Our advanced cooling technology is designed to reduce the temperature of your clothes and skin, providing relief from the heat and helping you stay comfortable all day long.

Why should you add our treatment to your fabrics ? For starters, it can help you avoid the discomfort and health risks associated with overheating, such as dehydration, heat exhaustion, and heat stroke. Our cooling technology works by absorbing and dissipating heat from your body, reducing the temperature of both your clothes and skin. But that’s not all – our treatment also helps to reduce sweating and odor, keeping you feeling fresh and confident even in the most challenging conditions. This can be particularly beneficial for athletes, outdoor workers, and anyone else who spends time in hot and humid environments.

Effectiveness or expected / benefit

Through an endothermic phenomenon, COOL’IN® crystals locally lower the temperature in contact with humidity to -2.5°C. The fabric is immediately dried thanks to its hyper-hygrophy.

Efficient ecotechnology

Features high-performance microencapsulated technology that ensures long-lasting effectiveness for up to 10 washes.

Absence of harmful substances

Thanks to the mineral crystals, COOL’IN® offers textiles excellent temperature and humidity management. It’s naturalness index is 89%.

Compliant and responsible

Responsible and sustainable, the COOL’IN® solution is safe for people and the environment.


The COOL IN® solution reduces the temperature of textiles by 2.5°C. In the presence of moisture, the crystals react instantly. Moisture is instantly absorbed and diffused through the fabric.

Observed results : overall decrease of 2 to 3°C.

Action mechanism

Through an endothermic phenomenon, COOL’IN® is designed to manage the absorption of moisture and refresh textiles in the presence of a source of humid heat (sweating, humidity…).

Supports and treatments

COOL’IN® technology makes textiles functional by giving them a cooling power.
