You wear underwear for hours at a time, often without giving it much thought. Yet the wrong choice can quickly lead to a tight waistband, visible seams or fabric that loses its shape after just a few washes. Anyone searching online for underwear will also encounter plenty of claims about softness, moisture management and antibacterial properties. Not every claim tells the full story.
As a Joybuy Product Recommendation Officer, I focus primarily on verifiable information: material, sizing, cut, care and intended use. This helps you avoid paying solely for a brand name or eye-catching marketing claim.
Sizing varies by brand and style. A women’s brief in size M may fit differently from a men’s boxer in size M. Some Utree models, for example, list body measurements such as 160/90, 165/95 and 170/100. Urban Classics, on the other hand, uses waist and hip measurements in centimetres.
Always check:
A model that is too tight can dig into the skin. One that is too loose may ride up or create visible folds beneath clothing.
Terms such as antibacterial underwear generally describe a treatment or material used in a specific part of the garment. According to the product description, Utree briefs feature a cotton gusset with a manufacturer-stated 10A antibacterial property. This is a manufacturer’s product claim, not an independent guarantee or medical claim.
Also check where the property applies. An antibacterial gusset does not automatically mean that the entire brief has been treated. Care instructions can likewise affect how long a treatment remains effective.
An underwear 3-pack or underwear 5-pack may appear cost-effective, but the number of pieces says nothing about fit or care requirements. A multipack is only genuinely practical if the style feels comfortable and can be washed according to the care label.
Consider:
Cotton underwear is a sensible choice for everyday wear if you value a natural fibre and a familiar feel against the skin. An elastane blend provides additional stretch. According to the product information, Reebok Carina is made from 95% cotton and 5% elastane.
Modal underwear generally feels smooth and supple. According to the description, the Utree modal styles are made from beechwood modal, combined with other materials in the gusset. With products like these, always check the full composition, as “modal” does not mean every part of the garment is made from modal.
Synthetic fabrics such as polyamide and elastane can be useful for a smooth, close-fitting silhouette. The LEE Seamless Brief is listed as 90% polyamide and 10% elastane. This makes it an interesting option beneath close-fitting clothing, although its feel differs from cotton.
The following styles are practical for everyday wear:
A smooth waistband is not automatically more comfortable. Consider the combination of width, stretch and placement. Calvin Klein’s Icon Cotton Stretch styles are described as featuring a seamless Infinity Bond waistband. This is a verifiable construction detail; how it feels in practice remains a personal matter.
Wash underwear according to the care label. Many of the products in this selection specify washing at 30°C, no bleaching and no tumble drying. Heat can cause elastane and elastic bands to lose their resilience more quickly.

This is clearly a single-use product, not a replacement for washable everyday underwear. The packaging states that the pieces are individually wrapped.
100% cotton according to the product information, classic brief cut, size L for hips measuring approximately 99–109 cm and three individually wrapped pieces.
For close-fitting clothing, LEE seamless briefs may be a practical choice. The Seamless Brief described here has a stretchy construction and a polyamide-and-elastane composition. If you prefer a higher proportion of natural fibres, consider cotton women’s briefs such as the Utree Pure Cotton Antibacterial Briefs. According to the manufacturer, these feature an extra-long gusset, a 3D cut and a 3-pack. The antibacterial property applies to the gusset, according to the product description.
For men who prefer a low-rise, close-fitting style, the Calvin Klein Icon Cotton Stretch Low Rise Trunks are available in a 3-pack. The product information lists cotton with elastane, a contoured pouch and a seamless Infinity Bond waistband. Check the available sizing carefully; the displayed variants include 3XL, among others.

That depends on the fabric, washing frequency and overall condition. Replace briefs or boxers when the fabric becomes thin, the elastic no longer recovers its shape, seams start to come undone or the garment no longer stays securely in place. There is no fixed replacement period that applies to every style.
Cotton can be suitable for everyday wear if you are looking for a breathable, familiar material. A little elastane can improve freedom of movement. Always check the full composition, as the gusset, waistband and main fabric may be made from different materials.
Disposable underwear can be practical when access to a washing machine is limited, for example during travel or a temporary recovery period. However, calculate the cost per wear and consider the waste involved. For extended everyday use, washable underwear is generally the more reusable choice.
