Choosing men’s T-shirts: a practical guide for everyday wear, sports and base layers

A good men’s T-shirt needs to do more than look neat in a product photo. It should feel comfortable, keep its shape after washing and suit the occasion you are wearing it for. Yet sometimes you are mainly paying for a logo, while the material, size and fit are less suited to how you plan to use it.

In this guide, the Joybuy Product Recommendation Officer helps you compare men’s T-shirts objectively. You will learn what to look for in a men’s cotton T-shirt, basic men’s T-shirt, men’s undershirt or sporty men’s T-shirt.

Common pitfalls when choosing men’s T-shirts

A Calvin Klein men’s T-shirt or GANT men’s T-shirt may look polished, but the brand does not automatically mean that the model will suit your body or how you plan to wear it. Always check the material composition, the fit and the available sizes. A well-known name cannot make up for the wrong size or fabric that is too warm.

2. Confusing “breathable” with suitable for sports

Cotton generally feels pleasant for everyday wear, but it absorbs moisture. For training, a cotton-polyester blend may be more practical when the product information mentions quick-drying or moisture-management properties. According to Under Armour’s own information, certain Sportstyle models are designed with a cotton blend and technology that helps wick away sweat. Treat this as a product claim by the brand, not a guarantee for every user.

3. Choosing a size based only on S, M or L

Size labels vary between brands and models. That is why you should check your chest measurement, waist and the stated EU or UK size. A regular fit is usually less close-fitting than a slim fit, but the exact cut can vary by manufacturer. Also check whether the product is a men’s crew-neck T-shirt, an undershirt or a model designed to be worn on its own.

Which features should you check?

Material: cotton or a cotton blend?

A 100% cotton men’s T-shirt often feels soft and familiar. According to the brands’ product information, the selected GANT and Calvin Klein models in this guide are listed as 100% cotton. This makes them suitable for everyday wear, under a shirt or as a layer beneath a jumper.

A cotton blend can be a good option for sport and physical activity. According to the product description, the Under Armour Sportstyle T-shirts consist of 60% cotton and 40% polyester. The information also mentions a lightweight, quick-drying fabric. Always check the care label and the current product page before buying, as the finish and details may vary between versions.

Fit and neckline

A regular fit generally provides room to move without the T-shirt feeling loose. A men’s crew-neck T-shirt is versatile: wear it under a shirt, beneath a cardigan or on its own with jeans. Pay particular attention to the neckline when choosing an undershirt. A neckline that is too high or wide may show beneath an open shirt.

Sleeve length and size range

A short-sleeved men’s T-shirt is suitable for warmer weather, casual outfits and many types of training. A long-sleeved men’s T-shirt offers extra coverage and can be worn as a layer beneath a jacket or sweatshirt. If you have a larger build, it is sensible to look specifically for men’s plus-size T-shirts and check the chest measurement rather than automatically choosing a larger size.

Care instructions are also important. Some Under Armour models require washing at a low temperature, washing inside out and avoiding fabric softener. The Calvin Klein underwear listed in the selected product information specifies washing at 30 °C. Always follow the label on the garment you receive.

Frequently asked questions about men’s T-shirts

How often should I wash a men’s T-shirt?

Wash a T-shirt when it is dirty or sweaty. Follow the care label and, preferably, use the recommended temperature. Washing inside out can help keep the colour and print looking their best for longer. For sports models, only use products that are permitted according to the product information.

Is cotton suitable as a men’s undershirt?

Yes, a men’s cotton T-shirt can feel comfortable as a layer beneath a shirt, jumper or cardigan. However, pay attention to the fabric weight and neckline. A lightweight crew-neck model is less noticeable beneath clothing than a heavy T-shirt with a wide neckline.

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

Measure your chest at the fullest point and compare it with the size guide on the product page. Also check the fit: a regular fit generally offers more room than a slim fit. For men’s plus-size T-shirts, the chest measurement is more important than the letter size alone.
