Choosing men's underwear: how to find a comfortable set for every day

Men's underwear may seem simple to buy, but small differences in material, fit and waistband can have a major impact on your comfort. A cheap set may therefore prove less cost-effective if the fabric quickly loses its shape, the legs ride up or the waistband digs in.

This buying guide helps you compare men's boxer shorts, men's briefs and underwear multipacks objectively. The selection below is based on verifiable product information, such as material composition, fit, care instructions and number of items.

Common pitfalls when buying men's underwear

1. Looking only at the price per pack

A 3-pack of boxer shorts may seem attractively priced, but check the composition and size chart first. A three-piece multipack is not automatically better value if the fit does not suit your body or how you intend to use it. Therefore, consider both the price per item and the material.

2. Confusing “stretch” with a good fit

Stretch fabric allows freedom of movement, but does not tell you exactly how a pair of underwear will fit. A waistband that is too tight can still dig in, while a loose fit may shift around. Pay attention to the combination of elastane percentage, waistband and style. Trunks, briefs and longer boxer shorts each offer different levels of coverage and support.

3. Ignoring care instructions

Cotton boxer shorts can feel comfortable, but washing instructions vary from one product to another. Some styles must not be tumble-dried or may only be ironed at a low temperature. Check the label before buying, especially if you wash your underwear frequently.

Important specifications for comfortable men's underwear

Material: cotton, elastane and stretch jersey

Cotton generally feels soft and is used in many everyday styles. The product information for various sets lists a composition of 95% cotton and 5% elastane. Elastane provides stretch, allowing the fabric to move more easily with your body.

A stretch jersey style may be suitable for work, travel and leisure because the fabric is flexible. If you are primarily looking for a lightweight feel, look for terms such as breathable or moisture-absorbing in the product description. These characteristics should be understood as information provided by the brand, rather than a guarantee of a particular experience.

Fit and length

  • Boxer shorts: offer more coverage around the legs and are suitable for everyday wear.
  • Trunks: have shorter legs and a close-fitting shape, making them useful under slim-fit trousers.
  • Men's briefs: provide less fabric around the legs and may feel comfortable if you want maximum freedom of movement.
  • Men's sports underwear: pay particular attention to a flexible waistband, a smooth finish and a fit that is not likely to shift.

Always check the specific size chart. The same letter size may fit differently from one brand to another. Some charts use EU, FR, IT or UK sizes alongside international sizing.

Waistband, seams and care

An elasticated waistband should feel secure without rolling or pressing into your skin. A smooth finish may help reduce visible lines and friction under clothing, but actual comfort varies from one wearer to another.

Also check the care instructions. Some LEE styles specify washing at 30 °C, with no bleaching, ironing, dry cleaning or tumble-drying. For its 95/5 cotton blend, Urban Classics recommends washing with similar colours and drying at a low temperature or on the washing line, among other instructions. Always follow the label on the product you receive.

How to choose the right size

Ideally, measure your waist where the waistband normally sits. Compare the measurement with the brand's size chart and do not rely solely on your usual letter size. Underwear should not slide down, but it should not dig deeply into your skin either.

When ordering online, pay attention to the following:

  1. Check whether the stated size uses EU, international or another sizing system.
  2. See whether the style has a close, regular or loose fit.
  3. Take into account the difference between trunks, boxer shorts and men's briefs.
  4. Check the underwear returns policy before completing your purchase.

If you also shop for women, you can use the same approach when choosing women's underwear: compare the material, size, leg openings, waistband and care instructions. Products made with modal, cotton or elastane may feel and fit differently from men's styles.

Frequently asked questions about men's underwear

How often should you replace men's underwear?

This depends on how often it is worn, how often it is washed and the condition of the fabric. Replacing it makes sense when the waistband no longer fits properly, the seams start to come undone, the fabric becomes thin or the fit changes permanently. A multipack allows you to rotate several pairs, so you do not have to wash the same pair every day.

What is suitable under smart trousers?

Trunks or close-fitting boxer shorts usually have shorter legs and a more compact shape. This can make them practical under slim-fit trousers. Choose a size that does not feel tight, and check that the seams and waistband do not show through.

Are cotton boxer shorts suitable for sport?

Cotton boxer shorts can feel comfortable during light activity. For more intense movement, you may also want to look for a stretch style, a flexible waistband and a smooth finish. Suitability depends on your preference, the fit and the specific product features.
