mentions moisture wicking or quick-drying properties. For everyday wear, a men’s cotton T-shirt remains a versatile choice.

How can I stop a sweatshirt from losing its shape quickly?

Wash your sweatshirt according to the care label, don’t use bleach unless the label says it’s suitable, and avoid high drying temperatures. Turn printed styles inside out and don’t iron directly over the print. A sweatshirt with a ribbed neckline, cuffs and hem can also help the garment stay in place while you wear it.
