The Chi`ll-Its 6668 Hi-Vis Safety Cooling Vest is made with advanced polymer-embedded technology that quickly activates with water to provide hours of core cooling relief. This cooling vest consists of three layers: 1) an ANSI/ISEA 107 Type R, Class 2 high visibility shell, 2) polymer-embedded mid-layer and 3) a water-repellent liner to help keep wearers dry. This comfortable cooling vest is designed to be lighter and less bulky than most cooling vests on the market. Breathable mesh along the bottom of the vest reduces weight, enhances airflow and prevents excess water from dripping onto clothing. Loops along the interior of the neckline allow wearers to insert cooling towels for additional cooling relief along the neck. Also features 2 lower interior pockets for storage, 1 chest exterior pocket and a zippered closure for easy on/off. For best results, wear this body cooling vest over a t-shirt. The water-repellent liner keeps the interior as dry as possible when activated, though wearers should expect to feel some dampness/wetness. Heat-related illness continuously ranks among the top causes of worksite accidents and fatalities. Evaporative cooling technologies such as embedded polymers are a simple, effective and comfortable solution for heat stress prevention. Similar to how sweat cools the body, evaporative technologies use an external water source to draw heat awayhelping to regulate body temperature while providing cool relief. When activated, this cooling safety vest is comfortable and refreshing for even the hottest days of the year. HOW TO ACTIVATE Soak in water for 2-5 minutes to activate. The embedded polymers will retain water for up to four hours of cooling relief. Once dry, simply resoak to reactivate cooling. Hand wash, hang dry. This high visibility cooling vest is ideal for those working on hot job sitesparticularly those requiring ANSI 107 compliance such as road construction, municipalities and baggage handling.
