Breathability helps disperse your perspiration as vapour.

What is perspiration and where does it come from?

Perspiration is secreted by the sudoriparous glands located just below the skin’s surface. There are two kinds of sudoriparous glands.


Eccrine glands

They play a key role in regulating body temperature (heat, physical effort). The perspiration they secrete has no odour and is essentially made up of water, mineral salts and lactic acid.


Apocrine glands

These are located under the armpits. Their activity is not triggered by heat but instead responds to psychological stimulus (emotions, stress). This perspiration is rich in lipidic, uric and ammoniac components. Though different from the previous type of perspiration, this type of sweat is also odourless.


How do my clothes help to aggravate this phenomenon?

Cotton is hydrophilic. In fact, cotton clothing actually absorbs perspiration. The problem is that once it is absorbed, perspiration is stored inside a fabric’s fibres, which is an ideal setting for bacteria to cause unpleasant odours to proliferate. And the more you perspire, the more this problem spreads. This is how sweat rings OR rings are formed.

So where do unpleasant odours come from?

Odours aren’t caused by perspiration but by bacteria that are naturally present on the skin’s surface. These bacteria are nourished by absorbing perspiration secretions, transforming and then expelling them as odorous molecules. Other secondary factors also influence body odours like hairiness or diet.

What difference does the INDUO® fabric bring?

It avoids sweat rings

Unlike traditional cottons that become saturated with water, INDUO® fabric repels liquids and thus perspiration. This limits the spreading of rings.


It evacuates perspiration

we have made INDUO® fabrics breathable, so that perspiration do not remain in the garment. Perspiration is naturally dispersed since it evaporates into the air as gas. But INDUO® fabrics repel liquid, not gas. So their breathability helps gas pass quickly through the fabric. For this reason, your perspiration is dispersed rapidly.


Ultimately you avoid the formation of rings and the development of the bacteria that will cause unpleasant odours.
