Buying underwear online may seem straightforward, but a good-looking photo and a familiar brand name do not tell you everything about comfort. The wrong size, a waistband that is too tight or a material that does not wick away enough moisture can leave your purchase unused in the drawer.
Pay particular attention to these common pitfalls:
For comfortable everyday underwear, the fabric is an important starting point. Cotton feels soft and can absorb moisture. Many styles combine cotton with elastane, allowing the underwear to stretch and retain its shape more effectively. One example is the LEE BRIEFS LILIOP, which, according to the product information, contains 95% cotton and 5% elastane.
For sports underwear, you will often see a combination of cotton and synthetic fibres. According to the product specifications, the Reebok Sports Trunks JAY are made from 57% cotton, 38% polyester and 5% elastane. Polyester can help provide a lightweight, flexible feel during movement. Always check, however, whether “moisture-wicking” or “moisture-managing” is a specific product feature rather than just a general advertising claim.
If you are specifically looking for cotton underwear, breathable underwear or stretchy underwear, it is worth reading the full composition. A natural fibre does not automatically mean that every style is suitable for intense exercise, while synthetic fibres are not necessarily less comfortable.
A good fit prevents underwear from slipping down, rolling up or riding up as you walk. So look at:
For women’s underwear, the cut and coverage are just as important. Women’s briefs generally offer more coverage than a women’s thong. A thong can be practical under close-fitting clothing, while briefs may be more suitable for many people as comfortable everyday underwear.
When ordering online, pay attention to your body measurements in centimetres, not just XS, S, M, L or XL. For example, the Utree styles use size indications such as M (160/90), L (165/95) and XL (170/100). These measurements should always be compared with the size guide on the product page.
Some women’s styles are marketed as antibacterial women’s underwear. Assess such descriptions carefully. According to Utree’s own product description, the relevant styles feature a gusset marked “10A antibacterial”. This is a brand or product claim; it is not a reason to regard any medical or hygienic effects as guaranteed.
Also look at practical details, such as:
A longer gusset construction can provide additional coverage, but actual comfort still depends on size, body shape and personal preference.

We have put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
Even well-fitting underwear can quickly lose its shape if washed incorrectly. Check the care label before every purchase. Many styles in this selection are machine washable, but advise against bleaching and tumble drying, and recommend ironing at a low temperature. The LEE styles state that they should be washed at 30 °C; some Reebok styles specify 40 °C.
Where possible, wash underwear at the lowest temperature stated on the label. Use a laundry bag for delicate styles and avoid using too much detergent. Replace an item when the elastic remains loose, the seams cause irritation or the fabric has become thin and misshapen. Its practical lifespan depends on how often it is worn, your washing routine, the material and the fit.
Measure your waist or hips with a flexible tape measure and compare the result with the size guide for the specific product. Do not rely solely on your usual size, as brands and styles can fit differently.
A multipack can reduce the price per item and makes it easier to build up a supply for everyday wear. However, compare the total price, number of items, fabric composition and care instructions. A cheap pack is not a good deal if you do not like the fit.
Choose sports underwear with a secure waistband, plenty of stretch and a cut that does not ride up. Product descriptions for sports styles sometimes mention breathable fabric or moisture management. Treat this as information provided by the brand, and also check that the composition and size suit your activity.
