Good men’s underwear needs to be comfortable, stay in place and withstand regular washing. Yet it’s tricky to tell from a product photo alone whether a style will suit you. Marketing terms like “sporty”, “breathable” or “stretch” only really mean something when you also look at the fabric composition, fit and care instructions.
In this buying guide, you’ll discover what to look for when choosing men’s underwear, from men’s boxer shorts to trunks and hip briefs for men. We’ll also compare a few practical options for everyday wear, sport and larger sizes.
A size M isn’t the same across every brand. The waist width, rise height and leg length can all vary. An elastic waistband that’s too tight can dig in uncomfortably, while a boxer that’s too loose may shift around when you move.
Always check the following:
With men’s underwear in larger sizes, the waist measurement is more important than just the size label. A product page with a concrete size guide helps you avoid ordering the wrong thing.
Many cotton men’s underwear items are actually a cotton blend with elastane. That’s not automatically a bad thing: elastane can provide more stretch and a closer fit. The difference lies in the composition.
Pay attention to the percentage:
Don’t take a brand’s claim about moisture management as a guaranteed benefit. According to Calvin Klein’s own research, a plant-based water-repellent finish can support wearing comfort; the experience may vary from person to person.
A men’s underwear multipack is practical, but a larger number of pieces isn’t automatically better value. Compare the price per pair and check that all the pieces are the same colour, size and style.
A 3-pack of boxer shorts is handy if you want to try a fit first. A 5-pack of boxer shorts is better when you’re looking to stock up for everyday use. Also check the care instructions: some styles can’t go in the tumble dryer or need ironing on a low temperature.
Men’s boxer shorts usually have longer legs and offer more coverage. They work well under jeans, chinos or sportswear, as long as the leg doesn’t ride up.
Men’s trunks are shorter than classic boxer shorts. They combine a close-fitting look with relatively little extra fabric, making them suitable for daily wear and movement.
Men’s hip briefs have short sides and cover less of the upper thigh. They’re a practical choice when you want a compact style with freedom of movement.
For everyday use, cotton blends with around 5% elastane are a common choice. The fabric can then fit more closely and move with you. For sport, it’s not just the material that matters, but also the waistband, seams and leg length.
Look for concrete details rather than general wording:
How long your underwear lasts depends on how often you wear it, how you wash it, the temperature and drying method. Wash your underwear according to the label and avoid the tumble dryer if it’s not recommended. Calvin Klein advises machine washing some styles at 30 °C and not tumble drying. Reebok styles mention, among other things, not bleaching and ironing on a low temperature.
A sturdy waistband and reinforced seams are useful product specifications, but they don’t guarantee that an item will last the same length of time in all conditions.

That depends on how often you wear it, how many pairs you have and how you care for it. Replace a pair when the elastic waistband is permanently loose, the fabric becomes thin or the seams start to come apart. A multipack can help spread the wear across each pair.
For everyday wear, many men choose a cotton blend with elastane, because that combination offers softness and stretch. Stretch men’s underwear can be comfortable for movement, but always check the percentage of elastane and the stated fit. If you prefer a less close-fitting feel, it’s better to look for a relaxed fit.
Black men’s underwear is easy to match and less prone to visible discolouration from daily wear. White can be handy under light-coloured clothing, while multipacks with several colours offer more variety. Focus mainly on the fabric, fit and size; colour doesn’t affect wearing comfort.
