Cooling vests have been around for a while and have proven themselves during the hot summer days! They not only provide extra comfort, but also reduce the risk of heat stress, fatigue and loss of concentration. The Cooling Vest Dry Evo from Macna is no exception! How does it work? The vest is activated by filling it with 600ml (tap) water. Then you put on the vest (preferably in combination with a blow-through jacket, this provides a maximum cooling effect) and then enjoy the much-needed cooling during hot summer days! The technology makes it possible! Due to the application of a patented technology, the available water evaporates in a controlled manner. Unlike conventional vests that use similar cooling techniques, this vest stays dry both inside and out. And the useful life is many times longer thanks to the efficient regulation of the evaporation process! Fully filled, it has the capacity to cool for one to three days, depending on the ambient temperature in which you drive. In addition to the long service life, it also has a long service life. The vest is washable and even after many washes, the vest provides cooling without getting wet! Maintenance: The vest should be hung up after use so that the moisture can be drained. After the vest is completely dry, the vest can only be stored. Features: Materials: Polyamide, Polyester, Core Rayon. Ventilation holes. Macna Ziplock closure.
