Underwear for Sweating: Practical Tips for Men
Quick answer: If you sweat easily around the groin, look for breathable materials, a comfortable fit and plenty of freedom of movement. Loose cotton boxer shorts can be particularly comfortable for everyday wear because they absorb moisture and fit less tightly. For sports or heavy sweating, quick-drying performance fabrics are often more practical. The key is to minimize the build-up of heat and moisture.
Why do men sweat around the groin?
Sweating around the groin is completely normal. The body produces sweat to regulate its temperature. In the intimate area, skin, underwear and outer clothing often sit close together, allowing heat and moisture to accumulate more easily.
Common triggers include:
- High temperatures: the body sweats more in summer or warm indoor spaces.
- Tight clothing: limited space between the skin and fabric can restrict airflow.
- Movement and exercise: physical activity increases sweat production.
- Prolonged sitting: heat can build up, especially under tight trousers.
Which underwear makes you sweat the least?
No underwear can completely stop natural sweating. However, the material and fit affect how warm or damp your underwear feels when worn.
| Underwear | Benefits when sweating | Best suited for |
|---|---|---|
| Loose boxer shorts made from 100% cotton | Plenty of freedom of movement and good moisture absorption | Everyday wear, leisure, warm days |
| Fitted boxer briefs made from cotton and elastane | Flexible fit, good support and less fabric movement | Everyday wear, tighter trousers |
| Cotton briefs | Less fabric around the thighs, compact fit | Everyday wear, slim-fitting clothing |
| Performance underwear made from polyester or polyamide | Can wick sweat away from the skin and often dries faster | Sports, intense activity |
If you prefer an especially loose fit, Cotton Majesty men’s boxer shorts include styles made from 100% cotton with a generous comfort cut. They offer plenty of room around the groin and thighs. If you prefer more support under your clothes, take a look at our fitted boxer briefs.
Cotton or performance fabrics: Which is better for sweating?
Cotton feels soft against the skin, allows air to pass through and absorbs sweat well. However, it takes longer to dry when it becomes very damp.
Performance fabrics such as polyester and polyamide can move moisture away from the skin and dry more quickly. However, they are usually made from petroleum-based synthetic fibres, can release microplastics during washing and may sometimes contribute to sweat odours. They are often practical for sports, while many men find cotton comfortable for everyday wear.

How can you reduce sweating between your legs?
Sweating cannot be prevented completely. However, a few simple habits can help reduce heat, moisture and friction:
- Choose looser clothing: comfortable underwear and trousers that are not too tight leave more room for airflow.
- Pay attention to materials: cotton absorbs moisture, while performance fabrics may dry faster during intense activity.
- Change damp underwear: especially after exercise or on hot days, a fresh pair may feel more comfortable.
- Dry the groin area thoroughly: after showering, make sure the skin is as dry as possible before putting on clean underwear.
- Avoid friction: choose the right size and leg openings that neither dig in nor cause uncomfortable rubbing.
Frequently asked questions about groin sweating
How can you reduce sweating in the groin area?
Gentle, regular washing and thorough drying help reduce moisture and skin irritation. Avoid harsh personal-care products and put on fresh, dry underwear after showering.
Why does underwear smell unpleasant after sweating?
Fresh sweat usually has very little odour. Unpleasant smells mainly develop when bacteria on the skin break down components of sweat. Regular washing and clean underwear help limit odour.
How often should you change underwear if you sweat a lot?
Changing underwear daily is generally recommended. If your underwear becomes very damp after exercise, in hot weather or during physical work, an additional change may be helpful.
When should you see a doctor about groin sweating?
If you sweat unusually heavily without heat or physical activity, or if persistent redness, itching or sore patches develop, medical advice is recommended. Moisture and friction can contribute to skin irritation.
