The Coolvest is a dry cooling jacket whose cooling process takes place thanks to the evaporation of water.

It is comfortable, light, easy to fill and only activates the cooling process when necessary. No source of energy, refrigeration, gel or any other additional chemical product required.

Thanks to its patented system, the jacket is neither humid nor wet. It can therefore be worn under other clothes. It is intended for professional use.

When the Coolvest jacket is filled with drinking water (max. 600 ml), the cooling process takes place immediately. Cooling takes place thanks to the evaporation of water present in the jacket.

Technical fibres make it easy to wear the jacket in all circumstances because it is totally dry on the outside. The Coolvest jacket cools the area of the cardio-vascular system on the upper part of the body where heat stress is greatest.

 This dry cooling technology enables the cooling process to take place automatically and functions constantly and efficiently. The Coolvest jacket can reduce temperatures by as much as 20 °C below room temperature, depending on the rate of humidity.
