Underwear may seem like a simple purchase, but small differences determine whether briefs, thongs or boxer shorts remain comfortable. A waistband that is too tight can dig in, seams may show beneath clothing and fabric that does not breathe sufficiently can quickly feel too warm. If you only look at colour, brand or discount, you will often discover these drawbacks after just a few wears.
This buying guide helps you compare women’s and men’s underwear based on verifiable product information. That way, you can choose comfortable underwear for everyday wear, sport, travel or during your period.
Sizes vary by brand and model. An M in men’s boxer shorts does not necessarily have the same waist measurement as an M in women’s briefs. Always check the size chart and, if necessary, measure your waist or hips. Pay attention to the cut too: a low-rise style sits lower on the hips, while briefs or high-coverage briefs offer more coverage.
Words such as “breathable”, “soft” or “antibacterial” only tell you something when the product description specifies the material and construction. For products with an antibacterial gusset finish, according to the brand’s product information, this may be linked to a specific treatment or material. This is not a medical claim and does not replace personal advice or good hygiene practices.
A 3-pack or 5-pack of underwear can be practical, but first check whether the colours, size and styles suit your wardrobe. A set in the same colour is useful for everyday wear; different colours may work better with light and dark clothing. Packs containing several items are often practical for travel, while buying a single style is useful when you want to try the fit first.
Cotton underwear generally feels familiar and is often chosen for everyday wear. Always check the exact composition: “cotton” may be combined with elastane for stretch and shape retention.
Modal underwear is often described in product listings as having a smooth, supple feel. The Utree modal styles specify beechwood-based modal fabric combined with stretch properties. The feel can vary from person to person, especially if you are sensitive to warmth or tight edges.
Polyamide and elastane are often used in seamless underwear. These fabrics make a smooth, stretchy construction possible. This can feel comfortable beneath close-fitting clothing, but also check the care instructions and the proportion of synthetic fibres.
For everyday wear, a soft waistband and a gusset that stays securely in place are important considerations. With thongs, the main priorities are minimal coverage and fewer visible lines beneath clothing. Briefs with fuller coverage provide more fabric around the hips.
For men’s underwear, boxer shorts and trunks offer a different balance between support and freedom of movement. Pay attention to the leg length, rise and whether there is a contoured pouch or fly. For sports underwear, it is important to have an elasticated waistband that does not roll over or shift during movement.
Wash underwear according to the product label. Several selected styles specify washing at 30 °C and recommend not tumble-drying. Heat can put additional strain on elastane and elasticated waistbands. Use a mild detergent, avoid bleach when it is not permitted and check the seams after several washes.
A style needs replacing when the waistband no longer sits securely, the fabric becomes thin or the shape visibly changes. Its lifespan depends on how often it is worn, washed and dried, as well as on the material.

Measure your waist and hips according to the method specified in the brand’s size chart. Compare the measurements in centimetres with the product page and consider the fit too. If you are between two sizes, a roomier style may feel more comfortable for everyday wear, while sports underwear usually needs to fit snugly without digging in.
This depends on the material, how often it is worn and how it is cared for. Check the stretch in the waistband, thin areas and any lasting distortion. Washing according to the label, avoiding excessively hot drying and rotating between enough different items can help the underwear retain its shape for longer.
It depends on how you intend to use it. Cotton is often chosen for a familiar, soft feel in everyday wear. Seamless underwear can be more practical beneath tight-fitting clothing thanks to its smooth construction. Rather than looking only at the material name, compare the fibre composition, fit, seams and care instructions.
