What should you look for in good underwear?
A useful underwear comparison looks beyond appearance. The most important factors are fabric quality, construction and function. Breathability is key to keeping you comfortable and dry. Flat or seamless construction helps prevent chafing.
The waistband should stay in place without digging in or rolling. Check that the fabric has enough stretch to let you move freely and still hold its shape. Leg length also affects how comfortable underwear feels under different pants.
Tip: Try on new underwear at home first. You can check whether the fabric feels scratchy or the seams rub before wearing it all day.
Why fit matters
The right fit is personal and depends on your body shape and preferences. A snug fit provides more support, but the wrong size can dig in. A looser cut gives you more room to move but may ride up or bunch.
Compare the cuts available from different brands. Some are designed for athletic builds, while others may suit slimmer or fuller figures. Sizing can vary between manufacturers, so take your measurements again from time to time.
How do the materials compare?
Fabric is the main factor affecting comfort, temperature control and durability. There are plenty of options, each with its own pros and cons.
Cotton is a classic choice. It's soft, breathable and gentle on the skin. Pure cotton absorbs moisture well, but takes longer to dry. It's a great option for everyday wear. Explore our underwear category to find a range of cotton styles.
Merino wool is a natural performance fabric. It regulates temperature well, wicks moisture away from your skin and naturally resists odors. It's a good choice for activities and travel.
Synthetic blends made from polyester, polyamide and elastane are lightweight, quick-drying and hold their shape. They often provide excellent support during workouts, though the quality of synthetic fabrics can vary widely.
Warning: Low-quality synthetic fabrics may develop an unpleasant odor in hot weather or when you sweat because they don't absorb moisture well. Look for odor-control technology.
Sustainable fabrics are becoming more popular
More manufacturers are using sustainable fabrics, including organic cotton, Tencel (Lyocell) made from wood and recycled polymers. These materials help conserve resources and can perform just as well as conventional alternatives.
Choosing these fabrics can help reduce the environmental impact of your clothing. Explore our clothing category to find sustainable options.
How can you find the right fit?
Finding the right size is essential. Underwear that's too tight can dig in and restrict movement. Styles that are too loose may slip, chafe or bunch up.
Use a tape measure to check your waist at the height where the waistband sits. Then measure your hips at the widest point. Compare both measurements with the manufacturer's size chart instead of relying on your usual clothing size.
Keep shrinkage in mind. Natural fabrics such as cotton may shrink slightly in the first wash, so sizing up can make sense. Synthetic blends usually hold their shape.
Different cuts for every body type
Boxer shorts come in a range of cuts. Classic boxers have a loose fit and give your legs plenty of room. Closer-fitting boxer briefs are shorter and offer more support. The best choice depends on your preference and what you plan to wear over them.
With slim-fit pants, seamless or flat-seam boxer briefs are a good choice because they help prevent visible lines. For loose-fitting pants or relaxing at home, classic boxer shorts may feel more comfortable.

Striped styles as a fashionable alternative

How to care for your underwear so it lasts
Proper care can significantly extend the life of your underwear. Wash new items before wearing them for the first time to remove any manufacturing residue and soften the fabric.
Wash underwear at 30°C or 40°C with a mild detergent. Avoid fabric softener, which can reduce the absorbency of natural fibers and damage the elasticity of waistbands.
Fasten all closures, such as buttons or hook-and-loop fasteners, before putting laundry in the washer. This helps protect fabrics from damage. Turn garments inside out to help preserve their color.
Drying and storage
The tumble dryer is the biggest enemy of elastic. Air-drying your underwear is a better choice. Keep dark colors out of direct sunlight to prevent fading.
Store your underwear in a dry, well-ventilated place. Overstuffed drawers can affect the shape of waistbands. Fold or roll your boxer shorts to save space.
What to expect from 2026 trends
The underwear industry is constantly evolving, and clear trends are emerging for 2026. Sustainability remains a key focus, with even more products made from recycled materials and produced under fair working conditions expected.
