Understanding the concept of breathable fabric
A fabric is considered breathable when it allows good air circulation inside the garment and on its surface.
Breathable fabrics effectively wick away sweat and moisture, while providing a feeling of freshness. They are therefore particularly suitable for hot weather and sports activities.
The criteria and advantages of a breathable fabric
The breathability of a fabric depends on various criteria. Here are the advantages of types of breathable fabrics:
- Its ability to absorb moisture
- Its anti-odor benefits
- Its quick-drying properties
- Its high lightness and porosity
- The spacing of its fibers
- Its thermal conductivity
The more a fabric meets these criteria, the better it will regulate body temperature and moisture.

Sweating and the choice of clothing material
The role of sweating
Sweating is a natural mechanism for thermoregulation in the body. When it is hot, the body secretes sweat to cool down through evaporation.
The importance of choosing the right material
The choice of clothing material is therefore a key factor in promoting this evaporation, avoiding the unpleasant feeling of wearing damp clothing that sticks to the skin, and maintaining a feeling of freshness.
The consequences of choosing the wrong material
Wearing a non-breathable material that traps perspiration can lead to:
- A feeling of heaviness, discomfort, and heat
- Itching and skin irritation
- The development of unpleasant odors
- The proliferation of bacteria that cause infections
Polyester and perspiration: a combination to avoid?
Polyester, a synthetic material often used in textile manufacturing, has a poor reputation for breathability. However, certain textile innovations now make it possible to design polyester clothing that is more breathable.
