Underwear for men who sweat a lot in the groin
Oct 06, 2026
Short answer: If you sweat a lot in the groin, it helps to choose a soft, breathable fabric, a fit that does not press, and to change into dry clothes when you can. Clothing does not remove the cause, but it can make the day more comfortable.
Sweating is perfectly normal
The body sweats to cool down, and the groin is a place where heat is easily trapped, because the skin lies close together. How much someone sweats varies a great deal from person to person. It is nothing to be ashamed of, but something you can make everyday life easier around.
The fabric next to the skin
A soft, breathable fabric lets moisture go instead of holding it against the skin. Fabric that feels clammy when wet quickly becomes a nuisance. Feel the fabric when you choose, and take two or three sets, so you can change when a pair has had a long day.
Fit and leg length
If the underwear is too tight, it presses, and the skin gets warm and chafes. If it is too loose, it shifts and creates friction. Find a fit that lies calmly, and consider a longer leg if your thighs rub against each other when you walk.
Layers that help
It also helps to think about what you wear on top. A light, soft layer on the torso keeps the body in better balance, so you do not sweat more than necessary. Look at the bamboo undershirts for men, which are easy to wear under a shirt or a jumper.
Start with what others choose
If you are unsure where to begin, see what others choose again and again. Look at the bestsellers from Copenhagen Bamboo and use them as a starting point to find your own fit. It is not a guarantee, but it makes the first choice easier and less overwhelming.
The clothes on top
Thick, dense trousers hold in heat, and you feel it in the groin. Choose trousers with some air when you can, and think about sweatshirts and sweatpants too, which should give freedom of movement. Look at the bamboo sweatwear when you want something soft that sits comfortably on the body.
Change and wash
Change your underwear as soon as you notice it has become damp, if you have the chance, and bring a spare pair if needed. Wash according to the care label, use mild soap without fabric softener, and let it dry completely. That way odour and moisture settle less in the fabric.
When to talk to your doctor
If you suddenly sweat far more than before, or you are often red, sore or itchy, whatever clothes you wear, talk to your doctor. There may be explanations other than the clothing, and it is better to have it checked than to guess. Good underwear can ease everyday life, but it does not replace a doctor's assessment.
Frequently asked questions
Which fabric is best if you sweat a lot?
A soft, breathable fabric that does not feel clammy when wet is usually the most comfortable. Feel the fabric, and keep several sets so you can change.
Should the underwear fit snugly or loosely?
Snug enough to stay in place, but without pressing. Underwear that is too loose can shift and cause friction, so find a fit that lies calmly.
When should I see a doctor about sweating?
If you suddenly sweat much more than before, or the skin is often red and sore, talk to your doctor. Clothing can help with comfort, but it cannot clarify the cause.
