Unlike traditional round-section textile fibres, Becool® has a four-pointed star shape. This unique structure gives Becool® exceptional moisture management and thermoregulation properties.

Increased Contact Surface
The star shape of the four-lobed fibres increases the contact surface with the skin and air, allowing for optimal sweat absorption and evaporation.
Thanks to its 4-channel section, the diffusion surface of BeCool fibre is larger than that of a round-section thread. Acting like a fan blade, it channels the warm, moist air emitted by the skin and helps to evacuate it towards the outer layer of the double-sided fabric.

Moisture Transport Channels
The branches of the four-lobed section create capillary channels that facilitate the rapid transport of moisture to the outside of the fabric, where it evaporates easily.
Renew Air Flow is an air circulation mechanism that circulates fresh, dry air from outside to the skin.

Improved Ventilation
The four-lobed fibre structure promotes better air circulation through the fabric, helping to keep the skin dry and regulate body temperature.
The Self Sweat Extractor is a mechanism that creates a vacuum between the fabric and the skin, thereby drawing heat and moisture outwards.
