T-Shirt Against Sweat Marks – How Bamboo Works

Short answer: A t-shirt in bamboo viscose is one of the most effective remedies against visible sweat marks. The fabric absorbs and spreads the sweat, so it evaporates instead of gathering as dark patches under the arms, and at the same time it inhibits the bacteria that create odour.

Why do sweat marks appear?

Sweat marks become visible when the fabric cannot move the moisture on fast enough. Cotton soaks up the sweat and holds on to it, so the patch grows and turns dark, while polyester does not take up moisture at all and instead leaves the sweat on your skin. Neither of them solves the problem.

How bamboo viscose works

Bamboo viscose can take up large amounts of moisture and spread it over a larger area, so it evaporates faster. The result is that the patch rarely has time to become visible, and that the t-shirt dries quickly again. Read the full explanation in bamboo and temperature regulation, and see the selection of bamboo T-shirts for men and bamboo T-shirts for women.

Extra help on sweaty days

Choose dark or marled colours, where any marks show the least, and avoid light blue and grey in plain cotton, which show everything. If you have to wear a shirt, a bamboo undershirt can catch the sweat before it reaches the outer layer. If you sweat a lot during sport, read bamboo for training as well.

Frequently asked questions

Does a bamboo t-shirt help against sweat marks?

Yes. Bamboo viscose spreads the moisture over a larger area, so it evaporates, instead of gathering as visible dark patches under the arms.

Which t-shirt colour hides sweat best?

Black, navy and marled dark colours hide sweat marks best. Light grey and light blue in plain fabric show them most clearly.

Does a bamboo t-shirt smell less of sweat?
