Undershirt for men who sweat under the arms

Short answer: If you sweat a lot under the arms, a soft, breathable undershirt in a calm fit helps keep moisture away from your shirt or sweater. Change daily, wash following the care label, and talk to your doctor if the sweating is very heavy.

Why the armpits sweat the most

The armpits have many sweat glands and sit closed, so the moisture stays there. You sweat from warmth, effort and nerves, and that is normal. What you can do with clothing is choose a layer that takes up moisture and lets air reach the skin, so you feel less clammy.

What an undershirt does

An undershirt sits between the skin and your outer clothes and takes up part of the sweat. That means the shirt or sweater gets less moisture, and you can change the innermost layer instead of everything. It makes the biggest difference when the outer clothing is hard to wash or dry.

Fit at the armhole and shoulders

An undershirt should fit snugly enough to stay put, but not so tight that it rubs at the armhole. Check that the edges do not cut in when you lift your arms. Reach up and twist your upper body so you know whether the fabric moves with you without pulling.

The fabric next to the skin

Soft, breathable fabrics often feel more pleasant when you sweat than dense, smooth ones. Feel the fabric and choose the one that feels light between your fingers. You can see the options as bamboo tank top for men, which have no sleeves and therefore sit less around the arms.

What the outer clothing requires

Dark, thin clothing shows sweat clearly, and light colours can show marks over time. Think about what you wear over the undershirt and choose to suit the day. Under a shirt a thin, skin coloured undershirt can be discreet, while a wider tank top fits under a T-shirt.

Changing and an extra undershirt

On warm days or after demanding meetings, an extra undershirt in your bag is a small, calm safeguard. You can change in the toilet and put the used one in a bag. Then the afternoon starts on a dry, clean base without you having to take off the whole outfit.

Washing so the smell does not settle

Hang the undershirt to dry when you get home, and wash it promptly following the care label, usually at a low temperature and without too much fabric softener. It can leave a film on the fabric and hold on to smells. Let it dry fully, and change the wash if the smell does not go away.

The rest of the innermost layer

The innermost layer consists of more than the undershirt. Underwear and T-shirts against the skin should likewise be soft and breathable. See bamboo boxer briefs and bamboo T-shirts for men, so you can put together the whole layer without any piece rubbing or feeling clammy.
